尽管更多方面的业务受到人口改变的影响，例如消费的改变或储蓄和投资，还有资金的花费，我们把注意力集中劳动力老龄化促使人事政策的变化上。
涉及广泛的人力资源管理政策，以有关进行创新和技术变化的招募问题为开端。
1 老化的劳动力及人力资源管理由于人口的变化，公司劳动力的平均年龄在未来将会更年长。
因此，劳动力高于50的年龄结构占主导地位的集团不再是一个例外，并将成为一个制度。
在此背景下，年长的工人的实际份额，以及最优份额，部分是由企业特征的差异加上外在因素决定的。
2 一般的挑战尽管增加公众对未来人口转型带来的各种挑战的意识，公司对于由一个老化劳动力引起的问题的意识仍然是相当低的。
事实上，只有25%的公司预计人口统计的变化在长远发展看来将会导致严重的问题。
然而，现在越来越多关于老化劳动力呈现的挑战和潜在的解决方案的文献。
布施提出了一种分析老员工一般能力的研究文集，并给出有关于年长工人的人力资源政策的实例。
目前，华希特和萨里提出一篇关于研究公司对于提前退休的态度和延长工作生涯的态度的论文。
在这些研究中，老员工的能力通常被认为是不同的，并不逊色，同时指出一个最优的劳动力取决于不同的公司的特殊要求。
一般来说，然而由于越来越缺少合格的员工，人口统计的变化将使得在各种人事政策方面上的压力逐渐增加。
特别是，没有内部人力资源部门的中小型企业，因此缺乏足够的特殊的基础设施，则面临着严峻的挑战。
与他们正常的大约两到五年的计划水平相反，他们将越来越多地要处理长期的个人问题和计划。

外文文献原稿和译文原稿1. IntroductionOver the past two decades, organizations of all types have increasingly acknowledged the importance of customer satisfaction and loyalty. The marketing literature suggests that the long term success of a firm is clearly based on its ability to rapidly respond to changing customer needs and preferences (Narver &Slater, 1990; Webster, 1992). A key motivation for the increasing emphasis on customer satisfaction is that higher customer satisfaction can lead to have a stronger competitive position resulting in higher market share and profitability (Fornell, 1992), reduced price elasticity, lower business cost, reduced failure cost, and mitigated cost of attracting new customers (Chien, Chang, & Su, 2003).The principal focus of this study is on evaluating the efficiency of customer satisfaction and loyalty (CS&L) for existing mobile phone brands in Turkish mobile phone sector. Since the early1990s, with the launch of the mobile phones, there has been a remarkable development both in their product sophistication and their rapid and widespread adoption. With more than three billion subscribers around the world, the extent of mobile phone diffusion in emerging markets has been increasingly larger than that in developed countries (Kalba, 2008). Turkey, being one of the fastest emerging market economies in the world, adopted mobile phone technology in 1994. Since then, there has been a considerable increase in the level of mobile phone ownership, where the number of mobile phone users in the country is expected to reach around70 million by the end of 2013, representing a penetration rate of over 90% (RNCOS, 2010). The significant rise in mobile phone usage can partially be attributed to the fact that Turkey has the youngest population in Western Europe. Turkey currently has the 6th largest young mobile phone user base in the world, with more than 11million subscribers underthe age of 25, providing a very lucrative market for mobile phone companies (Euro monitor International,2010). It should however be noted that the penetration in this market at present is still below the EU average, indicating that the mobile phone sector is not saturated yet, and there is still space for new investors. Currently, there exist nearly more than 10 major mobile phone companies operating in the Turkish mobile phone sector, each having a relatively large product line. As of 2010, the top five mobile phone brands were Nokia, Samsung, LG, Motorola and Sony Ericsson and together they account for nearly 75% of overall market sales. As a new comer, phone is rapidly increasing its market share, but as of the start of this study, did not have a significantly large presence. In terms of market share, Nokia has been undisputedly the market leader (36.4% of sales) with Samsung featuring second (19.5%) and LG ranking third (10.1%) (Patron Turk,2010).Commensurate to its widespread diffusion globally, there has been a growing worldwide academic interest in mobile phone usage which focuses mainly on examining its contribution to social life, user preferences and its ergonomic features (Bag chi, Kirs, & Lopez, 2008). A number of empirical studies were also conducted within the context of Turkish mobile phone sector. The topics of these studies ranged from examining motivation of use (Dedeoglu,2004; Oscan & Kodak, 2003) to mobile phone selection (Isiklar &Buyukozkan, 2007), from customer satisfaction (Turkyilmaz &Ozkan, 2007) to brand loyalty (Simsek & Noyan, 2009).The methodology used in study to evaluate the relative CS&Lefficiency of mobile phone brands is based on data envelopment analysis (DEA). The traditional DEA technique has long been utilized as an invaluable tool in the field of operations research and management science to solve problems in wide range of industries(Hu, Lai, & Huang, 2009; Lee, 2009; Lin, Lee, & Chiu, 2009) as well as in not-for-profit organizations (Mahajan, 1991; Wu, Liang, &Chen, 2009; Zhang, Huang, Lin, & Yu, 2009); but its diffusion into the field of marketing and related disciplines has been relatively slow. For instance, in the marketing field, DEA has recently been employed as a powerful tool for data analysis in measuring efficiency in retailing sector (Charnes, Cooper, Learner, & Phillips,1985; Donthu & Yoo, 1998; Keh, 2000; Keh & Chu, 2003; Thomas,Barr, Cron, &Slocum, 1998), evaluating website marketing efficiency(Shuai & Wu, 2011), benchmarking marketing productivity(Donthu, Hershberger, & Osmonbekov, 2005; Kamakura, Ratchford,& Agrawal, 1988), and measuring relative market efficiency(Murthi, Srinivasan, & Kalyanaram, 1996) or service quality(Athanassopoulos, 1997; Soteriou & Staurinides, 1997). The assessment of CS&L has always been a major research item on the agenda of researchers in the marketing and related fields, because the issue of how efficiently a firm manages its marketing processes and their relationship with their customers is central to its ability to gain competitive edge vis-à-vis its rivals. The DEA approach adopted in this study illustrates how differences in CS&L efficiency between various mobile phone brands can be ascertained empirically, and thus helps management determine proper policies and courses of action.The rest of the paper is organized as follows. Section 2 reviews the recent literature on customer satisfaction and customer loyalty studies. Section 3 provides an in-depth description of our research methodology. Section 4 presents the results of our analysis. The last section (Section 5) summarizes our findings, describes managerial implications of the study and provides the concluding remarks.2. Background literatureWhile customer satisfaction has been defined in various ways, the high-level conceptualization that appears to have gained the widest acceptance states that satisfaction is a customer’s post purchase evaluation of a product or service (Cronin & Taylor,1992; Westbrook & Oliver, 1991). Customer satisfaction is also generally assumed to be a significant determinant of repeat sales, positive word-of-mouth, and customer loyalty. It has also long been considered as one of the key antecedents of creating brand loyalty (Cronin, Brady, & Hult, 2000; Dick & Basu, 1994; Fornell,Michael, Eugene, Jaesung, & Barbara, 1996; Syzmanski & Henard,2001). Satisfied customers return and buy more, and they tell other people about their experiences, both positive and negative (Fornellet al., 1996).Building on Hirschman’s (1970) exit-voice theory, weakly dissatisfied consumers would be of primary importance to a firm. While strongly dissatisfied consumers generally choose the exit option (i.e., they leave the firm), the weakly dissatisfied customers tendto stay loyal to the firm and rather employ the voice option, which implies overt complaints as an attempt to change the firm’practices or offerings (Fornell &Wernerfelt, 1988). Thereby, proper handling of customer complaints may ensure that weakly dissatisfied consumers remain loyal, and serve as an exit barrier (Fornell,1992; Halstead & Page, 1992). The impact of loyal customers is considerable; for many industries the profitability of a firm increases proportionally with the number of loyal customers and up to 60% of sales to new customers can be attributed to the word of mouth referrals (Reichheld & Sasser, 1990).Within the existing literature on customer satisfaction research, various customer satisfaction models were developed based on a cumulative view of satisfaction. To this end, a number of customer satisfaction indices (CSIs) were designed with most prominent of those being Swedish Customer Satisfaction Barometer (SCSB), the American Customer Satisfaction Index (ACSI) and European Customer Satisfaction Index (ECSI). Of these CSIs, we employed the ECSI model as the backbone of our CS&L efficiency model in this study due to its recent popularity in the literature and its comprehensiveness in CS&L coverage. The ECSI is a structural model based on the assumptions that customer satisfaction is derived by a number of factors such as perceived quality, perceived value, expectations of customers, and image of a firm. These factors are the antecedents of overall customer satisfaction (Turkyilmaz &Ozkan, 2007). The model also estimates the results when a customer is satisfied or not. The four antecedents of customer satisfaction may also have direct effects on customer loyalty(Johnson, Gustafson, Andreessen, Lervik, & Cha, 2001). Each construct in the ECSI model is a latent construct which is operational zed by multiple indicators (Chien et al., 2003; Fornell,1992). The underlying constructs of the ECSI model are explained as follows:The image construct evaluates the underlying image of the company. Image refers to the brand name and the kind of associations customers obtain from the product/company (Andreassen &Lindestad, 1998). Martensen, Kristiansen, and Rosholt (2000)argue that image is an important dimension of the customer satisfaction model. Image is a consequence of being reliable,professional and innovative, having contributions to society, and adding prestige to its user. It is anticipated that image has a positive effecton customer satisfaction, customer expectations and customer loyalty.Customer expectations are the consequences of prior experience with the company’s products (Rotondaro, 2002). This construct evaluates customer expectations for overall quality, for product and service quality, and for fulfillment of personal needs. The customer expectations construct is expected to have a direct and positive relationship with customer satisfaction (Anderson, Fornell, &Lehmann, 1994).Perceived quality is evaluation of recent consumption experience by the market served. This construct evaluates customization and reliability of a given product or service. Customization is the degree to which a product or service meets a customer’s requirements, and reliability is the degree to which firm’s offering is reliable, standardized, and free from deficiencies. Perceived quality is expected to have a positive effect on customer satisfaction (Fornellet al., 1996).Perceived value is the perceived level of product quality relative to the price paid by customers. Perceived value is the rating of the price paid for the quality perceived and a rating of the quality perceived for the price paid (Fornell et al., 1996). Perceived value structure provides an opportunity for comparison of the firms according their price-value ratio (Anderson et al., 1994). In the model, perceived value is expected to have a positive impact on satisfaction.Customer satisfaction construct indicates how much customers are satisfied, and how well their expectations are fulfilled. This construct evaluates overall satisfaction level of customers, fulfillment of their expectations, and company’s performance versus the ideal provider．Customer loyalty is the ultimate factor in the ECSI model. Loyalty is measured by repurchase intention, price tolerance and intention to recommend products or services to others. It is expected that better image and higher customer satisfaction should increase customer loyalty.3. MethodologyThis section presents the research methodology adopted in this study. The following subsections explain the survey instrument, the data collection procedure, and the DEA model.3.1. Survey instrumentThe DEA model of CS&L, which is shown in Fig. 1, consists of the aforementioned constructs which are based on previous research and prominent theories in the field of consumer behavior. The constructs of the CS&L model are unobservable (latent) variables indirectly described by a set of observable variables which are called manifest variables or indicators. The constructs and their constituent items are shown in Table 1. The use of multiple measures for each construct increases the precision of the estimate as compared to an approach of relying on a single measure. In our CS&L efficiency model, all four antecedents of customer satisfaction and loyalty which include image, customer expectations, perceived quality and perceived value were treated as input variables, while the two constructs, namely customer satisfaction and customer loyalty were considered as output variables.The survey questionnaire was designed using a three-step process. First, the consumer behavior literature was extensively reviewed for the manifest variables. Secondly, the questionnaire items were prepared in Turkish and refined through a series of discussions with two senior marketing managers of a prominent mobile phone company and a number of experienced academics in the field of consumer behavior. Finally, the survey questionnaire was subjected to extensive pre-testing and refinement based on a pilot study of 30 mobile phone users. Feedback from this pilot study indicated that some questions were ambiguous, difficult to understand,or irrelevant for mobile phone sector. This pilot study also served as a practical exercise for interviewers. The final questionnaire contained a total of 23 items pertaining to the CS&L. These23 items appeared to have face validity as to what should be measured. All the items were measured on 10-point scales, with anchors ranging from 1 denoting a very negative view and 10indicating a very positive view. Relying on 10-point scales enables customers to make better discriminations (Andrews, 1984).译文1．介绍在过去的二十年中，所有类型的组织都越来越多地承认了客户满意度和忠诚度的重要性。

By phase-shifting technique, we have obtained information of the object wave spreading to a certain distance from the original object. Therefore, in order to get the information of the object wave at its initial spreading position, what we need to do is a reverse work.Fig.1 Geometric coordinate of digital holographyexact registering distance.The focusing functions normally applied can be divided into four types: gray and gradient function, frequency-domain function, informatics function and statistics function. Gray evaluation function is easy to calculate and also robust. It can satisfy the demand of common focusing precision. We apply the intensity sum of reconstruction image as the evaluation function:min ),(11==∑∑==M k Nl l k SThe calculation is described in Fig.2. The position occurring the turning point correspondes to the best registration distanced, also equals to the reconstructing distance d '.It should be indicated that if we only need to reconstruct the phase map of the object wave, the registration distance substituted into the calculation equation is permitted having a departure from its true value.4 Spatial resolution of digital holography4.1 Affecting factors of the spatial resolution of digital holographyIt should be considered in three respects: (1) sizes of the object and the registering material, and the direction of the reference beam, (2) resolution of the registering material, and (3) diffraction limitation.For pointx2on the object shown in Fig.3, the limits of spatial frequency are λξθλθθ⎥⎦⎤⎢⎣⎡⎪⎪⎭⎫ ⎝⎛-'-=-=-0211maxmax tan sin sin sin sin z x f R R Fig.2 Determining reconstructing distanceλξθλθθ⎥⎦⎤⎢⎣⎡⎪⎪⎭⎫⎝⎛-'-=-=-211minmintansinsinsinsin zxfRRFrequency range isλξξ⎥⎦⎤⎢⎣⎡⎪⎪⎭⎫⎝⎛-'-⎥⎦⎤⎢⎣⎡⎪⎪⎭⎫⎝⎛-=∆--211211tansintansinzxzxfso the range is unrelated to the reference beam.Considering the resolution of registering material in order to satisfy the sampling theory, phase difference between adjacent points on the recording plate should be less than π, namely resolution of the registration material.cfff=∆η21)(minmaxπ4.2 Expanding the spatial resolution of reconstruction imageExpanding the spatial resolution can be realized at least in three ways: (1) Reducing the registration distance z0 can improve the reconstruction resolution, but it goes with reduction of the reconstruction area at the same ratio.Therefore, this method has its limitation. (2) Increasing the resolution and the imaging size of CCD with expensive price. (3) Applying image-synthesizing technique[11]CCD captures a few of images between which there is small displacement (usually a fraction of the pixel size) vertical to the CCD plane, shown in Fig.4(Schematic of vertical moving is the same).This method has two disadvantages. First, it is unsuitable for dynamic testing and can only be applied in the static image reconstruction. Second, because the pixel size is small (usually 5μm to 10μm) and the displacement should a fraction of this size (for example 2μm), it needs a moving table with high resolution and precision. Also it needs high stability in whole testing.In general, improvement of the spatial resolution of digital reconstruction is Fig.3 Relationship between object and CCDstill a big problem for the application of digital holography.5 Testing resultsFig.5 is the photo of the testing system. The paper does testing on two coins. The pixel size of the CCD is 4.65μm and there are 1 392×1 040 pixels. The firstis one Yuan coin of RMB (525 mm) used for image reconstruction by phase-shifting digital holography. The second is one Jiao coin of RMB (520 mm) for the testing of deformation measurement also by phase-shifting digital holography.5.1 Result of image reconstructionThe dimension of the one Yuancoin is 25 mm. The registrationdistance measured by ruler isabout 385mm. We capture ourphase-shifting holograms andreconstruct the image byphase-shifting digital holography.Fig.6 is the reconstructed image.Fig.7 is the curve of the auto-focusFig.4 Image capturing by moving CCD along horizontal directionFig.5 Photo of the testing systemfunction, from which we determine the real registration distance 370 mm. We can also change the controlling precision, for example 5mm, 0.1 mm,etc., to get more course or precision reconstruction position.5.2 Deformation measurementIn digital holography, the method of measuring deformation measurement differs from the traditional holography. It gets object wave before and after deformation and then subtract their phases to obtain the deformation. The study tested effect of heating deformation on the coin of one Jiao. The results are shown in Fig.8, Where (a) is the interferential signal of the object waves before and after deformation, and (b) is the wrapped phase difference.5.3 Improving the spatial resolutionFor the tested coin, we applied four sub-low-resolution holograms to reconstruct the high-resolution by the image-synthesizing technique. Fig.9 (a) is the reconstructed image by one low-resolution hologram, and (b) is the high-resolution image reconstructed from four low-resolution holograms.Fig.6 Reconstructed image Fig.7 Auto-focus functionFig.8 Heating deformation resultsFig.9 Comparing between the low and high resolution reconstructed image6 SummaryDigital holography can obtain phase and amplitude of the object wave at the same time. Compared to other techniques is a big advantage. Phase-shifting digital holography can realize image reconstruction and deformation with less noise. But it is unsuitable for dynamic testing. Applying the intensity sum of the reconstruction image as the auto-focusing function to evaluate the registering distance is easy, and computation is fast. Its precision is also sufficient. The image-synthesizing technique can improve spatial resolution of digital holography, but its static characteristic reduces its practicability. The limited dimension and too big pixel size are still the main obstacles for widely application of digital holography.外文文献译文：标题：图像重建中的相移数字全息摘要：相移数字全息术被用来研究研究艺术品的内部缺陷。

当一国的经济增长的可持续性岌岌可危的时候，金融业的改革一直被认为是提高资金使用效率和消费型经济增长重新走向平衡的必要（Lardy，1998年，Prasad，2007年）。
事实上，不久前，中国的国有银行被视为“技术上破产”，它们的生存需要依靠充裕的国家流动资金。
但是，在银行改革开展以来，最近，强劲的盈利能力已恢复到国有商业银行的水平。
但自从中国的国有银行在不久之前已经走上了改革的道路，它可能过早宣布银行业的改革尚未取得完全的胜利。
此外，其坚实的财务表现虽然强劲，但不可持续增长。
随着经济增长在2008年全球经济衰退得带动下已经开始软化，银行预计将在一个比以前更加困难的经济形势下探索。
本文的目的不是要评价银行业改革对银行业绩的影响，这在一个完整的信贷周期后更好解决。
相反，我们的目标是通过审查改革的进展和银行改革战略，并分析其近期改革后的强劲的财务表现，但是这不能完全从迄今所进行的改革努力分离。
本文有三个部分。
在第二节中，我们回顾了中国的大型国有银行改革的战略，以及其执行情况，这是中国银行业改革的主要目标。

Therefore, to improve a company's solvency Liabilities are on the rise。
On the other hand, the stronger a company’s solvency the easier cash investments required for the project，whose total assets are often relatively low debt ratio，which is the point of the pecking order theory of phase agreement. Similarly，a company's short—term liquidity，the stronger the short-term debt ratio is also lower, long—term solvency，the stronger the long—term debt ratio is also lower 。
Harris et al. Well, Eriotis etc. as well as empirical research and Underperformance found that the solvency （in the quick ratio and interest coverage ratio, respectively, short-term solvency and long—term solvency) to total debt ratio has significant negative correlation。

外文文献原稿和译文原稿The water level control circuit designWater source total ranks sixth in the world, per capita water resources is only a quarter of the world per capita consumption, and geographical distribution is very uneven, the vast region north of the Yangtze River, northin most parts of the medium-sized cities in the dry state, water shortage has become an important factor restricting China's economic development. Reasonable use of water resources has become an important issue for China is now facing. In order to achieve the rational use of water resources, in addition to in beefing water conservancy projects and enhance the people's awareness of water conservation efforts to improve. But more important is the application of new technical information, real-time to accurately understand and master a variety of hydrological information in order to make the right water scheduling and management, so that preventive measures to minimize water wastage . Coupled with long-standing water level measurement of water level has been an important issue in hydrology, water resources department. For the timely detection of the signs of the accident, precautionary measures in the future, economical and practical, reliable water level wireless monitoring systems will play a major role. The water level of dam safety, one of the important parameters for water drainage and irrigation scheduling, water storage, flood discharge.Provides a good foundation for the automation of monitoring, transmission and processing of the water level reservoir modernization. Need to monitor the water level in many areas of industrial and agricultural production. The site may not be able to close without the manpower to monitor, we can RMON, sitting in the control room facing the instrument can be monitored on-site, convenient and save manpower. In order to ensure the safe production of hydroelectric power station to improve power generation efficiency,Hydropower production process need to monitor the water level in the reservoir, trash rack, pressure drop and the tail water level. However, due to the different power plants with a different factual situations, have different technical requirements, and the measurement methods and location of the water level parameters and also the requirements of the monitoring equipment. This often results in the monitoring system equipment of a high degree of variety, interchangeability is not conducive to the maintenance of equipment will increase the equipment design, production, installation complexity. Therefore, on the basis of the actual situation and characteristics of the comprehensive study of hydropower water level monitoring, the use of modern electronic technology, especially single-chip technology and non-volatile memory technology, designed to develop a versatile, high reliability, easy maintenance, the applicable a variety of monitoring the environment, multi-mode automatic water level monitoring system has important practical significance. The subject according to the reservoir water level measurement needs, design a remote microcontroller water level monitoring system, the system automatically detects the water level, time processing, Data GPRS remote upload function. The design of the monitoring system will be significant savings in manpower and resources, low-power 24 hours of continuous monitoring and upload real-time control reservoir water level, to better adapt to the needs of the modern water level measurement, the safety of the dam reservoir, impoundment spillway to provide a basis.Microcontroller embedded microcontrollers are widely used in industrial measurement and control systems, intelligent instruments and household appliances. In real-time detection and automatic control of microcomputer application system, the microcontroller is often as a core component to use. The basic requirements of the water tower water level control system in the case of unattended automatic limit automatically start the motor to reach the water level in the water level in the water tower to the water tower water supply; water tower water level reached the water level upper limit is automatically off the motor to stop water supply. And unusual time to sound the alarm and troubleshooting in the water supply system at any time to ensure that the towers of the external normal water supply role. The water tower is often seen in daily life and industrial applications, water storage devices, external water supply through the control of its water level to meet the needs of its waterlevel control is universal. Regardless of socio-economic rapid water plays an important role in people's normal life and production. Once off the water, ranging from great inconvenience to the people's living standards, weight is likely to cause serious accidents and losses, and thus a higher demand of water supply system to meet the timely, accurate, safe and adequate water supply. If you still use the artificial way, the labor-intensive, low efficiency, safety is hard to guarantee the transformation of the automated control system, which must be carried out. In order to achieve sufficient amount of water, smooth water pressure, water towers, water level automatic control design low-cost, high practical value of the controller. The design uses a separate circuit to achieve high and low warning level processing, and automatic control, save energy, improve the quality of the water supply system.SCM is an integrated circuit chip, VLSI technology with data processing capability of the central processing unit CPU random access memory RAM, read only memory ROM, and a variety of I / O port and interrupt system, timers / timer other functions (which may also include a display driver circuit, pulse width modulation circuit, analog multi-channel converter, A / D converter and other circuit) integrated into a silicon constitute a small computer system. The basic features are as follows: the chip is small, but complete, SCM is one of the main features. Its internal program memory, data memory, a variety of interface circuit. Large processor speed is higher, the median more of the arithmetic unit, processing ability, but need to be configured in the external interface circuit; microcontroller clocked generally 100MHZ less suitable for small products for independent work, cited pin number from a few hundred. The application is simple, flexible, and free assembly language and C language development of SCM products. The working process of the microcontroller: microcontroller automatically complete the tasks entrusted to it, that is, single-chip implementation of the procedure for a section of the instruction execution process, the so-called directive requirements for single-chip implementation of the various operations used in the form of the command is to write down , which corresponds to a basic operation of designers assigned to it by the instruction set, an instruction; Full instructions can be executed by the microcontroller, the microcontroller instruction set, the different types of single-chip, and its instruction set is also different. So that the microcontroller canautomatically complete a specific task, the problem to be solved must be compiled into a series of instructions (these instructions must be selected microcontroller to the identification and implementation of the Directive), a collection of this series of instructions to become the program, the program need to pre- stored in the components - memory storage capabilities. Memory is composed by a number of storage units (the smallest unit of storage), like a large building has many rooms composed of the same, the instructions stored in these units, the instruction fetch unit and perform like the rooms of large buildings, each assigned to only a room number, each memory cell must be assigned to a unique address number, the address is known as the address of the storage unit, so as long as you know the address of the storage unit, you can find the storage unit that stores instructions can be removed, and then be executed. Programs are usually executed in the order, instruction program is a sequential storage, single-chip in the implementation of the program to be able to a section of these instructions out and be implemented, there must be a component to track the address of instruction where this part the program counter PC (included in the CPU), the start of program execution, endowed the address where the first instruction of the program to the PC, and then made for each command to be executed, the PC in the content will automatically increase, increase The amount is determined by the instruction length of this article may be 2 or 3, to point to the starting address of the next instruction to ensure the implementation of the instruction sequence.Microcontroller tower water level control system is the basic design requirements: inside the tower, we have designed a simple water level detection sensor used to detect the three water level, the low water level, the normal water level, water level. Low water to give a high single-chip, driven pumps and water, the red light; water level in the normal range, the pump add water, the green light; high water when the pump without water, the yellow light. The design process using the sensor technology, microcomputer technology, and light alarm technology and weak control the strong power of technology. Technical parameters and design tasks: 1, the use of the MCU to control the water level on the tower;, the water level in the water level detection sensor probe was the tower to give the microcontroller in order to achieve the water pump and water system and display system control; 3, the light alarm display system circuit, pumps and hydropower route relaycontrol;, analysis is drawn on the working principle of the system structure and a system block diagram using the microcontroller as a control chip, the main work process when the water in the tower low water level, water level detection sensor gave a high microcontroller, microcontroller-driven pump to add water and display system so that the red light lit; pump add water when the water level within the normal range, the green light, when the water level in the high-water mark, The microcontroller can not drive the water pump to add water, the yellow light. Light alarm circuit, the relay control circuit it works: When the water level in the low water, low water level detection sensor line is not +5 V power supply guide pass into the regulator circuit is treated in the output of the voltage regulator circuit has a high level, into the P1.0 port of the microcontroller, another high voltage circuit output of the microcontroller P1.1 port SCM After analysis, the P1.2 port outputs a low red light, drive, P1. 5 out a signal so that the optocoupler GDOUHE guide through so that the relay is closed, so that the water pump to add water; when the water level in the normal range, water pump plus P1.3 pin to a low level, so that the green light; when the water level in the high-water zone, the sensor of the two detection lines are conduction, are +5 power conduction into the SCM, SCM After analysis, the P1.4 pin out of a low yellow light, The optocoupler guide a low out of the P1.5-side can not pass, so that the relay can not be closed, the pump can not add water; failure when three flashing light indicates the system.译文水位控制电路设计中国水之源总量居世界第六位，人均占有水资源量仅为世界人均占有量的四分之一，并且在地域上分布很不平衡，长江以北的广大地区，特别是北方大、中城市大部分地区处于缺水状态，水资源短缺已成为制约我国经济发展的一个重要因素。

The paper goes on to review the literature on BPR. It explores the principles and assumptions behind reengineering, looks for commonfactors behind its successes or failures, examines case studies, and presents alternatives to "classical" reengineering theory. The paper pays particular attention to the role of information technology in BPR. In conclusion, the paper offers somespecific recommendations regarding reengineering. Old Wine in New Bottles The concept of reengineering traces its origins back to management theories developedas early as the nineteenth century. The purpose of reengineering is to "make all your processes the best-in-class." Frederick Taylor suggested in the 1880's that managers use process reengineering methods to discover the best processes for performing work, and that these processes be reengineered to optimize productivity. BPR echoes the classical belief that there is one best way to conduct tasks. In Taylor's time, technology did not allow large companies to design processes in across-functional or cross-departmental manner. Specialization was the state-of-theart method to improve efficiency given the technology of the time.（下略）之上之下各留一空行，宋体，三号字，居中，加粗。

The construction organization is an important technical and economic document for the project construction and guidance of project construction. Can adjust the contradiction of personnel, machinery, raw materials, environment, process, equq)ment9 civil construction, installation, management, production, etc. in construction. It is necessary to supervise and control the construction organization design so as to ensure the project quality with high quality, low cost, and lessEnergy consumption is conpleted.Key words: Project Management, Construction Organization, Program ImportanceConstruction organization design is the conception and specific arrangement of the entire construction process of the engineering construction project. It is the core and soul of the construction organization management work. Its purpose is to make the project faster, better quality, and more efficient. Make the whole project get relatively optimal results in the construction.1.The reason for the importance of the design of construction organizationThe construction project and its construction have three characteristics: fixed and fluidity, diversity and individuality, large body and long construction period. Therefore, the construction of each construction project must be carried out. This is because: The production of other general industrial products has its own fixed, long-term factory. The construction of the building is fluid, and it is impossible to establish such a factory. It is only when each construction project is constructed that a corresponding, temporary construction site preparation like thenature of the plant is employed・The unique features of construction and the characteristics of construction mobility determine that each construction project must select the appropriate equipment and labor organization. The selection of construction methods, the formulation of construction technology plans, and the organization of workforces and implements are collectively referred to as construction work capacity allocation. The characteristics of the construction cycle have determined that the supply of various labors, equq)ment and many materials and materials technologies will take a long time・ This will result in the construction and design of materials and technologies that are compatible with the overall construction schedule・From this we can see that construction organization design is very important in project management.2.The importance of construction organization designAs a product, building products play an extremely important role in project management throughout the construction process. The construction organization of the engineering construction project has a close relationship with its engineering cost. The basic contents of the construction organization design include:project overview and construction condition analysis, construction plan, construction process, construction schedule plan, and general plan of construction. There are also economic analysis and construction preparation work plans. Among them, the determination of the construction plan and construction process is more important. For examp le, the selection of construction machinery, the selection of horizontal transportation methods, the construction methods of the earthwork, the construction methods of the main structure and the selection of the construction technology all directly affect the project budget. The price changes・ Under the premise of guaranteeing project quality and satisfying the owners use requirements and construction period requirements, optimizing the construction plan and construction process is an important measure and method to control investment and reduce construction project cost2.1The construction organization plan affects the quality of the project to a great extent. Therefore, a reasonable project organization plan is not only the basis for ensuring the successful completion of the project, but also the basis for project safety. The construction organization design is an important part of theconstruction engineering design documents・ It is the main basis for prq)aring the project investment budget and the main reference for the preparation of bidding documents・ Therefore, careful construction of the construction organization will have a very important role in determining the project cost and reducing the investment in the project, which will help control the construction cost.2.2The construction organization plan is an important means for scientific management of construction activities. It has the dual role of strategic deployment and tactical arrangements・ It embodies the requirements for realizing the basic construction plan and design, provides the contents of the construction preparation work in each phase, and coordinates the mutual relations between each construction work area, each construction work type, and each voluntary work in the construction process. The construction organization plan must be able to determine the basic combination of various factors of production based on the characteristics and requirements of the engineering product and the current and possible winning construction conditions. It is impossible to carry out any production without effectively solvingthe problem・・3.Index calculation and analysis of construction organizationdesignAt present, what indicators should be established in the construction organization design are not uniform and the calculation method is not standardized・ As it is a yardstick for evaluating the overall effect of construction organization design and evaluation of implementation status, it is also the basis for examining the level and effect of production, operation and management of the unit (project department) that undertakes construction. We should pay attention to the following suggestions ・3. 1 indicator system. The index system should be set up to reflect the level reached by the construction organization's design goals and provide convenience for evaluation, assessment, and implementation.3. 2 Index calculations・(1) Construction preparation period.

英文参考文献原文专业：自动化姓名：张学超学号：120410116指导教师：王书强完成日期2016 年 4 月Integrated Substation Automation System AnalysisAbstractIn recent years, as computers and digital communication technology, secondary substation equipment is basically a computer-based. Computer protection, computer monitoring device in the substation have been widely used, which greatly raised the level of automation in power system reliability and operation, has achieved a lot of unmanned substations. However, due to differences in professional standards, different manufacturers used in the design of substation automation programs are not the same, thus leaving the majority of users at a loss.Substation relay protection, fault recorder, local and remote monitoring not only of different functions, and the realization of the principles and techniques are also different. Thus, the long-standing expertise in different technologies and the corresponding management departments. With the microprocessor-based protection, computer control and remote computer devices, such as widely used, it was noted that despite the different functions of these devices, the hardware configuration is the same, the collection and to control many of the same object. Thus, it appears from the overall situation to consider the idea of substation automation. However, in substation automation technologies, the implementation process of the relay, measure, control, remote features, as well as the relationship between them, are still some problems worthy of our study.Keywords: substation automationThe following currently used for many domestic substation automation design practical, from the secondary system analysis and comparison of several aspects.1 System structureThe whole system level by the station management, industrial bus network layer and spacing layer is composed of three parts, the system of all monitoring, protective equipment are modular units of the structural design, according to the voltage substation level, the size can be flexible and user requirements. Because of the centralized system is no longer used, it is no longer here, the following describes only the structure of distributed systems.1.1 Function-oriented distributed systemsA function of each unit completed, the system functions can be divided into: AC and DC measurement unit, remote acquisition unit, remote control and operation unit, pulse energy collection units, such as the protection unit. The advantages of such systems is the functional unit with the communication bus between the complete separation of the electrical, any fault on the system unit has no effect on the rest of the system. The disadvantage is that multi-screen group, the relative complexity of the second wiring, poor scalability, decentralized units can not be installed.1.2 Interval-oriented distributed systemPower transmission line to substation is divided into a number of intervals, such as into the line spacing, transformer spacing, round layout. Relatively independent of the spacing of equipment, only through the Internet communication network stations with station-level computers to communicate. Interval of each layer by telemetry, remote, remote control, the protection of the distribution of multi-CPU configuration, and the introduction of computers in the design of local area network technology, the distribution function, as far as possible the principle of decentralization, which, though greatly improved the reliability of, any interval failure will not affect the other partitions, but the reliability of each interval is relatively low, if any interval a fault will affect the whole interval.1.3 Object-Oriented Distributed SystemsThat is, a unit of an object into each line, each round, each transformer, capacitors can be targeted. This is a true full-distributed substation automation system, which broke the original limits of the functions of the second device, in accordance with the requirements of substation automation reorganization. This object-oriented distributed systems in line with the International Electrotechnical Commission's technical specifications, is the future direction of development. It has the following features: greatly improved system reliability, partial failure does not affect the system; relatively independent modules, each affected small; data sharing good; system efficiency; multi-function integrated control approach, making the operation of equipment management very simple, low maintenance; anti-interference ability; good scalability; stations needed the Second cable greatly reduced, saving investment.2 Dual-bus network and a single network structureStand-level management and monitoring layer to protect the data and commands between the transmission network can be double or single network structure. Hub for the 110kV substation, a dual network structure to facilitate a large flow of data to ensure rapid delivery when all kinds of signals, and to improve its reliability.Dual-network approach, usually an independent group to monitor and protect the network, in the transmission line or electrical equipment fault protection actions, the network can be used to protect the rapid transmission of recorded wave data. Substation 110kV and below, as a result of a smaller scale, data throughput, 110kV and below a single network substation can well meet the requirements of data transmission.3 integration of monitoring and protectionSince the technology level of the special status of protection and management system problems, long-term protection and monitoring has been separated. However, with the electricity sector, the gradual changes in management and computer and digital communication technology's rapid development, low-voltage level (eg, 35kV, 10kV) substation, in order to reduce the investment cost, ease of operation and management and improve the level of automation, control and protection of suitable integration unit, which is characterized by: monitoring and protection together to protect the independence of TA and TA to monitor access, this is to ensure the accuracy of measurements, but also improves the reliability. Hardware standardization, the same as the unit of hardware, software is different from the same template can be interchangeable, the measurement accuracy is not affected after the swap will help users maintain and master. Object-oriented design, a complete sampling. The main protection and back-up protection of a strict separation of the main transformer protection and high and low pressure side of the back-up protection is a small unit, and backup protection for each side of the design, the same unit within the strict separation of the protection of exports. Flexible configuration unit may focus on group screen, the installation can also be dispersed. There are configuration functions, a variety of ways to protect the flexibility to access and removal.This structure has not been widely used at present because of: the professional management of the current power grids are separated from the protection and remote, using this structure to change the management system, operation and maintenancepersonnel at the same time demands a higher level. Reliable operation of such systems is one of the keys to the hardware unit to monitor the protection must adapt to poor working conditions, need to have a strong anti-jamming, anti-vibration capabilities, able to adapt to high temperature and high humidity of the working environment; second is to have a efficient and reliable fast data communications networks. Due to the design of the reasons, the integration of monitoring the protection of unit failure, there is no monitoring and the protection of a clear interface, it is difficult to find and distinguish the scope of failure.4 RS485 or CAN field bus networkDistributed system of communication there are serial communication bus mode and network mode, which is the most typical RS485, the latter applies to more typical substation environment Controller Area Network CAN.4.1 RS485 busRS2485 bus used in earlier substation integrated automation system, is still used in many systems, its shortcomings are: For smaller systems, there is sufficient transmission rate, real-time guaranteed, but with the system expansion to quickly lower the system performance. And safety of anti-poor and usually only suitable for internal use in the control room, can not be used to switch and switch between games, that does not apply to the installation of decentralized distributed systems. From the structure of the network there can be only one master node, and the rest are from the node, the I / O unit must be horizontal communication station-level computers, the system poor flexibility. Data communication is in response to type the command, the node only after receiving the master node in order to respond to the order, a number of important changes on a timely bit of information is not sent, real-time low. Error Detection and Correction feature no. Communication protocol by the manufacturers own, different systems difficult to interconnect devices.4.2 CAN bus networkThe use of a short frame transmission, and each frame has CRC error checking and other measures, anti-interference ability, just the use of low-cost twisted-pair transmission can guarantee BER ≤ 10-11.Farthest away from direct communication network up to 10km, at this time for the transfer rate 5kbit / s, and when the transmission distance of 40m, the transfer rate of up to 1Mbit / s.By multi-master mode, a network node can be found in the office any time to the network to send messages to other nodes, but also by point-to-point,point-to-multipoint broadcasting and global transmission of information, flexible means of communication.Node on the network can be configured to different priority levels, and the use of non-destructive decision-bus technology, when there are two nodes at the same time to send information to the network, the low-priority node will send its own moratorium, but the high-priority nodes continue to send it will not be affected, thus greatly saving time bus ruling conflict in order to ensure real-time nature of the whole system.Abnormal nodes on a network, a self-closing function of the bus and cut off the node and bus links, to ensure that other operations will not be affected bus.CAN network technical specifications in line with ISO11898, has good hardware support and an open environment.5 operating system backgroundSystem platforms and network operating system there are two major categories of WindowsNT and SCOUNIX, each with its own advantages and disadvantages.5.1 WindowsNT operating systemUpward compatibility of hardware, and do not need to manually optimize the allocation of hardware.Support software, and portability, and easy expansion of the secondary development and function. There are all-round multi-functional configuration of the system configuration, including system configuration, graphics, reports, curve, such as incident handling, allowing the system to generate modified very fast, flexible and convenient; a variety of configurations to generate and output statements, all of Excel-based electronic statements, easy to manage and interface with other tools;standard large-scale data systems SQLServer or Sybase as the real-time and historical database, the system capacity to ensure the data integrity and consistency, and easy to maintain seamless connectivity with other systems.Intuitive interface, high universality, the user generally will be used to reduce the workload of training. The stability of the system slightly worse, and sometimes more prone to occur as a result of the mandate of Death. Security is not high, susceptible to the intrusion of computer viruses.

Unfortunately，there were very few efforts exploring the real-time communication and integration of BIM to the site and task conditions，and the interaction of BIM with the field crew.It is envisaged that Augmented Reality (AR) can fulfil this vision effectively through visualizing BIM right into the physical content of each construction activity or task.This paper discusses and investigates how BIM can be extended to the site via the "practical arm" of AR.Human factors are the core principle to investigate on，considering that AR，by nature，involves the human sensations with both real and virtual information sources.It is also found that AR should be ubiquitous and work together with accurate positioning technologies such as laser pointing. The framework also addresses how context-aware can be implemented in the integration of BIM andAR to achieve intelligent AR.Keywords-Building Information Modelling, Augmented Reality，Communication，llaboration，Visualization.I.INTRODUCTIONFroese has categorized trends in construction Information Communication and Technology (ICT) into three eras. The first era of construction ICT has been four decades and focused on developing stand-alone tools to assist specific work tasks such as CAD，structural analysis tools，estimating，etc.The second era (from the mid-1990s) of construction ICT has focused on computer-supported communications such as E-mail，the web，document management systems，etc.The third era of construction IT starting from one decade ago， f ocused on the potential for uniting all of these as a cohesive overall system through integration，BIM，etc. a major thrust of third era ICT ( typified by technologies such as BIM (Building Information Modelling)，IFCs，virtual design and construction ，and nD suggests fundamental changes to construction projects in which the project team comes together to produce comprehensive，computer-based，virtual prototypes of all aspects of the construction project as the central activity for the design and management of the project. Unfortunately，construction site activities are project-related and include site work planning，progress monitoring and management，tracking of material flows，procurement，quality management，and so on .The analysis has shown that this group of activities is not sufficiently supported by ICT tools .We therefore propose the fourth era of construction IT is incoming which is the era of ubiquitous decade where the digital project information (e.g.，BIM) generated prior to construction will be brought onto construction site and process in a fully digital and ubiquitous way.Site crews will be equipped with a full digital capability to access information right associated with the concerned construction component orentity. This paper presents the "BIM + AR" as a pioneering and innovative concept in the fourth era of construction ICT.Building Information Modelling (BIM) provides relatively static and pre-defined data and information.Augmented Reality (AR) provides onsite augmentation as well as onsite sensing considering vision-based AR can be a tracking tool as well.AR，as a class of easy-access interface，has the potential to change how site manager，construction workers，etc. interact and access to digital technical information in BIM.It is envisaged that Augmented Reality can fulfill this vision effectively through visualizing BIM data right into the physical context of each construction activity or task.Essentially the conventional role of AR is the visualization end.Any data fed into this end has to be pre-processed in a manner to make the data make sense to the end users.This paper discusses and investigates how BIM can be extended to the site via the "practical arm" of AR.In another word，AR can be the extended version of the BIM on site.II. BUILDI NG INFORMATION MODELLING (BIM)During the past decade，BIM concepts have been actively explored for expanding the usage into an nD environment .It is encouraging that this expansion is moving away from merely 3D modelling，towards more engineering analyses and various construction business functions . BIM has been applied in the areas of structure，energy，disaster prevention，construction planning and scheduling，project control，construction safety，and maintenance.In 2008，McGraw-Hili Construction conducted a survey with about 300 practitioners who involve BIM in their daily work. One of the major finding is that BIM has been used in a wide varieties of ways with diverse functions，however，surprisingly，only 18% use BIM for daily construction monitoring work of the management crew.Nothing has been done or even conceived to use BIM for construction site use that can guide the hands-on physical tasks of workers.Researchers have explored more active utilization of 3D models. Expanding the usage of BIM was further investigated by Taylor and Bernstein who focused on the patterns such as "visualization，coordination，analysis，and supply chain integration as a BIM trajectory". Naturally，BIM has to step out of the traditional functions in the digital world and enter into the physical outside construction site.AR is envisaged to become the media to convey BIM effectively into the construction site，as an invisible and extended hand of BIM.III. AUGMENTED REALITYAugmented Reality，is a technology or an environment where the additional information generated by a computer is inserted into the user's view of a real world scene. AR allows a user to work in a real world environment while visually receiving additional computer-generated or modeled information to support the task at hand.Augmented Reality environments have been applied primarily in scientific visualization and gaming entertainment in the past.The technological advancements of AR in the past decade have shown significant sophistication of technological capabilities. The AR concept and its associated enabling technologies have been migrating from marker-based method to markerless method (e.g.，D'Fusion)，recently to mobile context-aware method (e.g.，Layar and Wikitube)，which can bring AR into mobile and field context.Recent advances in computer interface design and hardware power have fostered certain number of noted recent AR research prototypes or test platforms in the arena of construction. More research，particularly regarding user issues，should support the technology development trend.More practical application domains of AR technology can be found in a thorough survey by Wang .IV. BIM+AR: PRACTICAL RATIONALE AND CASE ILLUSTRATIONSDesigning in BIM is one thing，and effectively building according to as planned is anotherthing.During construction，BIM information should drive the physical deliverables of the construction work. The discussion of the practical rationale and case illustrations for BIM+AR use in construction site focus on a few key areas relevant to construction site activities.The following sub-sections discuss the practical rationale and case illustrations for BIM+AR in the following key aspects relevant to construction site activities.• Interdependency• Link digital (paper) to physical• Synchronization of mental models for communication• Project control，monitoring，and feedback: as built v.s. as planned• Procurement: material flow tracking and management• From design to production: a visualization gap• Site plan and storageA. InterdependencyProject participants normally build up their individual mental models in their own minds to understand the project.In current practice，all project participants work with various sets of project information，which can be considered to be views of the overall project data set .A weakness of current on site project management practice is that it tends to treat typical construction work tasks as being far more independent than they actually are.Thus，each participant adopts a view that focuses primarily on their individual tasks，with any concern about these interdependencies addressed in a very reactive and incomplete way.BIM is capable of identifying these interdependence and complexity.There needs a powerful and proper visualization approach to supply such information to the on site workers who actually built everything，but not to increase the complexity of interdependences.AR can make the interdependencies between work tasks more explicit and also make the existing interdependencyand complexity more visible，and therefore more manageable onsite.Apparently AR is a promising tool to display any chosen single view or an integrated view right into the real view of participants，and right in place to the proposed location where the component should be built in a real-scale and real-time manner. The struggle to construct mental model can be alleviated by AR because models are visualized. For example，the execution of the resulting plan (e.g.，initiating work tasks)，and re-planning activities can all take place using AR. AR can be a proactive approach through which the potential negative impacts of any action can be identified earlier and mitigated or avoided more easily.As an example，spatial collision analysis (e.g.，between trades) is mainly conducted in the design stage with commercial 3D modeling systems，such as CA TIA and Navisworks. However，collisions still arise during the actual construction process due to the reasons such as the change of building elements，site facilities，and the movement of construction machinery. The challenge becomes how to figure out the on site real-time dynamic collision detection due to variations of construction sequence，schedule，components and methods and then provide support for project schema demonstration.Each specialty service involved in ductwork installation (e.g.，Heating Ventilation and Air Conditioning (HV AC) and electrical)，for example，works with a subset of project information that is relevant to their contractually agreed work.In addition，those involved erecting and installing the ductwork will be required to work in a sequence and so there is often a requirement to precede other works. While conflicts and clash detection can be largely identified in BIM during design，design changes and errors，or poor installation may lead to conflicts arising on-site. Thu s，using AR a site manager can address the potential for conflicts on-site by retrieving and visualize all the properties and details concerning the building elements from BIM (e.g.，Revit Mechanical Electrical and Plant (MEP)).Specific assembly instructions can also be linked to building elements and displayed ontothe workspace via AR. Everything can be visualized and planned in advance and any problem can be predictable. This is especially useful with ductwork installations to ensure for example，that working room is adequate to get plant into locations or to remove it.If it is predicted that the working room is not adequate，some critical element of plant needs to go before separating walls are put in place. This is especially relevant for off-site assemblies where the position of support steels or drop rods is critical to a preassembled element.AR can be used to set out where threaded rods are to go from the floor above，therefore reducing the danger of using a drill above the worker's head on an unstable temporary support structure.This can apparently improve speed，safety and accuracy as well as reducing the cost of supports.B. Link Digital (Paper) to PhysicalIndustrialization of the construction process requires a high level of automation，which happens to the site work tasks that require high integration of information and physical intensive resources.However，the effective integration of upstream information intensive resources as defined in BIM and their physical counterparts on site work is a challenge.All design and planning tasks work with information rather than physical resources. Designers，planners，and managers generally interact with the project through various information models，so their mental models are connected to the real-world project through various computer applications and documents.The computer applications used to support the various work tasks，and the documents (paper or electronic，including individual views presented by computer tools) that provide most of the information from which participants construct their mental models .This is the problem because site work requires not just working with information but also transforming physical resources to constructed facility.Much time is wasted because plans or drawings are misinterpreted，or the information is transferred imprecisely from the plan to the real object. There apparently needs an information bridge that can enable users to get away from informationand guide users better to link information with the physical resources in a more straightforward and effective way.For example，if the technical drawing indicates the installation of a specific drywall，the worker can immediately recognize where the drywall is located in the storage area and where it should be installed as the final place.Aforementioned，BIM+AR can provide integrated，computerbased collections of all known project information.BIM already contain geometric information non-geometric design and management information，such as material properties，supplier information，cost and schedule data，organizational information，etc. Those information can be readily visualized via AR，which can guide construction workers through the construction of actual buildings and improve the quality of their work.Certain plans may be more effectively comprehended by registering virtual models with objects in the real scene.It may be easier to build quickly and precisely as planned，especially complex designs in constrained spaces.C. Synchronization of Mental Models for CommunicationIt has been argued that information for building things in construction are from different resources and construction site stakeholders construct their own mental views of the project (derived from these single-perspective documents) with a low degree of integration between the views. For example，project manager looks at the overall scheduling and monitoring information and the workers look at the detailed work plan.AR can provide a common view for onsite communication，which can provide everyone with a unifying common perspective of the project information.Onsite communication and coordination can happen in a virtual resulting plan between different stakeholders on site prior to the immediate construction. In some sense，in terms of the coordination function of BIM，AR can be a site-version of BIM to carry out the real time of clash detection function onsite among different specialties，and even between the to-be-installed virtual components with existingcomponents in place.D. Project Control，Monitoring，and Feedback: As Built v.S. As PlannedSchedule conflict is one of major concerns in construction.Due to varied and complicated factors，the actual construction practice usually deviates largely from the plans in schedule overrun. Should the conflicts not resolved in a timely manner，the situation of behind-schedule will gradually accumulate to make schedule overrun more serious and even impact project quality and safety.The real world fully exhibits all of the interdependent changes as mentioned.The BIM models and technical documents currently used would be unlikely to reflect any of these interdependencies until they are manually updated by users.However，in most construction projects，changes are often made during the construction phase. Hence，the onsite output may have some variations from the initial design，which will need to be represented and recognised in the BIM model. Unfortunately，at present，there is no process in place of updating the designed model to incorporate the changes made during construction.Work tracing and analysis are available by comparing as planned and as built data on site. AR can tell the exact difference by visualizing the as-planned data onto the as-built environment. With AR，each building component can be allocated a status-identified，ordered，delivered，checked，installed，fixed，snagged，protected，and complete . It is then possible to indicate as-planned and as-built so that the progress of every element can be seen graphically. Being able to visually see the difference enables current and planned future progress to be monitored.It gives total visibility ensuring that mitigation can be made as soon as a gap between the planned and actual progress occurs.E. Procurement: Material Flow Tracking and ManagementTypically，prefabrication and construction processes run in parallel，which is why closecoordination between these two groups of activities is needed . In construction，costly delays can occur if the production plant does not provide enough building elements on time.It further makes on site material manipulation more complex and seriously affects other projects in a multi-project environment.In the process analysis，AR can significantly improve the overall performance.On-site status monitoring via AR and project documentation related activities could be consolidated and integrated with the pre-fabrication plant.This can improve efficiency of logistics，on-site material handling and overall project progress tracking.Transparency between construction works and pre-fabrication processes makes short-term planning more accurate，which leads to a shorter construction process with reduced delays and a lower demand for material buffering. Tracking of the status of building elements should cover both prefabrication processes and construction site works.AR can be used at the construction site to monitor the availability of building elements and to record the status of construction activities on the 3D model of the building. Status data on building elements can be exchanged between at the pre-fabrication plant and the construction site . Progress information on pre-fabrication processes and construction site processes is real-timely available to all project participants .Project planning，purchasing，production and logistics are typically handled by the ERP system in e-procurement.Building elements are tracked by the ERP until delivered to the construction site and BIM provides the mapping between the ERP and the actual components. AR visualizes the mapping relationship on the construction site.The extension of building element status information to construction site certainly contributes to the transparency of material flow tracking. Each building component can be allocated a status-identified，ordered，delivered，checked，installed，fixed，snagged，protected，and completed . This opens possibilities to automate material tracking with technologies like Radio-Frequency IdentificationTechnology (RFID) and also enables quick visualization of available and needed material at the site through Augmented Reality.The information is propagated from the ERP system(production factory) to BIM and becomes available to the site manager，who uses this information for the detailed planning of construction works.Such available BIM data can then be visualized onsite with AR.Such real-time evaluation will facilitate site manager for dynamic planning (plan the next step based on the information from the previous steps). On the other hand，the planned status of the building at a particular moment in time informs the production unit of the construction work dynamics and enables a better organization of production and a proactive material supply.An AR view of the onsite progress can be fed back to the workers at production site.F. From Design to Production: a Visualization GapThe interface between design and production has been a leitmotiv within construction. Traditionally，design is realised through the production of 2D shop drawings from a 3D object model. In the detailed design phase，most disciplines use their 3D object models as basis for the generation of the required 2D sections，plans and evaluations. The traditional method of having an index sheet and with a mass of drawings in the site offices that are 'thumbed through' to look at a specific detail is time a consuming and tedious process.Site workers think it is not necessary complications to have 3D model for site use and they can always refer to 2D technical drawing. The generation of 2D drawings from the 3D object models is challenging，even negatively impacting on the time schedules and on the resources needed and the process of generating (or extracting) 2D drawings is perceived as time-consuming and as one of the greatest challenges in the project.Additionally，another perceived challenge is the limited possibility to rapidly make 3D drawings for spontaneous needs and meetings. Therefore，a long-term approach to tackling these challenges could be to strive for a situationwhere the 3D object models replace the need for 2D.In the current practice，PDF is used，but they are all constrained in computers. Before the 3D images get to site，they are delivered to the client in PDF format enabling visual illustration of both the reinforcement and blocks of concrete in the project. BIM+AR can provide a full 3D interactive solid model of the design，giving the workers a visual understanding of details. Therefore a high level of constructability is achieved and conveyed clearly to the site via AR. The 3D reinforcement detailing reduces the periods of time usually required for alteration to drawings，saving time for all parties involved.In trusting the model checking time is significantly reduced. A full 3D solid model of concrete frame filled with rebar was produced with AR. This amounted to detailing reinforcement using 3D models issued to the design and site teams with each drawing. A 3D colour coded progress model was issued on a weekly basis to contractors. In BIM+AR，when a full model is created，drawings can be linked to the models so that people use the model to navigate and click on a location to find the drawings of an area. AR，used on a portable device.enables the user to click on a location in the 3D model and all the drawings related to that area.G. Site Layout and StorageThe BIM model can be used to identify storage areas for different sub-contractors and trades and to show how they need to change during the project. Larger items that are delivered such as stacks of bricks，plasterboard and steel need to be located in places that are well-ordered and clean. Trades people spend a considerable time on projects locating where material has been delivered or moved to. For instance，on multi-story projects，understanding how and when floors can be loaded out can reduce double or treble handling of materials which results in less damage to delivered materials. It has also been found to reduce waste and improve predictability as less material needs to be reordered，thrown away due to damage and less damaged material getsincorporated into works. AR can be a quicker and more accurate than the traditional site layout method that was labor intensive requiring a lot of re-measuring，especially when there is a misinterpretation of drawings or dimensions.By setting out bracket positions in this way they have made considerable savings in time and productivity.V. SUMMARYThis paper discusses and investigates how Building Information Modelling (BIM) can be extended to the site via the "hand" of AR. Human factors are the core principle to investigate on，considering that AR，by nature，involves the human sensations with both real and virtual information sources. The paper discusses several application promising areas where this concept of BIM+AR can be potentially applied to enhance information sharing，communication onsite in construction or other similar arenas. This paper will be a good guide and starting point for this entire new era of new ICT and also many new research topics can be derived and built upon from the theoretical work presented in this paper. Future work will include to prototype and develop BIM+AR systems for selected application scenarios.中文译文：BIM + AR：现场信息共享和通过高级可视化通信王祥玉教授，建筑环境学院科廷大学，珀斯，澳大利亚Xiangyu.wang@.au皮特艾迪.朗文特聘教授，建筑环境学院科廷大学，珀斯，澳大利亚plove@.au摘要越来越多的设计和施工人员在建筑，工程，施工（AEC）地区已经和正在使用建筑信息模型（BIM）。

外文文献原稿和译文原稿The introduction of the electronic commerceWith the rapid development of Internet, websites surging forward are after frying the foot " concept ", it is " practical " to all change direction one after another, and " practical one of the more distinct characteristics ": It is most websites that are all attempting to do the true " e-commerce ". What is " e-commerce " so? The so-called e-commerce (Electronic Commerce ) utilizes technology of the computer, network technology and long-range communication technology, realize the electrification , digitization and networked in the course of the whole commercial affair (buys and sells ). People are no longer face-to-face , look at the true goods , depend on the paper medium document (including the cash ) to carry on the business transaction. But provide and deliver system and fund convenient to be safe and settle account and do a deal systematically through a feast for the eyes goods information on net , perfect logistics through the network (buy and sell).In fact, the course of the whole trade can be divided into three stages:The first stage is information interchange stage: To trade company, in order to release information stage this stage. Mainly choose one's own outstanding goods , organize one's own goods information meticulously, set up one's own webpage, then join in famous websites with greater reputation , with stronger influence power , of higher clicking rate, let as many as possible people understand you know you. To buyer, this stage is the stage going to look for the goods and goods information on the net. It is mainly according to the needs of one's own one, surf the Net and look for the information and goods that oneself needs, and the trade company choosing the service with a high reputation to be well cheap.The second stage signs the contract stage of the goods: As B2B (trade company vs. trade company ), this stage is exchange course of signing the contract , finishing the essential trade and business note. The ones that should pay attention to are: Complicatedproblems , such as accuracy , dependability , can't be alteredding of the data ,etc.. As B2C (trade company vs. personal customer ), this stage finishes doing shopping the order form of the course signs course, the customer should refer goods , one's own contacting information , way , payment method to deliver goods which you choose to the trade company after in the network good sign well, the trade company should send mails or the telephone and verify above-mentioned contents after receiving the order form .The third stage carries on goods handing over , fund settlement stage according to the contract: This stage is stage when trade of the whole goods is very key, not merely involve the putting in place correctly and safely on the net of fund, involve the accuracy that the goods provide and deliver , put in place on time too at the same time . There is banking , provide and deliver systematic involvement at this stage, technically, in law, such respects as the standard is first-class have higher requests. The succeeding or not for a stage just here of online trade.The characteristics of developmentWider environment: People are not restricted by time , is not restricted by space , a great deal of restrictions not doing shopping by the tradition , can conclude the business on the net whenever and wherever possible .Wider market: This world will become very small on the net, a trade company can face global consumers , and a consumer can do shopping in any global trade company .Faster circulation and cheap price: E-commerce has reduce the intermediate link of circulation of commodities, has saved a large amount of expenses, thus reduced the cost of the circulation of commodities and trade greatly .Accord with the demands for times even more: People pursue the fashion , stress the individual character more and more nowadays, pay attention to the environment that does shopping, the online shopping, the shopping course that best reflects individualization. Influence1.E-commerce will change the way of the commercial activityThe traditional most typical scene of commercial activity is that " the salesman exists everywhere ", " the purchasing agent runs everywhere ", " reveal the mouth , run and break the leg ", consumers look for the goods that oneself need all pooped outlay in the market .Now, it is if touch it all right to pass Internet, people can enter the online market to browse through , purchase all kinds of products, and can also get online service , trade company can get in touch with the customer on the net , utilize the network to carry on the payment for goods and close serving, the government can also carry on electron calling for bid , government procurement ,etc. conveniently .2.E-commerce will change people's consumption patternThe biggest characteristic of online shopping is consumers' leading factor, do shopping the will is grasped in consumer's hands, at the same time consumers can also finish the trade by way of a kind of relaxed and free self-service , consumer's sovereignty can be fully embodied in the shopping at network.3.E-commerce will change the modes of production of enterprisesBecause e-commerce is a kind of swift , convenient shopping means, consumers' individualization , priviledges need and be able to be totally shown in front of the manufacturer through the network, in order to please customers, stress the design style of the products, a lot of enterprises in the manufacturing industry develop and popularize e-commerce one after another , if American Ford Motor Company connects with inside network of the company in 120,000 computer work stations in the whole world of March of 1998, and include 15,000 distributors of the whole world in the inside network , the final purpose of Ford Company is to realize being according to users' different requests, supply the automobile as required.4.E-commerce will bring a revolution to the traditional tradeE-commerce is in the course of the whole commercial activity, through the combination of people and telecommunications way , improve the efficiency of the commercial activity greatly, reduce the unnecessary intermediate link, the traditional manufacturing industry enters the eras of short run , much varieties by this, " zero stock " become possible; Traditional retail business and wholesale business open the new mode of " online marketing " of " having no shop "; Various kinds of online services have offered the brand-new method of service for service trade of the tradition.5.E-commerce will bring a brand-new financial circlesBecause pay the key link that is e-commerce by mails online, it is basic condition that e-commerce can be developed smoothly too, with the break-through of e-commerce on the electronic trade link, such services as online bank , bank card pay the network , electronic payment system of bank and electronic cheque , electronic cash, bring traditional financial circles into a brand-new field.6.E-commerce will change the government's behaviorThe government is undertaking the function of the management and service of a large number of societies , economy , culture, in e-commerce era, as enterprises use e-commerce to carry on the production and management, the bank computerizes financial services, and while consumers realize cosumption online, will put forward the new request , an electronic government or calling the online government for government's administration behaviour too, will become an important social role as e-commerce is developed.In a word, as a kind of commercial activity course, e-commerce will bring an unprecedented revolution, its impact on social economy far exceeds the commercial affair itself. Besides these above-mentioned influence, it will also bring enormous influence on employment , legal system and culture and education ,etc., e-commerce will bring the mankind into the information-intensive society .In the modern information-intensive society, e-commerce can enable mastering the enterprises and individuals of the information technology and business rule , utilizing various kinds of electronic tools and networks systematically, the low cost with high efficiency is engaged in various kinds of commercial trade activities realized in electronic way. According to using with the function , can divide e-commerce into three levels or 3S , namely SHOW , SALE , SERVE:1.SHOW (show)Offer the electronic market conditions, enterprises release goods and other information on the net by way of webpage, with advertise etc. on the net, through SHOW, enterprises can establish one's own corporate image , expand the popularity of enterprises, propagate the service of one's own products , look for the new trade cooperative partner.2.SALE (trade)Realize the whole course of the transaction activity of the traditional form in electronic way in the network, for instance online shopping ,etc.. Enterprises can finish the whole course of the trade through SALE, expand the range traded, improve the efficiency of the work , reduce the cost of the trade , thus obtain the economic and social benefit.3.SERVE (serve)And the service after sale before meaning various kinds of related to commercial activity that enterprises launch through the network and selling, through such SERVE on net, enterprises can perfect one's own e-commerce system , consolidate the already existing customer , attract the new customer , thus expand the management business of enterprises, obtain greater economic benefits and social benefit. The enterprise is a protagonist who launches e-commerce.KindsE-commerce inside enterprise is mainly to deal with and exchange trade and business information through the way of the network (Intranet ) inside enterprises. The network (Intranet ) is a kind of effective commercial tool inside enterprises, pass the fire wall , enterprises isolate one's own inside network from Internet, it can be used for automaticallying process the commercial affair to operate and work to flow, strengthen it to the access of important system and key data, share experience , solve customer's problem together, and keep the connection while organizing. E-commerce inside enterprises, can bring the following advantage to enterprise : Increase agility that commercial activity punish, to market situation can reacting quickly, can provide service for the customer better . E-commerce (B-B mode ) among enterprise and enterprise mainly carries on the electronic commercial activity through INTERNET or the special-purpose network way. E-commerce among enterprises is merits attention and probes into most three kinds of modes of e-commerce, because it has potentiality of development most.E-commerce (B-C mode ) between enterprise and consumer is mainly that enterprises offer a new-type shopping environment to consumer through INTERNET --The online shop, consumers do shopping on the net through the network , pay on the net. Because this kind of mode has saved customer and time and space of both sides of enterprise, have improve trade efficiency greatly, has saved the unnecessary expenses.Enterprise and inter-governmental e-commerce (B-G mode) the commercial activity cover enterprise and government organize every thing among, mainly including government procurement , declare at the Customs , declare dutiable goods etc.on the net.译文电子商务介绍随着因特网的迅速发展，风起云涌的网站在炒足了“概念”之后，都纷纷转向了“务实”，而“务实”比较鲜明的特点之一：是绝大多数的网站都在试图做实实在在的“电子商务”。

这篇演说震惊了西方整个学术界，这不仅因为舒尔茨一向给人的印象是一位农业经济学家，而且还因为一般人总以为资本是有形的、物质的，至于教育、在职训练、保健、人口流动等方面的投资也可以增加一国资本存量和加速经济发展的观念对于当时的经济学界来说的确是很新鲜的。
这次会议之后，人力资本成为经济学中一个非常热门的新兴领域，“人力资本”也成了西方教育经济学的基本概念，人力资本理论成为现代西方资产阶级发展经济学的一个主要学派。
《人力资本投资》---- 内容提要舒尔茨这篇《人力资本投资》被人称之为：人力资本研究新领域的“独立宣言”，其在文中提出了九项主张：“在税收政策上应该给人力资本给予优惠；防止人人力资本的闲置和老化；避免对人力资本投资进行人为的干扰；完善人力资本市场，银行应积极主动地提供人力资本所需的费用，鼓励私人和公共投资；政府应承担人力资本投资的大部分费用，特别是资助劳动力向城市转移；重视低收入者的人力资本投资；明确教育和保健同样具有经济意义，它们是一项投资，要扭转投资在这方面的不平衡；增加政府投入、扩大人力资本投资，以减少收入的不平等；舒尔茨所提出的人力资本理论的基本内涵是：把资本分为物质资本和人力资本两种形式。
人力资本是体现在劳动者身上的以劳动者的数量和质量表示的资本。
劳动者的知识、技术水平、劳动技能的高低不同，决定了人力资本对经济的生产性作用的不同，结果使国民收入增长的程度也不同。
舒尔茨的人力资本理论有五个主要观点：（一）人力资本存在于人的身上，表现为知识、技能、体力（健康状况）价值的总和。
一个国家的人力资本可以通过劳动者的数量、质量以及劳动时间来度量。

外文文献（一）原文DUAL FULL BRIDGE PROTECTED MOTOR DRIVER（A3976）The A3976 is designed to drive both windings of a bipolar stepper motor or bidirectionally control two DC Motors. Both H-Bridges are capable of continuous output currents of up to+/- 500 mA and operating voltages to 30V. Free wheeling, substrate isolated diodes are included for output transient suppression when switching motors or other inductive loads. For each bridge the PHASE input controls load current polarity by selecting the appropriate source and sink driver pair. The ENABLE input, when held high, enables the respective output H-bridge. When both ENABLE pins are held low the device will enter SLEEP mode and consume less than 100mA. The 3976 is protected to ensure safe operation in harsh operating environments and was designed specifically for automotive applications. Protection circuitry will check for open or shorted load, motor lead short to ground or supply, VBB overvoltage, VCC undervoltage, and thermal shutdown. If any of these conditions are detected the outputs will be disabled and fault information will be output to diagnostic pins FAULT1 and FAULT2. The 3976 is supplied in a choice of two power packages, a 16-lead plastic DIP with a copper batwing tab (suffix ‘B’), and a 24-lead plastic SOIC with a copper batwing tab (suffix ‘LB’). In both cases, the power tab is at ground potential and needs no electrical isolation.FEATURES（1）30 V , ±500 mA Continuous Output Rating（2）35V Load Dump Survival（3）Output Short Circuit Protection（4）Coded Fault Diagnostic Outputs（5）Low Current Standby Mode（6）Open Load Monitor（7）Low Current Standby Mode（8）VBB Over Voltage Shutdown（9）Internal Thermal Shutdown Circuitry（10）Internal Low Parasitic Free Wheeling Diodes（11）Crossover Current ProtectionABSOLUTE MAXIMUM RATINGSat TA = +25°COperating Supply Voltage, VBB .................... 30 VNon-Operating Supply Voltage..................... 35 V Output Current, IOUT ............................±500 mA* Logic Supply Voltage, VCC.......................... 7.0 V Fault Output Voltage ................................... 7.0 VLogic Input Voltage Range, VIN.......................... -0.3 V to VCC + 0.3 VPackage Power Dissipation (TA = +25°C), PDA3976KLB..................................2.2 WA3976KB ....................................2.9 WOperating Temperature Range,TA ..............................-40°C to +125°CJunction Temperature, TJ .........................+150°C Storage Temperature Range, TS...............................-55°C to +150°C* Output current rating may be limited by duty cycle, ambient temperature, and heat sinking.

During normal PWM operation diagnostic circuitry will look for a minimum source current level after a bridge is signalled on. Additionally, the diode flyback is monitored on the proper output. The logic will signal a fault and disable the outputs if it determines that the current is below the minimum level AND no flyback is occurring. If the inductive load is too large, the current would take too long to reach the minimal level and afalse open load would be reported. It is recommended that the inductive load be less than38mH.Short Circuit Protection. Internal sense resistors in series with VBB and ground willtrip the fault circuitry if greater than 1.1A is detected. To prevent false overcurrent events due to reverse recovery spikes of the clamp diodes, the current monitor is blanked for 5us after a high side is signalled to turn on. If an additional input command follows after the initial fault, the selected pair of drivers will pulse on for the 5us blanking duration. The short circuit fault will remember the input state where the fault occurred and will wait for that particular logic state after the short has been removed before normal operation is allowed to resume.Thermal Protection. Circuitry turns OFF all drivers when the junction temperaturereaches 170°C typically. It is intended only to protect the device from failures due to excessive junction temperatures and has a hysteresis of approximately 15°C.Layout. The printed wiring board should use a heavy ground plane. For optimum electricaland thermal performance, the driver should be soldered directly onto the board. The load supply pin, VBB, should be decoupled with an electrolytic capacitor (> 47 μF is recommended) placed as close to the device as possibleEnengy or Solar EnegryEnergy means the power which does work and drives machines. All living things (including humans) rely on the sun as a source of energy. Coal, petroleum, and natural gas are energy sources available today because organisms in the past captured sunlight energy and stored it in the complex organic molecules that made up their bodies, which were then compressed and concentrated. With the development of society, a large of energy sources have been used,such as coal, petroleum, natural gas, geothermal energy, nuclear fission power, nuclear fusion power, solar energy, and Hydrogen gas. however, under the circumstances, the quantity of energy source is limited. unlimited usage of energy source results in energy crisis. At present, most of the energy consumed by humans is produced from fossil fuels. The greatest recoverable fossil is in the form of coal and lignite. Although world coal resources are enomous and potentially can fill energy needs for a century or two, their utilization is limited by environmental disruption from mining and emissions of carbon dioxide and sulfur dioxide. These would become intolerable long before coal resources were exhausted. Only a small percentage of coal and lignite has been utilized to date, whereas much of the recoverable petroleum and natural gas has already been consumed. Petroleum has several characteristics that make it superior to coal as a source of energy. Its extraction causes less environmental damage than does coal mining. It is a more concentrated source of energy than coal, and it burns with less pollution, and it can be moved easily through pipes. These characteristics make it an ideal fuel for automobiles.Since first commercial oil well in 1859, somewhat more than 100 million barrels of oil have been produced in the United States, most of it in recent years. In 1990 world petroleumconsumption was at a rate of about 65 million barrels per day. Projected use of petroleum and natural gas indicates rapid depletion. Alaskan oil can help the petroleum supply only temporarily. Peak world petroleum resources production will be reached within a few years. Since the first "energy crisis" of 1973-1974, some concrete actions have even taken place. However, the several-fold increase in crude oil prices since 1973 has extacted a toll. In the U.S. and other industrialized nations, the economy has been plagued by inflation, recession, unemployment, and obsolescence of industrial equipment. The economies of some petroleum-deficient developing countries have been devastated by energy prices.Energy crisis was accompanied by worldwide shortages of some foods and minerals, followed in some cases by surpluses, such as the surplus wheat resulting from increased planting and a copper surplus resulting from the efforts of copper-producing nations to acpuire foreign currency by copper export.As known to all,the availability and cost of energy has become dominant factors in society today. Obviously, solving the "energy crisis" makes good sense. Many schemes has been proposed for conserving present energy resources and for developing new ones. It is always possible to use less energy in any process. Therefore, energy engineer is created and developed. The first goal of energy engineer is to determine the methods by which energy utilization is reduced but the output remains the same, or even increases.The second goal is to determine which methods of using less energy are cost effective.Conventional engineering techniques are used to evaluated the mechanisms of energy use. Economic considerations are of equal importance and life cycle cost and saving techniques are used to determine cost-effective measures. The evaluation focuses on those uses which are significant in the overall picture and attempts to determine those technical measures that can reduce usage and save money.Meanwhile, looking for ideal energy sources is also very important to solve energy crisis. The recipe for an ideal energy source calls for one that is unlimited in supply, widely available, and inexpensive; it should not add to the earth's total heat burden or produce chemical air and water pollutants. Solar energy fulfills all of these criteria. Solar energy does not add excess heat to that which must be radiated from the earth. On a global basis, utilization of only a small fraction of solar energy reaching the earth could provide for all energy needs.Solar energy is unlimited in supply, but its exploitation and utilization are limited owing to the limitation of technology and conditions. Solar energy utilization needs an enormous amount of land, and there are economic and environmental problems related to the use of even a fraction of this amount of land for solar energy collection. Certainly, many residents of Arizona would not be pleased at having so much of the state devoted to solar collectors, and some environmental groups would protest the resultant shading of rattlesnake habitat. Solar power cells for the direct conversion of sunlight to electricity have been developed and are widely used for energy in space vehicles. With present technology, however, they remain too expensive for large-scale generation of electricity. Therefore, most schemes for the utilization of solar power depend upon the collection of thermal energy, followed by conversion to electrical energy. The simplest such approach involves focusing sunlight on a steam-generating bioler. Parabolic refkectors can be used to focus sunlight on pipescontaining heat-transporting fluids. Selective coatings on these pipes can be used so that only a small percentage of incident energy is reradiated from the pipes.（二）翻译全双桥电机保护驱动器（A3976）A3759是一种用来驱动双极性步进电机双绕组的单片集成电路，也可以用来双向控制两台电动机。

Criminal Law1.General IntroductionCriminal law is the body of the law that defines criminal offenses, regulates the apprehension, charging, and trial of suspected offenders,and fixes punishment for convicted persons. Substantive criminal law defines particular crimes, and procedural law establishes rules for the prosecution of crime. In a democratic society, it is the function of the legislative bodies to decide what behavior will be made criminal and what penalties will be attached to violations of the law.Capital punishment may be imposed in some jurisdictions for the most serious crimes. And physical or corporal punishment may still be imposed such as whipping or caning, although these punishments are prohibited in much of the world. A convict may be incarcerated in prison or jail and the length of incarceration may vary from a day to life.Criminal law is a reflection of the society that produce it. In an Islamic theocracy, such as Iran, criminal law will reflect the religious teachings of the Koran; in an Catholic country, it will reflect the tenets of Catholicism. In addition, criminal law will change to reflect changes in society, especially attitude changes. For instance, use of marijuana was once considered a serious crime with harsh penalties, whereas today the penalties in most states are relatively light. As severity of the penaltieswas reduced. As a society advances, its judgments about crime and punishment change.2.Elements of a CrimeObviously, different crimes require different behaviors, but there are common elements necessary for proving all crimes. First, the prohibited behavior designated as a crime must be clearly defined so that a reasonable person can be forewarned that engaging in that behavior is illegal. Second, the accused must be shown to have possessed the requisite intent to commit the crime. Third, the state must prove causation. Finally, the state must prove beyond a reasonable doubt that the defendant committed the crime.(1) actus reusThe first element of crime is the actus reus.Actus is an act or action and reus is a person judicially accused of a crime. Therefore, actus reus is literally the action of a person accused of a crime. A criminal statute must clearly define exactly what act is deemed “guilty”---that is, the exact behavior that is being prohibited. That is done so that all persons are put on notice that if they perform the guilty act, they will be liable for criminal punishment. Unless the actus reus is clearly defined, one might not know whether or not on e’s behavior is illegal.Actus reus may be accomplished by an action, by threat of action,or exceptionally, by an omission to act, which is a legal duty to act. For example, the act of Cain striking Abel might suffice, or a parent’s failure to give to a young child also may provide the actus reus for a crime.Where the actus reus is a failure to act, there must be a duty of care. A duty can arise through contract, a voluntary undertaking, a blood relation, and occasionally through one’s official position. Duty also can arise from one’s own creation of a dangerous situation.(2)mens reaA second element of a crime is mens rea. Mens rea refers to an individual’s state of mind when a crime is committed. While actus reus is proven by physical or eyewitness evidence, mens rea is more difficult to ascertain. The jury must determine for itself whether the accused had the necessary intent to commit the act.A lower threshold of mens rea is satisfied when a defendant recognizes an act is dangerous but decides to commit it anyway. This is recklessness. For instance, if Cain tears a gas meter from a wall, and knows this will let flammable gas escape into a neighbor’s house, he could be liable for poisoning. Courts often consider whether the actor did recognise the danger, or alternatively ought to have recognized a danger (though he did not) is tantamount to erasing intent as a requirement. In this way, the importance of mens rea hasbeen reduced in some areas of the criminal law.Wrongfulness of intent also may vary the seriousness of an offense. A killing committed with specific intent to kill or with conscious recognition that death or serious bodily harm will result, would be murder, whereas a killing affected by reckless acts lacking such a consciousness could be manslaughter.(3)CausationThe next element is causation. Often the phrase “but for”is used to determine whether causation has occurred. For example, we might say “Cain caused Abel”, by which we really mean “Cain caused Abel’s death. ”In other words, ‘but for Cain’s act, Abel would still be alive.” Causation, then, means “but for” the actions of A, B would not have been harmed. In criminal law, causation is an element that must be proven beyond a reasonable doubt.(4) Proof beyond a Reasonable DoubtIn view of the fact that in criminal cases we are dealing with the life and liberty of the accused person, as well as the stigma accompanying conviction, the legal system places strong limits on the power of the state to convict a person of a crime. Criminal defendants are presumed innocent. The state must overcome this presumption of innocence by proving every element of the offense charged against the defendant beyond a reasonable doubt to thesatisfaction of all the jurors. This requirement is the primary way our system minimizes the risk of convicting an innocent person.The state must prove its case within a framework of procedural safeguards that are designed to protect the accused. The state’s failure to prove any material element of its case results in the accused being acquitted or found not guilty, even though he or she may actually have committed the crime charged.3. Strict LiabilityIn modern society, some crimes require no more mens rea, and they are known as strict liability offenses. For in stance, under the Road Traffic Act 1988 it is a strict liability offence to drive a vehicle with an alcohol concentration above the prescribed limit.Strict liability can be described as criminal or civil liability notwithstanding the lack mens rea or intent by the defendant. Not all crimes require specific intent, and the threshold of culpability required may be reduced. For example, it might be sufficient to show that a defendant acted negligently, rather than intentionally or recklessly.1. 概述刑法是规定什么试犯罪，有关犯罪嫌疑人之逮捕、起诉及审判，及对已决犯处以何种刑罚的部门法。

HechtInterest is growing in modifying national income accounting systems to promote understanding of the links between economy and environment.The field of environmental accounting has made great strides in the past two decades, moving from a rather arcane endeavor to one tested in dozens of countries and well established in a few. But the idea that nations might integrate the economic role of the environment into their income accounts is neither a quick sell nor a quick process; it has been under discussion since the 1960s. Despite the difficulties and controversies described in this article, however, interest is growing in modifying national income accounting systems to promote understanding of the links between economy and environment.Environmental accounting is underway in several dozen countries, where bureaucrats, statisticians, and other proponents both foreign and domestic have initiated activities over the past few decades. Several countries have made continuous investments in building routine data systems, which are integrated into existing statistical systems and economic planning activities. Others have made more limited efforts to calculate a few indicators, or analyze a single sector. Some of the earliest research on environmental accounting was done at RFF by Henry Peskin, working on the design of accounts for the United States.One of the first countries to build environmental accounts is Norway, which began collecting data on energy sources, fisheries, forests, and minerals in the 1970s to address resource scarcity. Over time, the Norwegians have expanded their accounts to include data on air pollutant emissions. Their accounts feed into a model of the national economy, which policymakers use to assess the energy implications of alternate growth strategies. Inclusion of these data also allows them to anticipate the impacts of different growth patterns on compliance with international conventions on pollutant emissions.More recently, a number of resource-dependent countries have become interested in measuring depreciation of their natural assets and adjusting their GDPs environmentally. One impetus for their interest was the 1989 study “Wasting Assets: Natural Resources in the National Income Accounts,” in which Robert Repetto and his colleagues at the World Resources Institute estimated the depreciation of Indonesia’s forests, petroleum reserves, and soil assets. Once adjusted to account for that depreciation, Indonesia’s GDP and growth rates both sank significantly below conventional figures. While “Wasting Assets” called many to action, it also operated as a brake, leading many economists and statisticians to warn against a focus on green GDP, because it tells decision makers nothing about the causes or solutions for environmental problems.Since that time, several developing countries have made long-term commitments to broad-based environmental accounting. Namibia began work on resource accounts in 1994, addressing such questions as whether the government has been able tocapture rents from the minerals and fisheries sectors, how to allocate scarce water supplies, and how rangeland degradation affects the value of livestock.The Philippines began work on environmental accounts in 1990. The approach used there is to build all economic inputs and outputs into the accounts, including non marketed goods and services of the environment. Thus Filipinos estimate monetary values for such items as gathered fuel wood and the waste disposal services provided by air, water, and land; they then add in direct consumption of such services as recreation and aesthetic appreciation of the natural world. While their methodology is controversial, these accounts have provided Philippine government agencies and researchers with a rich array of data for policymaking and analysis.The United States has not been a leader in the environmental accounting arena. At the start of the Clinton administration, the Bureau of Economic Analysis (BEA) made a foray into environmental accounting in the minerals sector, but this preliminary attempt became embroiled in political controversy and faced opposition from the minerals industry. Congress then asked the National Research Council (NRC) to form a blue ribbon panel to consider what the nation should do in the way of environmental accounting. Since then, Congressional appropriations to BEA have been accompanied by an explicit prohibition on environmental accounting work. The ban may be lifted, however, once the recommendations of the NRC study are made public.How environmental accounting is being done varies in a number of respects, notably the magnitude of the investment required, the objectivity of the data, the ability to compare different kinds of environmental impacts, and the kinds of policy purposes to which they may be applied. Here are some of the methods currently in u se.Natural Resource Accounts. These include data on stocks of natural resources and changes in them caused by either natural processes or human use. Such accounts typically cover agricultural land, fisheries, forests, minerals and petroleum, and water. In some countries, the accounts also include monetary data on the value of such resources. But attempts at valuation raise significant technical difficulties. It is fairly easy to track the value of resource flows when the goods are sold in markets, as in the case of timber and fish. Valuing changes in the stocks, however, is more difficult because they could be the result either of a physical change in the resource or of a fluctuation in market price.Green GDP. Developing a gross domestic product that includes the environment is also a matter of controversy. Most people actively involved in building environmental accounts minimize its importance. Because environmental accounting methods are not standardized, a green GDP can have a different meaning in each project that calculates it, so values are not comparable across countries. Moreover, while a green GDP can draw attention to policy problems, it is not useful for figuring out how to resolve them. Nevertheless, most accounting projects that include monetary values do calculate this indicator. Great interest in it exists despite its limitations.Environmental accounting would receive a substantial boost if an international consensus could be reached on methodology. The UN Statistics Department has coordinated some of the ongoing efforts toward this end since the 1980s. In 1993, theUN published the System for Integrated Economic and Environmental Accounting (SEEA) as an annex to the 1993 revisions of the SNA. SEEA is structured as a series of methodological options, which include most of the different accounting activities described above; users choose the options most appropriate to their needs.No consensus exists on the various methods that the UN recommended. In fact, SEEA is now undergoing revision by the so-called “London Group,” comprised primarily of national income accountants and statisticians from OECD countries. The group’s work will be an important step toward con sensus on accounting methods, but the process will be lengthy: Development of the conventional SNA took some forty years.A number of steps can be taken now toward the goal of ensuring that environmental accounting is as well established as the SNA. First, information must circulate freely about existing environmental accounts and how they are contributing to economic and environmental policy. Ongoing work needs to be identified and systematically reviewed and analyzed to learn lessons, which may inform the design and implementation of future accounting activities. The Green Accounting Initiative of the World Conservation Union has embarked on this effort, and a number of other organizations are calling for similar activities. Use of the World Wide Web may facilitate access to unpublished work, although it will require a concerted effort to obtain accounting reports and seek permission to load them on the Internet.Second, development of a core of internationally standardized methods will contribute to willingness to adopt environmental accounting. Experts in the field—including economists, environmentalists, academics, and others outside of the national statistical offices—should take a proactive role in tracking the work of the London Group and insist that the standard- setting process involve participants representing a spectrum of viewpoints, countries, and interested stakeholders. An opportunity exists for research institutes to take a lead in identifying the financial resources needed to facilitate a broader standard setting process, and to elicit a full range of voices to build a consensus on methodology.Finally, and perhaps most importantly, the more countries institutionalize construction of environmental accounts, the greater the momentum for more of the same.Still, building accounts—like developing any time series statistics—will not happen overnight. Their construction will require sustained institutional and financial commitment to ensure that the investment lasts long enough to yield results. But the experiences of Norway, Namibia, and the Philippines show that such a commitment can pay off; it is a commitment that more countries around the world need to make.环境会计by Joy E.

这篇演说震惊了西方整个学术界，这不仅因为舒尔茨一向给人的印象是一位农业经济学家，而且还因为一般人总以为资本是有形的、物质的，至于教育、在职训练、保健、人口流动等方面的投资也可以增加一国资本存量和加速经济发展的观念对于当时的经济学界来说的确是很新鲜的。
这次会议之后，人力资本成为经济学中一个非常热门的新兴领域，“人力资本”也成了西方教育经济学的基本概念，人力资本理论成为现代西方资产阶级发展经济学的一个主要学派。
《人力资本投资》---- 内容提要舒尔茨这篇《人力资本投资》被人称之为：人力资本研究新领域的“独立宣言”，其在文中提出了九项主张：“在税收政策上应该给人力资本给予优惠；防止人人力资本的闲置和老化；避免对人力资本投资进行人为的干扰；完善人力资本市场，银行应积极主动地提供人力资本所需的费用，鼓励私人和公共投资；政府应承担人力资本投资的大部分费用，特别是资助劳动力向城市转移；重视低收入者的人力资本投资；明确教育和保健同样具有经济意义，它们是一项投资，要扭转投资在这方面的不平衡；增加政府投入、扩大人力资本投资，以减少收入的不平等；舒尔茨所提出的人力资本理论的基本内涵是：把资本分为物质资本和人力资本两种形式。
人力资本是体现在劳动者身上的以劳动者的数量和质量表示的资本。
劳动者的知识、技术水平、劳动技能的高低不同，决定了人力资本对经济的生产性作用的不同，结果使国民收入增长的程度也不同。
舒尔茨的人力资本理论有五个主要观点：（一）人力资本存在于人的身上，表现为知识、技能、体力（健康状况）价值的总和。
一个国家的人力资本可以通过劳动者的数量、质量以及劳动时间来度量。
（二）人力资本是投资形成的。
投资渠道有五种，包括营养及医疗保健费用、学校教育费用、在职人员培训费用，择业过程中所发生的人事成本和迁徙费用。
（三）人力资本投资是经济增长的主要源泉。
舒尔茨说，人力投资的增长无疑已经明显地提高了投入经济奋飞过程中的工作质量，这些质量上的改进也已成为经济增长的一个重要的源泉。
有能力的人民是现代经济丰裕的关键。
（四）人力资本投资是效益最佳的投资。
人力投资的目的是为了获得收益。
舒尔茨对1929--1957年美国教育投资对经济增长的关系作了定量研究，得出如下结论：各级教育投资的平均收益率为17％；教育投资增长的收益占劳动收入增长的比重为70％；教育投资增长的收益占国民收入增长的比重为33％。
也就是说，人力资本投资是回投率最高的投资。
（五）人力资本投资的消费部分的实质是耐用性的，甚至比物质的耐用性消费品更加经久耐用。
1、外文文献原文《Human capital investment》excerptAuthor: Theodore W. Schultz《Human capital investment》Brief introduction "Human capital investment" in a speech entitled Schultz 1960 annual meeting of the American Economic Association, the human capital point of view made for a very systematic exposition. This speech shocked the whole of Western academia, not only because Schultz has always given the impression that an agricultural economist, but also because most people think the capital is tangible, material, as for education, job training, health care investment, migration and other aspects can also increase a country's capital stock and accelerate economic development concept for the prevailing economic circles is indeed very fresh. Following this meeting, the human capital to become a very popular economicsemerging field of "human capital" Western education has become the basic concepts of economics, human capital theory as a major school of modern Western bourgeois development economics.《Human capital investment》SummarySchultz this "human capital investment" was called: a new field of research in human capital "Declaration of Independence", which makes nine claims in the article: "On tax policy should give preferential treatment to human capital; prevent people from human inactivity and aging capital; avoid investments in human capital man-made interference; perfect human capital market, banks should take the initiative to provide the necessary human capital costs, encourage private and public investment; government should bear most of the cost of investment in human capital , especially subsidized labor to cities; emphasis on low-income investment in human capital; clear education and health care also makes economic sense, they are an investment, the investment to reverse the imbalance in this regard; increased government investment, expand human capital investments to reduce income inequality;The basic meaning of human capital theory was proposed by Schultz: The capital is divided into physical and human capital in two forms. Human capital is reflected in the body of capital to labor quantity and quality of labor representation. Knowledge workers, technical level, high and low labor skills, human capital determines the different productive role in the economy, resulting in different degrees of national income growth.Schultz 's human capital theory has five main points :( A ) human capital exists in the human body , expressed as the sum of knowledge skills , physical ( health status ) values. A country's human capital can be measured by the number of workers, quality, and labor time .(B ) investment in human capital formation . There are five investment channels , including nutrition and health care costs , the cost of school education , in-service training of personnel costs, personnel costs that occurin the process of choosing and migration costs.(C ) investment in human capital is a major source of economic growth. Schultz said that growth in investment in human resources has undoubtedly improved significantly the quality of work put into the process of economic firefly improve on these quality has become an important source of economic growth. The ability of the people is the key to modern economic abundance .(D ) investment in human capital is the best investment returns . The purpose of investment in human resources is to gain . Schultz on the 1929 - 1957 U.S. economic growth in the relationship between investment in education made quantitative research , the following conclusions : the average income levels of investment in education was 17% ; revenue growth of investment in education accounted for the proportion of labor income growth 70% ; earnings growth in investment in education accounted for the proportion of national income growth of 33 %. In other words, investment in human capital investment is the highest rate of return on investment.(E ) The real part of the human capital investment spending is durability , and even more durable material than the durable consumer goods .2、外文文献译文《浅议人力资源战略中的福利管理》选文作者：李小敏福利管理的因素对福利进行决策和管理，有许多因素需要给予重视，如员工偏好问题，许多员工认为自己在公司福利中并没得到好处，甚至认为公司对自己的福利并不关心，这将导致福利的失败;而且许多公司没有把福利目标与公司战略相结合，没有严格控制成本，或者没有进行决策评价，造成福利投资效益的降低。
