薪酬最大的秘密在哪里
河北科技师范学院本科毕业论文(设计)外文翻译薪资:最大的秘密在哪里?院(系、部)名称:商务管理系专业名称:人力资源管理专业学生姓名:学生学号:指导教师:2012 年 03 月 14 日河北科技师范学院教务处制Compensation:What’s the Big SecretAbstractNo, you shouldn't be broadcasting your employees' salaries. But a new survey suggests that companies need to articulate how pay systems work and how individual compensation packages are determined. The payoff for you? More employees satisfied with their compensation.Keywords: compensation, communication, satisfaction,Over and over, we're told of the value in today's workplace of open communication, of transparency. Yet there's something critical that, in most organizations, remains top-secret. And that's compensation—specifically, what salaries are and how they are determined.It's in everybody's thoughts, yet rarely on their lips"It's perceived to be the unmentionable. We're the most open society in the world except for this one topic," says Peter LeBlanc, senior vice president of Sibson Consulting/The Segal Company (New York City). "Companies aren't bringing up the topic of pay, and people aren't seeking answers, because it's verboten."But a new study coauthored by LeBlanc shows that more and better communication about compensation can boost employees' satisfaction with their pay, leading to stronger commitment to the organization, enhanced trust in management, and other benefits. And it doesn't cost much to get these payoffs.The Knowledge of Pay study, sponsored by the human resources professional association WorldatWork, in Scottsdale, Arizona, surveyed more than 6,000 managers and employees from twenty-six organizations in theUnited States and Canada. The study does not suggest that companies reveal individuals' salaries. But it is telling people to talk about how pay systems work and how individual compensation packages are determined."We found at all income levels that the more knowledge our study participants have about their pay system, the more likely they are to be satisfied with their pay and engaged at work," LeBlanc says. "That's pretty powerful."Knowing more about compensation not only made more employees satisfied with their pay, it also fostered work engagement—for instance, it improved retention, employees' commitment to the company, and their willingness to refer friends and family to the organization. This could prove to be a bright note in today's economic climate: It is usually less expensive to improve and communicate a compensation structure than to increase actual pay.It's base pay that mattersThe study finds that base pay matters the most when it comes to communicating pay information. In a time of increasingly complex pay packages, this might disappoint the many companies that are committing time and dollars to bonus plans, short-term incentives, stock option programs, and the like. Nevertheless, the survey finds that satisfaction with base pay translates more strongly into work engagement than satisfaction with variable pay programs.Thus, organizations intent on doing a better job of communicating about compensation would do well to give the most attention to base pay.Why do organizations guard pay information so jealously, and why—as the Knowledge of Pay study finds—do employees so seldom ask for more information? Largely for the same reason people don't reveal their salaries to one another at cocktail parties. Several human resources and compensation experts interviewed believe the salary opaqueness that tends to prevail in workplaces is due to a long-standing cultural norm that has made pay a taboo subject. Other factors include the old notion that employee pay is the prerogative of top management; a worry that the more workers know about pay systems, the more they'll find to complain about; and management'sdesire to retain as much flexibility and subjectivity as possible in determining pay.Susan Zelinski-Davis, CCP, manager of employee performance and rewards at the insurance and financial services company Nationwide (Columbus, Ohio) believes companies with sound compensation programs have nothing to gain by hiding them. "Organizations should examine their pay systems and ensure they are well designed, which allows them to be open in communicating about them," she says. "As long as you have sound systems and guidelines, even if there remains some management discretion—and I don't think you can completely remove that—then you should be able to openly discuss pay."Perhaps surprisingly, managers surveyed for the Knowledge of Pay study report that employees ask about pay relatively infrequently. For example, just 17 percent of managers said they are frequently approached by employees with questions about their job grades, and only 15 percent are frequently asked about the consistency of pay practices. By contrast, 40 percent are asked frequently about performance issues.But the study authors are quick to discount a lack of interest as the reason for the relative dearth of questions about pay. More likely, they say, is the perception that such questions are unlikely to yield honest answers and, worse yet, could bring retribution.And in some cases, employees might be so confused about pay systems that they don't even know what to ask.The cost of silenceWith pay, as with any other subject, when there is an information vacuum, misinformation usually seeps in to fill it—and this misinformation is often more damaging than the truth. Martin Cormican, manager of compensation and benefits at Swarthmore College, notes that employees, even in highly secretive organizations, are bound to hear rumors about how management sets pay and how compensation compares with that in other (presumably more generous) organizations—even how much so-and-so in the office next door got in her last raise. "People take this information and internalize it, whether it's valid or not," he says. "That makes it more criticalthan ever for organizations to communicate their pay philosophy and strategy."Human resources professionals believe—and the new survey confirms—that employees are particularly keen on knowing they're being paid fairly relative to their peers inside the organization. Given the potential for the spread of misinformation and the damage to morale that can follow, tight-lipped leaders should ask themselves whether they are truly well served by maintaining silence on pay structures and how various jobs fit into them.Even if employees aren't asking managers for pay information, the study demonstrates that organizations are wise to give it. "You can have a great compensation program, but if you don't tell employees how it works, you're not getting the biggest bang for your buck," says Kay Sandvik-Schmitke, manager of surveys and research for WorldatWork.The new study finds that managers feel significantly less confident communicating compensation information than they do discussing and assessing performance. Whereas more than 80 percent of managers surveyed are either "very confident" or "completely confident" in their ability to give performance feedback and explain performance objectives, only about 40 percent report the same confidence in answering employee questions about job grades, how to move toward the maximum pay in a range, and consistency of pay practices in the company.The conversation can be particularly difficult when managers must explain a below-par raise to a report. To avoid such a conversation, Zelinski-Davis notes, managers are tempted to give proportionally equal raises to everyone. "Many managers tend to spread the dollars like peanut butter rather than allocating more dollars to higher-performing individuals and having to face the challenges of communicating proportionally smaller raises to average or below-average performers," she says. While this approach avoids a sensitive conversation, it robs management of one of its most powerful motivational tools, and it makes less than optimal use of the company's finite compensation dollars.Communicating about compensationOnce they make the commitment to openness about pay, companies cancommunicate effectively by following several key steps, according to the study authors and several human resources experts interviewed.Organizations typically rely on mass communications—manuals, handbooks, large staff meetings, etc.—to inform employees about pay. But the Knowledge of Pay study suggests that most people find such vehicles ineffective. More useful are personal and interactive approaches, often best performed by an employee's manager one-on-one.The study also suggests that companies can communicate pay information effectively through interactive, individualized e-learning courses conducted on intranets. That doesn't mean it's enough to send one-size-fits-all memos out via e-mail. "In our electronic environment, everything is easily pushed to everyone," says Bruce Lawson, partner and president of the human resources consulting firm Fox Lawson and Associates (Roseville, Minnesota). But with pay information, it really doesn't work. "When it comes to communicating pay information," he says, "people really like personal contact."Answering questions isn't enough, experts say. Managers should initiate the conversation, both in formal meetings and through informal contacts.Of course, for managers to serve well as the principal vehicles for communicating around compensation, they need to be better trained for the assignment than they are now. First, they themselves must learn how the pay system works. Then, managers need to learn to translate the information for their staffs—to use language appropriate to the lay audience and to apply the concepts to an individual's situation "on the ground."Make it relevantManagers can make pay communications most effective by focusing on aspects of the compensation plan relevant to the particular employee. For example, "a company can have different types of bonuses," Sandvik-Schmitke says. "If the bonus program pertains to the employee a manager is meeting with, the manager has got to put that person's line of sight on how the bonus program impacts them." Similarly, a lower-paid line worker ineligible for stock options certainly doesn't need details on that component of the pay plan. The pay conversation with this worker is best devoted to howhis raise was determined and tangible ways he can improve his performance to move up in the grade system.Employees obviously will not always like their raises, Lawson says. "But if people understand how you got there, there's a greater likelihood they'll accept the outcome. If I tell you your salary is being cut by 10 percent you're going to be upset. On the other hand, if we started out by educating the work force—maybe the company is having problems, and the alternative to salary cuts is layoffs—then at least you'll understand why the decision had to be made."Key to earning that acceptance is giving employees information about the company's fortunes, which requires treating them more like trusted insiders than an external audience to impress or mollify. It's easy to be open when the news is good. Less common, but just as necessary, is informing employees about problems and unresolved challenges and issues.At Fox Lawson, top management meets with the firm's employees every year to review financial performance and how that affects pay. "It makes employees feel that they really are a part of the business, that management trusts them," Lawson says. "It gives people that sense of belonging." The other benefit is that when people understand what's happening with the company as a whole, they're less likely to develop a persecution complex—the belief that they and their unit are being singled out for unfair treatment, Lawson says.No more mysteryHoneywell Electronic Materials, Sunnyvale, California, a participant in the Knowledge of Pay study, took quick action based on the study findings. Ina Marie Johnson, director of human resources at the 1,200-employee unit, organized a symposium in early August to review the results and how they applied to the company. Typical of organizations participating in the study, employees at HEM were generally satisfied with their actual pay but not with the poorly understood processes by which it was determined. After devoting the first day of the symposium to reviewing the research results and external best practices, HEM spent the second and third days educating managers about the company's compensation system, with the aim of preparing them tocommunicate more effectively with their reports. "The whole idea," Johnson says, "was to take the mystery out of our pay processes."As a second step, HEM launched in late August a customized, online "Total Rewards Tool." Honeywell employees can now punch in a password to access a Web page that documents their complete compensation package —base pay, bonuses, benefits, etc.—and its cash value.The thought of communicating more openly about pay might cause squirming in the executive quarters of organizations that are used to keeping compensation information close to the chest. But in LeBlanc's view, open and direct communication about compensation is vital to strong employer-employee relations. Employees increasingly expect and desire to be treated less like hired hands and more like integral members of the team; the very act of letting them in on the long-held compensation "secret" can create good will, LeBlanc says. Coupled with that is an economic climate in which management is less able to buy employee happiness through raises."I can't think of a better time in the last twenty years to reveal more about how pay systems work and compensation decisions are made," LeBlanc says. "There's a lot of retrenchment in pay right now. Maybe you can't distribute more pay right now, but you certainly can distribute more knowledge."原文出处:Tom Krattenmaker.

新版河北科技大学设计学专业考研经验考研参考书考研真题
考研已落下帷幕考研虽然已经结束好长时间,而它对于我来说,就像是昨天刚发生一样,清晰且深刻。
回首考研的这段经历,我收获了很多,也成长了许多。
开始基础复习的时候,是在网上找了一下教程视频,然后跟着教材进行学习,先是对基础知识进行了了解,在5月-7月的时候在基础上加深了理解,对于第二轮的复习,自己还根据课本讲义画了知识构架图,是自己更能一目了然的掌握知识点。
8月以后一直到临近考试的状态,开始认真的刷真题,并且对那些自己不熟悉的知识点反复的加深印象,这也是一个自我提升的过程。
考研一路走来,真的很辛苦,考研帮里学长学姐们分享的宝贵经验不仅能让我打起精神背水一战,还使我的复习有条不紊地进行。
初试成绩出来的这两天,酝酿了一下,我也想为将要参加下一届考研的的学弟学妹们写一篇文章,希望你们从复习的开始就运筹帷幄,明年的这个时候旗开得胜。
文章字数很多,大家有时间可以阅读,文末有真题和资料下载分享,谢谢大家。

河北科技师范学院本科毕业设计外文翻译多层住宅建筑给排水设计的几个问题院(系、部)名称:专业名称:学生姓名:学生学号:指导教师:年月日河北科技师范学院教务处制The multilevel residential housing is given and drains off water severalquestions designedSummary :This text give and drain off water on multilevel residential housing design supply water the exertion of the tubular product , Way of laying of pipeline, water gauge produce family set up, establishment and air conditioner condensation water of pot-type boiler discharge issue goes on the discussion , And put forward some concrete views.Keyword:Skyscraper, supply water the tubular product , the pipeline is laid, The water gauge, the solar water heaterThe skyscraper is simple with its auxiliary facility, the fabrication cost is low, the characteristic such as being convenient of estate management, Receive the welcomes of the real estate developer and vast resident of small and medium-sized cities very much. How project planning and design of inhabited region, scientific and technological industry of comfortable house, lead the request according to 2000, Improve the design level of the house, build out a comfortable living space for each household, It is each designers duty. As the heart of the house --The kitchen, bathroom, is that the function is complicated, hygiene, safe and comfortable degree are expected much, It is miscellaneous to build, the space expecting much in technology. So, the designer must consider synthetically with the idea and method of global design that the kitchen, bathroom give installation of the drainage pipeline and equipment,etc. . Give and drain off water on skyscraper design supply water exertion, to lay pipeline of tubular product, water gauge produce family set up, establishment and empty of pot-type boiler now Transfer condensation water discharge issue discuss together with colleagues.(1)supply water tubular product select problem for use Traditional watersupply tubular product adopt zinc-plated steel tube generally, because zinc-plated steel tube exchange the corrosion, Use short-lived , use for and send domestic water can satisfied with water quality sanitary standard shortcoming, Ministry of Construction is popularizing the application of the feed pipe of plastics energetically . A lot of districts and cities have already expressed regulations: Forbid designing and using the zinc-plated steel tube , use widely the feed pipe of plastics. The plastics supply water In charge of compared with metal pipeline, light, it is fine to able to bear the intensity of keeping, Send obstruction little liquid , able to bear chemistry better to corrode performance, it is convenient to install, The steel energy-conservation of the province, merit of having long performance life etc.. Supply water and use plastics pipeline: Hard polyvinyl chloride( PVC-U), high density polyethylene( HDPE), pay and unitepolyethylene( PEX) , modify the polypropylene( PP-R, PP-C), gather butene( PB), aluminium mould and compound and in charge of and the steel is moulded and compound and is managed etc.. Choice of tubular product economic comparative course of technology, technology should from pressure, temperature, environment for use, install method,etc. go on and consider, Combine owners at the same time request and the house of grade,carry on and fix after being consider synthetically technology not economic. The above plastics supply water tubular product can supply water tubular product as house life. The economic and functional house conciliating Strand room in the face of the masses of with low- and medium-level incomes resident, can select for use hygiene grades of hard polyvinyl chloride in charge of as feed pipe mainly, In order to reduce the fabrication cost; Medium-to-high grade commodity apartment available aluminium Mould and compound and in charge of or other plastics supply water the tubular product as the feed pipe. House mix hot water temperature that water order exceed 600 C, so above-mentioned tubular product in charge of except hard polyvinyl chloride and aluminium plastics compound and in charge of( PE-AL-PE), Mostly the tubular product can be regarded as the hot water pipeline of the house.( 2) pipeline lay problem 1. give and drain off water it set up there arent one that in charge of1)Will install it in the corner place of the kitchen, bathroom tomorrow. Adopting this kind of way of laying more in the design of house in the past, it is convenient for it to construct, But will reveal the pipeline and hinder the room beautifully tomorrow Watch, the households will mostly be hidden with the light quality material in the equipment two times.2)Will install it in the overcast angle place of the outer wall of the building tomorrow. Way this suitable for southern weather warm district only, the minimum temperature in winter cant be lower than zero degrees Centigrade, In case water pipe water-logging freeze ice is bloated to split pipeline, influence household use. Pipeline lay in outer wall, influence building to be beautiful, too inconvenient on manage and maintain in the future.3)Lay it in the pipeline well. This way makes the room clean and beautiful , but the pipeline well has taken up the area of the bathroom, And pipeline construct, maintain relatively more difficult. Bathroom set up concentrate pipeline well, concentrate pipeline on assign in the well feed pipe, drain pipe, This is that the civilized importance lives in the kitchen of comfortable house, bathroom Embodiment. I think : Should consider the establishment of the pipeline well of the bathroom in the medium-to-high grade building conceptual design of commodity apartment, Improve quality of using of bathroom promptly so , can solve hardpolyvinyl chloride drain pipe rivers noise heavy problem, Improve the environmental quality level of the room; Whether for bathroom in the areas for little economic and functional house and Overcome difficulties room, warm area give and drain off water and set up and in charge of and can consider and lay in the outer wall in the South, In order to increase using the space of the bathroom; Pipeline install and in the room, should influence kitchen, bathroom every sanitary equipment use of function tomorrow2. supply water and prop up there arent tube House supply water prop up and in charge of pipe diameter one ≤ 32mm, de of battle,, little plastics feed pipe of pipe diameter is the crooked state, So the house supplies water and is propped up and in charge of being recommended and adopted and set up secretly. Supply water to prop up to manage darkly There are thes way had:1)Set up in the brick wall secretly. Wall turn on and in charge of trough in brick when constructing, in charge of trough width tube +20 mm, de of external diameter,, degree of depth tube external diameter de, The pipeline is imbedded and managed directly Trough, and with in charge of card fix in trough of inning charge of son.2)Whether pipe diameter supply water and prop up and last de ≤ 20mm,can set up at floor secretly piece make level by layer. Turn on and in charge of trough in floor( ground) the board when constructing, it wides trough have to be de +10 mm deeply 1/2 of the de, Half pipeline imbed and in charge of trough, and with in charge of card fix in trough of inning charge of tube. Aluminium mould compound and in charge of and pay and unite polypropylene in charge of pipeline adopt metal pipe fittings connection, Must strengthen and in charge of trough size when adopting and set up secretly, and rivers some flood peak loss relatively heavy. Assign the relative house that concentrated to the kitchen, bathroom interior hygiene utensil, Can adopt and divide Water device go on and join , divide water device whether one more than branch in charge of and connect, every hygiene utensil supply water and prop up and in charge of and connects and publishes from the water dividing device separately. Can already prevent the tube burying the pipeline secretly from being connected like this Permeate the question. Can reduce some flood peak lost, decrease the fabrication cost of pipe networks3)Drain off water and prop up the tube to lay House room drain off water and in charge of and should set up at the time of inning this each, drain off water and in charge of permeating sideways like this canning prevent the sewage from waiting for the pollutant to enter the neighbor family sideways, Will not influence the neighbor either when the pipeline is maintained Normal life of one. Kitchen wash water drainage of basin propped up and in charge of generallying inserts draining off water to stand to manage this layer of floor sideways; Floordrain drain off water propped up and in charge of laying the room of lower floor. A lot of colleagues think now: Whether kitchen the ground it lay ceramic tile of,whose name is clean in when need develop with water,not strong in meaning to set up floor drain, So kitchen set up ground floor drain, avoid and drain off water and prop up and in charge of and enter neighbor family sideways already so, Can increase using the space of the kitchen . Bathroom drain off water and prop up and in charge of and lay concrete measure have in this layer sideways inside:1)Improve the bathroom ground . Ground tendency high 150mm, adopt back row type take stool pot, washing basin, bath tub, water drainage of floor drain in charge of and bury in cushion layer secretly sideways.2)Adopt the sinking type bathroom. Bathroom sink 350mm the floor, hygiene utensil drain off water and in charge of and bury on sinking space secretly sidewaysTwo method these can realize water drainage of bathroom prop up and in charge of earths surface to bury underground this one without entering the neighbor family sideways. Bury pipeline when installing, construction quality must check on strictly, can construct bathroom ground after confirming qualified secretly, So as not to leave the hidden danger in giving in the future using. Bathroom ground construct and can pack coal ash light quality material , also can adopt and lay bricks impracticable to lay plate making construct ground, Ground must make waterproof to deal with, method can waterproof to deal with according to roofing, make two oil one rubber and plastic ointment waterproof cloth.3) water gauge the open air set up problem The water gauge is had indoors, not only the work load of checking meter is very heavy , but also make the security and privacy of the house reduce greatly . So house divide into households of water gauge or divide households of figure of water gauge Show that should be set up in the open air. Skyscraper water gauge the open air set up following several kinds of forms: Whether 1.adopt far it pass by water gauge Change the ordinary water gauge into and pass the water gauge far, is joined the water gauge and data gathering machine by a signal line, And then reach intelligence to manage( the computer). Its merit lies in saving a large amount of people Strength comes to check meter, the data are accurate, the shortcoming is that the fabrication cost is high. Whether 2.adopt magnetic stripe card of by water gauge Users buy the electronic card of the running water Company in advance , then insert it in the storing device of the water gauge, Card amount of money deduct automatically on the water, this way user need to prepay the water rate, The price of the water gauge is relatively high.3. adopt it set up at the open air water gauge not ordinary1)The water gauge is set up in the stair have a rest in the alcove of the platform. Household watersupply to prop up and manage and enter the kitchen, bathroom after the water gauge is measured.

This sensor requires very small silicon area and low power consumption, and the simulation results show that its accuracy is in the o rder of 018℃. The proposed sensor can be easily implemented using regular CMOS process techno logies, and can be easily integrated to any VLS I circuits to increase their reliability.Key words: temperature sensor; thermal testability; frequency output. EEACC: 1265A; 2560; 2570DCLC number: TN 47Document code: A Article ID: 025324177 (2004) 03202522051IntroductionDue to the advances in the fabricaion process field of in tegrated circu its, the component den sityand the overall power dissipat ion of the high per fo rmance VLSI chips increase cont inuously. At the beginning of this century, the power dissipated in asingle ch ip has exceeded 100W , and tightly packed chip assemblies as the multichip modules can even dissipate thou sandswatts. Therefore, the thermalstate of integrated circu its has been always a great prob lem concerned and is considered as a bottle neck in increasing the in tegrat ion of elect ron ic system s.To overcome this problem , many researchers developed low 2power design techn iques for VLS Isystems. In order to avoid thermal damages,continuous thermal monitoring should be appliedduring both the production reliability testing and the field operation. An eff icient way is to buildtemperatu resensors in to all VLSI chips, with theapp ropriate circuitry p roviding easy readout. Insome earlier works , the researchers usedtheparasitic, lateral or sub strate bipolartran sistors,which can be realized in mo st of the CMOS processes, as thermal sen so rs. These are u sually PTAT sensors. The weakness of these senors is that the bipolar structu resare not well characterized in a MOS process. Thus, although they canp rovide a sat isf iect solution for a given process, thecircu its can not be regarded as a general CMOS approach and can not be widely used.2Problem formulationThere are various temperature sensors suitable for the rmalstate verification of in tegrated circuit microstructures such as the rmoresistors, pnjunctions, and the exploitation of the weakinversion of MOS transistors. Our objective is to convert the temperature to an oscillat ing signal to make it compat ib le to digital circu it design method and facilitate the evaluat ion of the temperature sensed. A temperatu re sen so r based on a ringo scillator is introduced in Ref., this cell guarantees a accuracy of 3℃that is marginally accep table as a chiptem perature sensor but the silicon area required is rather big. AMOS temperature controlled oscilla to risused as asensor to monitor the thermal state of microelectronic structu res in Ref. How ever, this sensor requires about 10 to 15mW power to drive the thermal delay line and the dissipatertran sistor.To overcome these inconven iences, w e th inkthat the temperature sensors to be used as builtinun its for VLSI circuits online the rmalmoni to ring should meet some special requirements as follows:( 1 ) Nearly linearity in a temperatu rerange(usually 0~ 100℃) ;( 2 ) Low power consumption (no more than 1 mW ) ;( 3 ) Simple structure and small silicon area(usually no more than 40 transistors) ; ( 4 ) Easy read out results with favorably digital output signal (e. g. , the frequency of asquare wave which carries the temperature information) ;( 5 ) Easy (one point) calib rat ion;( 6 ) High accu racy ( in the order of 2℃ or less) ;( 7 ) Compat ib ility w ith the p resen t CMO Sp rocess;Con sidering the given requirements, we present a new builtin temperatu resensor meeting all the above requirements3 Built- in thermal mon itor ing sensorOur new temperature sensoris a voltage controlled relaxation o scillato rbasedtemperature sensor shown in Fig. 1. The circuit consists of two parts, a voltageout put sensor and a relaxation oscillator.F ig. 1 Temperature sensor designed based on avoltage2cont ro lled relaxation oscillator3.1Voltage-output sen sorOur voltage output sensor circuit exploits the temperature dependence of the mosimportant parameter of the MOS transistor, namely, the thresh old voltage (V T ). The thresh old voltage has a negative temperature coeff icient as:V T (T ) = V T (T 0) + a (T - T 0) (1)where a is the temperature coeff icient with atypical value of - 118mVöK in CMOS 0135Lm 5V technology; V T (T 0 ) is the value of the th reshold voltage at temperatu re T0.As shown in Fig. 1, the voltage output sensor is a th reshold voltage reference cell. The pchannelt ransistors P1, P2 constitu teacurrent mirror. The current of transist or N1 is mirrored to tansistors N 2,N 3, and N 4. The vo ltage drop on these t ran sistors isfed back to the gate of N 1. Fo r easy calculat ing,we choose asame size of the transistors N 2,N 3, and N 4 (BN 2= BN 3= BN 4) , and we choose approp riatesize of the other transistors to ensure that the transisto rs P1, P2, N 1, N 2, N 3, and N4 are all in the state of saturation. Then the out put voltages of th is sen so r are in direct proportion to the thresh old voltage and linear with temperature and theirvalues are:V H = V T (1 +2K P12K P12 - 3K N 12) = k1V T (2)V L = V T (1 +2K N 12K P12 - 3K N 12) = k2V T (3)where is determined by the ratio between the gatesizes of the nchannel t ransistor N 1 and N 2, and is the ratio of the gate sizes of the pchannel transistor P1 and P2.By adju st ing the sizes of the t ran sisto rs, w efound shou ld be b igger than threetimes of,when the transistors P1, P2, N 1, N 2, N 3, and N 4 are all in the state of saturat ion.The advantages of th is circuit arrangeme t arethe simplicity and the stable outpu t. A n important feature is that the output voltages of V H and V L arepractically independen t of the supply voltage (V DD ).3. 2Voltage-con trolled relaxa t ion osc illa torThe quick in terfacing of the analogue, current output sensor with the digital environmen t is not asimple task. To overcome this problem we usea voltage controlled relaxat ion oscillato r as the voltage frequency converter. The output signal of th isconverter is asquare w ave, the frequency of which carries the temperatu re info rmation. This frequency can be easily turned in to adigital number bycoun ting the square wave pulses in a prescribedt ime window.As shown in F ig. 1, the curren t of the resisto rism irro red using thet ran sisto rs P3, P4, P5,N5,N6 to provide the same sou rce and sink current s to charge and discharge thecapacitor C. Assum ing thein it ial value of the f o sc is logic 0, then the t ran sistor P6 is on and the t ran sisto rN 7 is off cau sing the capacitor C to be charged using the source curren t I un t il V cexceeds the upper th resho ld V H. W hen th isoccu rs, the output latchtoggles and the logic valueof f o sc becomes logic 1, w hich in turn makes thet ran sistor P6 off and the tran sistor N 7 on. Th ismakes the capacitor C to be discharged by the sinkcurren t until the capacit r voltage falls below alowerthreshold V L at w h ich t ime the en t ire cyclerepeats. N eglecting the delay of the comparators,latch and transistors P6 and N 7, the oscillation cycle time should be:As the current is small and the W öL rat io of the transistor P3 is chosen to be big in this design,the V gsp can be appro ximated to the th reshold voltage of the transistor P1 and therefo e the currentcan be approximated byAnd the temperature dependence of the resistor R s iswhere k is the temperatu re coeficien t of the resistor,with typical value k= 255×10- 6ö℃fo r polysilicon sheet resistor in the CMOS 0135Lm 5V technology.Therefore, the oscillation cycle time is foundto beThis equation implies that the cycle t ime ofthe relaxation oscillator is nearly linear with temperature, and then the f requency of the o scillator is4Simulation results and discuss ionThe simulation result of the voltage output the rmalsen sorisillustrated in F ig. 2, and the varia ion of the relaxat ion oscillator based sensor oscillation cycle t ime and f requency versus the ch iptemperatu re is shown in Fig. 3.To evaluate a buildin thermal sensor, thereare three important characterist ics: accu racy, sili2con area ( transistor number ) , and powerdissipation. The characterist ics of our voltage cont rolled relaxation oscillator based sensor is shown in Table 1:5ConclusionIn this paper, apractical and efficient built intemperatu resensor for the rmalmonito ring of the integrated circuits is in troduced. The main advantages of the presented chip temperature sensors are low silicon area, low power dissipation, digital output inform of oscillation frequency, high accuracy,and easily implemented using regular CMOS process techno logies.

There are at least a dozen different editions of Microsoft SQL Server aimed at different audiences and for different workloads (ranging from small applications that store and retrieve data on the same computer, to millions of users and computers that access huge amounts of data from the Internet at the same time).True to its name, Microsoft SQL Server's primary query languages are T-SQL and ANSI SQL.HistorySQL Server 2005 (codename Yukon), released in October 2005, is the successor to SQL Server 2000. It included native support for managing XML data, in addition to relational data. For this purpose, it defined an xml data type that could be used either as a data type in database columns or as literals in queries. XML columns can be associated with XSD schemas; XML data being stored is verified against the schema. XML is converted to an internal binary data type before being stored in the database. Specialized indexing methods were made available for XML data. XML data is queried using XQuery; Common Language Runtime (CLR) integration was a main feature with this edition, enabling one to write SQL code as Managed Code by the CLR. SQL Server 2005 added some extensions to the T-SQL language to allow embedding XQuery queries in T-SQL. In addition, it also defines a new extension to XQuery, called XML DML, that allows query-based modifications to XML data. SQL Server 2005 also allows a database server to be exposed over web services using Tabular Data Stream (TDS) packets encapsulated within SOAP (protocol) requests. When the data is accessed over web services, results are returned as XML.For relational data, T-SQL has been augmented with error handling features (try/catch) and support for recursive queries with CTEs (Common Table Expressions). SQL Server 2005 has also been enhanced with new indexing algorithms, syntax and better error recovery systems. Data pages are checksummed for better error resiliency, and optimistic concurrency support has been added for better performance. Permissions and access control have been made more granular and the query processor handles concurrent execution of que ries in a more efficient way. Partitions on tables and indexes are supported natively, so scaling out a database onto a cluster is easier. SQL CLR was introduced with SQL Server 2005 to let it integrate with the .NET Framework.SQL Server 2005 introduced "MARS" (Multiple Active Results Sets), a method of allowing usage of database connections for multiple purposes.SQL Server 2005 introduced DMVs (Dynamic Management Views), which are specialized views and functions that return server state information that can be used to monitor the health of a server instance, diagnose problems, and tune performance.SQL Server 2005 introduced Database Mirroring, but it was not fully supported until the first Service Pack release (SP1). In the initial release (RTM) of SQL Server 2005, database mirroring was available, but unsupported. In order to implement database mirroring in the RTM version, you had to apply trace flag 1400 at startup. Database mirroring is a high availability option that provides redundancy and failover capabilities at the database level. Failover can be performed manually or can be configured for automatic failover. Automatic failover requires a witness partner and an operating mode of synchronous (also known as high-safety or full safety).EditionsMicrosoft makes SQL Server available in multiple editions, with different feature sets and targeting different users. These editions are:Mainstream editionsDatacenterSQL Server 2008 R2 Datacenter is the full-featured edition of SQL Server and is designed for datacenters that need the high levels of application support and scalability. It supports 256 logical processors and virtually unlimited memory. Comes with StreamInsight Premium edition.EnterpriseSQL Server Enterprise Edition includes both the core database engine and add-on services, with a range of tools for creating and managing a SQL Server cluster. It can manage databases as large as 524 petabytes and address 2 terabytes of memory and supports 8 physical processors.StandardSQL Server Standard edition includes the core database engine, along with the stand-alone services. It differs from Enterprise edition in that it supports fewer active instances (number of nodes in a cluster) and does not include some high-availability functionssuch as hot-add memory (allowing memory to be added while the server is still running), and parallel indexes.WebSQL Server Web Edition is a low-TCO option for Web hosting.WorkgroupSQL Server Workgroup Edition includes the core database functionality but does not include the additional services.ExpressSQL Server Express Edition is a scaled down, free edition of SQL Server, which includes the core database engine. While there are no limitations on the number of databases or users supported, it is limited to using one processor, 1 GB memory and 4 GB database files (10 GB database files from SQL Server Express 2008 R2). The entire database is stored in a single .mdf file, and thus making it suitable for XCOPY deployment. It is intended as a replacement for MSDE. Two additional editions provide a superset of features not in the original Express Edition. The first is SQL Server Express with Tools, which includes SQL Server Management Studio Basic. SQL Server Express with Advanced Services adds full-text search capability and reporting services.Specialized editionsAzureMicrosoft SQL Azure Database is the cloud-based version of Microsoft SQL Server, presented as software as a service on Azure Services Platform.Compact (SQL CE)The compact edition is an embedded database engine. Unlike the other editions of SQL Server, the SQL CE engine is based on SQL Mobile (initially designed for use with hand-held devices) and does not share the same binaries. Due to its small size (1 MB DLL footprint), it has a markedly reduced feature set compared to the other editions. For example, it supports a subset of the standard data types, does not support stored procedures or Views or multiple-statement batches (among other limitations). It is limited to 4 GB maximum database size and cannot be run as a Windows service, Compact Edition must be hosted by the application using it. The 3.5 version includes supports Synchronization Services.SQL CE does not support ODBC connectivity, unlike SQL Server proper.DeveloperSQL Server Developer Edition includes the same features as SQL Server Datacenter Edition, but is limited by the license to be only used as a development and test system, and not as production server. This edition is available to download by students free of charge as a part of Microsoft's DreamSpark program.Embedded (SSEE)SQL Server 2005 Embedded Edition is a specially configured named instance of the SQL Server Express database engine which can be accessed only by certain Windows Services.EvaluationSQL Server Evaluation Edition, also known as the Trial Edition, has all the features of the Enterprise Edition, but is limited to 180 days, after which the tools will continue to run, but the server services will stop.Fast TrackSQL Server Fast Track is specifically for enterprise-scale data warehousing storage and business intelligence processing, and runs on reference-architecture hardware that is optimized for Fast Track.Parallel Data Warehouse (PDW)A massively parallel processing (MPP) SQL Server appliance optimized for large-scale data warehousing such as hundreds of terabytes.ArchitectureProtocol layerProtocol layer implements the external interface to SQL Server. All operations that can be invoked on SQL Server are communicated to it via a Microsoft-defined format, called Tabular Data Stream (TDS). TDS is an application layer protocol, used to transfer data between a database server and a client. Initially designed and developed by Sybase Inc. for their Sybase SQL Server relational database engine in 1984, and later by Microsoft in Microsoft SQL Server, TDS packets can be encased in other physical transport dependent protocols, including TCP/IP, Named pipes, and Shared memory. Consequently, access to SQL Server is available over these protocols. In addition, the SQL Server API is also exposed overweb services.TOOLSVisual StudioMicrosoft Visual Studio includes native support for data programming with Microsoft SQL Server. It can be used to write and debug code to be executed by SQL CLR. It also includes a data designer that can be used to graphically create, view or edit database schemas. Queries can be created either visually or using code. SSMS 2008 onwards, provides intellisense for SQL queries as well.SQL Server Management StudioSQL Server Management Studio is a GUI tool included with SQL Server 2005 and later for configuring, managing, and administering all components within Microsoft SQL Server. The tool includes both script editors and graphical tools that work with objects a nd features of the server. SQL Server Management Studio replaces Enterprise Manager as the primary management interface for Microsoft SQL Server since SQL Server 2005. A version of SQL Server Management Studio is also available for SQL Server Express Edition, for which it is known as SQL Server Management Studio Express (SSMSE).A central feature of SQL Server Management Studio is the Object Explorer, which allows the user to browse, select, and act upon any of the objects within the server. It can be used to visually observe and analyze query plans and optimize the database performance, among others. SQL Server Management Studio can also be used to create a new database, alter any existing database schema by adding or modifying tables and indexes, or analyze performance. It includes the query windows which provide a GUI based interface to write and execute queries.Microsoft SQL ServerMicrosoft SQL Server是一个关系数据库服务器,由微软开发的,它是一个软件产品,其主要功能是存储和检索数据,其他应用软件的要求,无论是那些在同一台计算机或另一台计算机上运行,通过网络(包括互联网)。

广东技术师范学院天河学院本科毕业设计外文翻译译文学生姓名宋岸其院(系)广东技术师范学院天河学院专业班级机械设计制造及其自动化指导教师李兆瑞完成日期2015年4月The robot control system in PLCIs the national machinery industry equipment department, is to provide consumer durable goods for people's life for the national economy to provide equipment and industry. Machinery industry scale and technology level is an important symbol to measure the strength of the national economy and the level of science and technology. Therefore, all countries in the world to develop machinery industry as a strategic focus of the development of the national economy (Zhang Zhixian, 2002). The new century, with the development and progress of science and technology and the level of production led to the rapid development of the machinery industry. In modern industry, the production process of mechanization, automation has become a prominent theme. However, in the machinery industry, processing, assembly and other production is not continuous. These will not rely solely on human continuous production processes together, not only time-consuming and inefficient. At the same time, the labor intensity is very large, sometimes mistakes and hurt. Obviously, which seriously restrict the impact of efficiency and the automation of the entire production process. The application of manipulator is a very good solution to this situation, it does not exist by repeated mistakes, can effectively avoid accidents (Yang Yongqing, 2008).In the machinery industry, has the following significance of the application of manipulator.Application of mechanical hand, is conducive to the improvement of material transfer, workpiece handling, tool replacement and machine assemblyautomation, which can improve labor productivity, reduce production costs, accelerate the realization of industrial production mechanization and automation pace.In high temperature, low temperature, high pressure, low pressure, dust, noise, odor, radioactive or other toxic pollution and narrow working space in other occasions, with manual operation is dangerous or impossible. Application of mechanical hand can replace some or all people to complete the work safely, greatly improve the working conditions. At the same time, in some simple action but repeated operation, the manipulator instead of manual work, can avoid fatigue caused by operation or neglect of personal accident.Application of mechanical hand instead of manual work, this is a direct side reduction in manpower at the same time, due to the application of mechanical hand can work continuously, which is reduced to another side of human. Therefore, the automatic machine and automatic processing production line currently has almost mechanical hand, to reduce the manpower and accurately control the production rhythm, easy rhythm of production.With the development of modern industrial technology, industrial automation technology is more and more high, working environment and working content also requires a simple ideal, for some reciprocating work by robot remote control or automatic completion is very important. This can avoid some of the people can not contact the substances cause harm to human body, such as metallurgy, chemical, pharmaceutical, aerospace etc.. For the domestic and foreign research level of the manipulator is not the same, but represent the most advanced technology in Japan, his humanity is as the acme of perfection, automation, these techniques rely on control theory, new material science, it is the integration of a variety of cutting-edge technology of modern machines. Our country has been in the industry for some applications, automatic control, has been widely used in flexible manufacturing system, but the level of automation of our country needs to be improved, only equivalent to the world advanced level of technology in the eighty's. With the development of industrial modernization, manipulator technology increases, the trend of the development of high strength, strong flexibility, accurate and reliable, can automatically detect and motor command, with advanced artificial intelligence, that only the usual simple maintenance, this is also the development trend of the foundry.At present, the world of high-end industrial manipulator has high accuracy, high speed, multi axis, the development trend of lightweight. The positioning accuracy can meet the requirements of micron and submicron particles, the speed can reach 3M/S, mass production reached 6 total weight of products 2Kg axis, system load has exceeded 100Kg. More important is the manipulator, flexible manufacturing system and flexible manufacturing unit combination, so as to fundamentally change the current manufacturing system manual operation state. At the same time, along with the miniaturization and micromation of the manipulator, its application will break through the traditional mechanical field, and toward electronic information, biotechnology, life sciences and aerospace and other high-end industry development.This design is the use of programmable controller PLC as a carrier of a manipulator driving device, used to achieve the function of writing, and can change the control parameters according to the requirements of the change of demand.Through there to provide for the school library database and network information collection, I have a lot of inquiries to the literature on this topic. They include books, journals, academic papers etc.. The documents involved in all the relevant aspects of the design can be better to complete the design as a reference.The comprehensive literature content can see that PLC has the following advantages, it can adapt to the harsh environment of the industrial field, high reliability. General requirements in industrial production control equipment has a strong anti-interference ability. PLC and one's own knack in in this area are: it adopts photoelectric isolation device in hardware in order to prevent the interference of output feedback input; the shielding measures to prevent electromagnetic interference space; set the filter, to eliminate the interference between external interference andinfluence of each module; the interlock and interlock control, self diagnostic circuit and module type structure and other measures, in order to improve the reliability and interchangeability of hardware module; the software adopts fault self detection, self diagnosis and other measures.The advantages of other practical aspects of the 1.PLC software is easy to learn.2 PLC 3.PLC easy to use; small volume, light weight, easy to install. Because the PLC has a series of advantages, widely used in industrial control, the following three kinds: (1) control switch, sequential logic control. That is to replace the relay control system, such as the metallurgical industry in the feeding system, rolling mill, continuous casting machine, for shear control system; automatic production line, automatic processing machine, all kinds of machinery industry manipulator, Longmen milling machine control; light industry in the injection molding machine, packaging machine, food processing machinery etc.. (2) analog control. Such as temperature, pressure, flow and so on; (3) acquisition, processing and analysis of data. Such as data acquisition, arithmetic, function, logic operation, data transmission, conversion, holding order and operation control in the look-up table.The PLC control as the control of mechanical hand design system is a convenient, practical, reliable control system design. Very understand the design through the collection of data and the initial plan I have to believe that, under the guidance of the teachers and my own efforts I can be very good to complete the design task, although the period will certainly encounter difficulties in this or that, but I have the confidence to do it all.外文中文翻译:基于PLC的机械手控制系统机械工业是国民的装备部,是为国民经济提供装备和为人民生活提供耐用消费品的产业。

附件1:外文资料翻译译文基于PLC的洗瓶机可循环控制系统的开发摘要在这篇文章中,我们将把循环控制系统融入到洗瓶机中,这是我们整体设计的一个思路。
因为在某些地方,控制好液体流动是非常有用的,比如说在化学和石油工业中,通过对水的控制可以对瓶子进行清洗。
在这里,有三个参数需要控制1、液位2、流量3、压力。
在这些参数之间,存在相互作用关系,想要更好的洗瓶,就得控制压力和流量的大小。
对于这些变量,我们可以使用PLC来控制,使用PLC 可以增加效率和提高响应时间。
我们需要在洗瓶机的输出端装一个阀门,通过这个阀门来对循环系统进行调控。
如今,输入和输出的安全性是行业必须重视的。
所以,安全性也是我们需要考虑的。
对于不同的传感器和阀门,我们都用PLC来直接控制。
因为控制它们的程序不同,PLC就会产生不同的信号。
这种控制方式,同时可以控制液位、流量和压力的大小。
最后,需要连接一个额外的人机界面(HMI),用户可以通过这个控制器来更改设定值。
关键词循环控制压力控制洗瓶机流量控制液位控制循环安全1 引言过程循环系统通常使用在石油、天然气、化工、饮料等工业中。
它保证了气体或液体参数的准确性。
过程循环系统是一种确保制造商在保持工作状态下,在规定范围内,保证最大利润的同时也保证质量和安全。
我们已经设计出一个循环控制系统,这套系统专为洗瓶机而开发的。
洗瓶机大约每小时能够清洗30000到170000瓶。
在这台机器上,我们需要对水、温度和化学成分进行控制,其中对水的控制是最重要的。
因为机器每天将使用数千升的水,我们可以适当的调整,可以循环利用这些水。
如果这些参数不能达到相互平衡,这将直接影响产品的成本。

河北科技大学机械设计制造说明书
1引言1.1 轧机的发展轧机是实现金属轧制过程的设备。
泛指完成轧材生产全过程的装备﹐包括有主要设备﹑辅助设备、起重运输设备和附属设备等。
但一般所说的轧机往往仅指主要设备。
据说在 14世纪欧洲就有轧机,但有记载的是 1480 年意大利人达·芬奇 (Leonardo da Vinci) 设计出轧机的草图。
1553 年法国人布律列尔 (Brulier) 轧制出金和银板材,用以制造钱币。
此后在西班牙﹑比利时和英国相继出现轧机。
英国于 1766 年有了串行式小型轧机,19世纪中中期,第一台可逆式板材轧机在英国投产,并轧出了船用铁板。
1848 年德国发明了万能式轧机,1853 年美国开始用三辊式的型材轧机,并用蒸汽机传动的升降台实现机械化。
接着美国出现了劳特式轧机。
1859 年建造了第一台连轧机。
万能式型材轧机是在 1872 年出现的;20世纪,随着冶金工业的发展,已出现多种类型的轧机,其中有用两架三辊粗轧机和五架四辊稿轧机组成的半连续式带钢轧机。
现代轧机发展的趋向是连续化、自动化、专业、,产品质量高、消耗低。
60年代以来轧机在设计,研究和制造方面取得了很大的进展,使带材冷热轧机、厚板轧机、高速线材轧机、H型材轧机和连轧管机组等性能更加完善,并出现了轧制速度高达每秒钟 115米的线材轧机、全连续式带材冷轧机、5500毫米宽厚板轧机和连续式 H型钢轧机等一系列先进设备。
轧机用的原料单重增大,液压 AGC、板形控制、电子计算机程序控制及测试手段越来越完善,轧制品种不断扩大。
一些适用于连续铸轧、控制轧制等新轧制方法,以及适应新的产品质量要求和提高经济效益的各种特殊结构的轧机都在发展中。
1.2 轧机的主要设备由轧辊、轧辊轴承、轧机机架、轧机轨座、轧辊调整装置、上轧辊平衡装置、传动装置、附属设备等组成。
1.3 多辊轧机的用途(1)轧制高强度的金属和合金薄带材。
用四辊轧机冷轧高强度薄带材,不但不经济,而且在许多情况下的技术上还不可能达到。

城市停车问题及交通运行效率管理规划方案研究伴随着城市化和机械化的迅猛发展,发展中国家进展呈现出的的流动性愈发清晰。
继交通需求急剧增大,在许多大城市,停车问题就显得更为重要。
为解决泊车系(用外文写>
统如何通过新技术和新方法更有效地运作的问题,本文旨在讨论停车场规划和管理地理信息系统在大都市的交通运行效率方面的应用。
本文要点集中包括停车需求特点和停车难的问题,尤其对解决停车的问题的基本原理和策略做了详细阐述,并从地理信息系统的角度进行了大量详细的停车问题分析。
1. 介绍
如今,停车难的问题一直是广大市民讨论最多的话题之一。
在许多城市,停车问题日益严重。
随着交通需求的快速增长,停车供应与停车需求失衡一直被视为城市停车问题的主要原因。
此外,停车系统在城市中起着关键的作用。
停车问题与交通系统、交通拥堵、交通事故,环境污染息息相关。
停车问题促使交通专业人士迫切寻求更有效的解决方案,比如停车系统如何更有效地使用,怎样通过新技术和新方法的改进停车场的规划和管理。
近年来,地理信息系统<GIS)因为其对解决停车问题具有功能强大的技术潜力,而受到广泛的关注。
地理信息系统是最好的利用各种数据集合以获得均匀的复合土地整合的开发单位。
这有助于识别问题区域,提出保护措施和解决方法。
GIS技术在运输建模方面也有极为重要的作用。
GIS的传播有利于高效地应用便携式的空间数据进行存储,更新和处理。
在现有交通规划的情况下,总需求的满足必须有可靠的运输服务做保证,以最小化的外部成本均衡与道路交通的其他相关利益。
随着互联网技术的发展,基于Web的GIS应用到了交通环境分析规划和管理,并实现GIS-T系统的Web,Java和CORBA技术进行探讨。
GIS在机动车停车场的研究是可取的,因为它与地理位置密切相关。
GIS技术的发展为城市停车场规划与决策开辟了新的途径。
针对利用GIS技术提高规划停车场管理的目标,本文讨论了城市停车问题相应的解决方案,并对停车需求、停车的原因和特点问题进行了研究。
后然进行对基本停车的原则和解决停车问题的策略性的建议,通过北京停车的具体案例研究地理信息系统的应用。
2.北京的停车的关键问题
北京停车问题的主要原因可以归结为停车设施和停车需求的供应之间的差距。
停车位的需求是十分迫切的,这可以解释为较高的增长速度,高强度的使用,和高密度的车流聚集导致的。
分析北京的停车问题的关键问题,有如下几方面的特点:机动车辆的迅速增长和新的停车设施有限之间的差距直接导致停车困难。
自2004
以来,北京私家车的数量每年增长34万辆。
与此同时,新的停车设施供应,包括路边停车场和路外停车位的供应每年却只增加10万,更别说停车位的历史遗留不足了。
在北京,尖锐的停车位的需求和供给之间的差距逐年拉大。
因此,停车问题似乎是越来越严重了。
必须指出,设备使用率低加重了停车问题。
因或多或少地涉及经济,和司机的个性特点,有一些停车设施经常被占用,而有一些则不经常使用。
以商业中心王府井和西单为例,20%到30%的地下公共停车场处于闲置状态。
而设计在路边的停车位使用率却高达120%到150%。
这种现象是非常常见的。
不幸的是,更多的路边停车位分布在小路和胡同系统,这些道路的停车容量急剧减少。
道路越是狭窄,一些人就越是占用道路空间进行路边停车,这个矛盾开始促成了一个新的恶性循环。
停车管理的专业性缺乏是另一个停车问题。
目前在北京,不按规则运营,或是违反交通规则的停车场将罚款200元,但是没有扣除运输信用点。
众所周知,因不规则停车被发现罚款的几率很低。
总之,城市不规则停车处罚力度小从而无形中就增加了机会成本。
相比之下,在其他大城市,例如日本,不规则停车将受到严格惩罚并记录在案。
一个有趣的现象是,机动车辆特别密集的北京,大部分是公务车。
车辆电机的集约化利用导致了停车位高需求的同时,也增加了空间的分布不均匀与需求方面的矛盾。
在上下班的时间,驶出车库和停车场的很大一部分车需要占用很长的时间,因此,累计停车的时间是比较长的。
全天对停车位的需求保持在特定的时间间隔之内,总的来说,一天之中停车供给与需求之间是均匀分布的。
在更密集的交通情况下,非专业停车管理让停车面临的需求更加恶化。
3.停车场规划与管理案例研究
停车场规划问题中,新的停车设施的需要应针对现有附近的停车设施考虑。
通过GIS强大的功能,它会让驾驶员与新的停车设施的需要相联系。
不仅对现有的附近的停车设施可用性做出判断,并且通过拓扑关系检查接近。
通过ArcGIS软件平台,我们在一个城市提供决策支持的停车管理设施项目。
GIS停车设施管理和停车场的规划过程如下:
步骤1:确定输入数据集。
在这种情况下如图2 ,输入数据包括道路网络布局,交通区的布局,和一些调查数据。
例如,停车时间,停车类型。
步骤2。
导出数据。
在这种情况下,派生的数据集包括停车场分布,停车费用,停车时间等。
举个例子,停车类型分布在图3所示。
在图中,数字1到9表示不同的停车类
型,如路边停车场,公共的越野停车场,小区停车设施,复合单位,和临时停车场。
步骤3。
重新分类数据。
该数据集的分类,根据现有的停车场设施,停车场,分布类型,等等。
如图4,。
步骤4。
衡量和整合数据。
通过GIS空间分析,不同的权重被分配到的数据集,以确定出何为最严重的停车场停车问题。
它可以帮助决定未来规划和建设停车设施。
图5将能够非常直观的反映城市的停车的情况。
作为一个结果,它可为制定相关政策和措施提供支持,并有助于停车问题的决策与管理。
4.总结
就像交通堵塞、交通事故、环境污染,停车问题是城市在城市化和机动化发展过程中产生的主要问题。
这些问题是汽车需求过剩和环境条件之间矛盾的集中表现。
纽约、伦敦、东京以及其他主要城市等在城市化进程中,也面临着严重的停车问题。
这些问题导致频繁的交通拥堵和交通事故,以至于给居民的生活造成巨大影响。
因此,停车场管理是调节机动程序的重要手段。
要意识到停车场问题是停车难解决的主要方面,使用技术手段宣传很有必要。
即使是最有效的停车场程序,都会发觉与群众交流越来越具有挑战性。
在大城市,向市民普及停车相关法律法规的重要性是很有必要的。
引导和牵引程序发送高度可见的消息给其他人后果会很严重。
大城市已采取引导和牵引大众对GIS应用的进行进一步使用的措施。
GIS Web应用数据挖掘的信息存储在停车场管理信息系统的数据仓库,这些数据可以提供额外的管理研究。
通过地理信息系统,用户可以直观地看到特性,数据,信息重叠的底图。
通过使用地理信息系统软件的功能,数据可以比较,可以识别趋势,可以开发进一步的行动计划。
