Thedevelopmentofmanagement(新)
“The development of management”●Introduction:The Industrial Revolution separated us from the pre-modern era. After the dramatic change crossed the Atlantic to other parts of the world, it brought about the development of large organizations, so the theory for coping with the problems arose in running the organizations was needed. In consequence, there were theories stemmed from different times and focused on distinct aspects regarding management. However, two approaches, which are called the classical perspective and the human relations perspective, are the significant sector of management. Furthermore, they described different portion of management and both had great influences on the development of management.●The Classical Perspective:The theory of classical perspective developed about the end of the nineteenth century. In order to manage organizations more efficient, a group of innovators sought to the general principles as the theoretical foundation for management. Additionally, the classical perspective approach can be divided into three subcategories: scientific management, bureaucracy and administrative principles.1.Scientific managementThe theory stressed on operations and on treating individuals as machines. For thesake of describing the system, several pioneers struggled to carry out a rational approach as followings:1) Frederick W. Taylor: “Father of Scientific Management”Taylor created a clear guideline for improving production efficiency by using scientific techniques, which was called Taylorism. He advocated four principles of management which could be briefly described as followings: to discover the most efficient techniques of performing for each specific work factors to train, teach and develop the matching workers, and to ensure that they adopt the scientific methods to perform the task with a pay system that provides a reward for performance. Meanwhile, the work and responsibility needed to be reasonably distributed between the managers and workers. Furthermore, he thought up six key ideas that dovetailed nicely into the four principles. In conclusion, Taylor’s work has had a profound and lasting effect on the management of production systems and an extreme success from the economic standpoint. Thus, the initial attempt to use scientific management techniques was an access to the era of modern management.1)Frank Gilbreth and Lillian GilbrethThe Gilbreths reported on the motion-time study in order to facilitate the work process, so they investigated the bricklaying performance in motion picture films. After studying the motions, they eliminated wasted motions for the sake of shortening the work time. Compared with the observation of Taylor, the Gilbreths’ motion studywas more specific and wide.2) Henry GanttGantt, a colleague of Taylor, was a young engineer. He was noted for the Gantt chart—a planning chart expressed by lines that currently is used as a scheduling device. Besides, Gantt developed Taylor’s original ideas and simultaneously added a few of his own. For instance, he paid a bonus to the workers who completed their jobs over the standard by results, which added to the job salary whereas Taylor’s payment by results because this solution can provide a guarantee for workers and improve the enthusiasm.2.BureaucracyBureaucracy was to look at the problem of managing the organizations as a whole for organizational structure. Nevertheless, this theory also emphasized the organizations envisioned as a mechanism for achieving its goals in the most efficient way. The key participant is Max Weber.Max WeberAt almost the same time, while scientific management studied for industrial operation, Weber was endeavoring to observe the social problems. He formulated the rational-legal model of organizations rather than the charismatic and traditional models, so he argued that rationality, which he adopted and named this type ofauthority as bureaucracy, would replace blind worship and feudal custom and practice. In addition, he explained the principles of ideal-typical bureaucracy which encompassed six characteristics. At last, Weber believed that the depersonalized and legitimate type of organizations was a more efficient form for enforcing control and coping with variation tendency. The system, which was advanced in accuracy, stability and discipl inary rules, became a standard for many of today’s large organizations. Yet the bureaucratic superstructure laid stress on efficiency and hierarchy and ignored the “group dynamics” and innovation, limit ed the bureaucracy’s potential development.3.Administrative principlesAdministrative principles concentrated on general process of management. Henry Fayol and Mary Parker Follett were two prominent individuals who helped to develop general administrative theory.1) Henry FayolFayol’s theories of administrat ion were connected to bureaucracy thought up by Weber, which highlighted the personal duties of management while Weber laid out principles for a whole authority structure. Meanwhile, His attention was directed at the performance of managers whereas Taylor contributed to management at the supervisor level on account of their subjective experience. Besides, Fayol was best known by three themes:●Five principle rolesFayol defined that “manage is to forecast and plan, to organize, to command, to co-ordinate an d to control”, which was the competence required of managers.●14 general principles of managementFayol designated them to apply to every need as a universal standard. Sificantly, the last principles initiative and team spirit are the two exceptions to Web er’s theory. Weber restrained the interaction and communication between the groups while Fayol definitely claimed the esprit vitality was meaningful to supply the ideal structure.●Five elements of managementFayol then proceeded to state the elements that were some part of his definition of management and described the importance of seeking to appropriate method to train people and the personal abilities to give commands and management.Although Fayol’s themes now are deemed as out of date and criticized for unsuitable for the specific operation, his five principle roles of management are still active today even taught in schools and universities as a lecture. With other scholars’ efforts, the administrative principles have been continually upgraded and practiced.1)Mary Parker FollettFollett was another who highlighted the necessity for general principles; however, shedissimilarly realized the needs, abilities, and aspirations of employees. Simultaneously, she mentioned that people were not supposed to be paralleled as machines. Therefore, Follett’s attitude of the humanist provided a bridge to later views.The classical perspective emphasized the efficiency and mass production but neglected the social context and psychological needs of employees, which would inevitably result in the depression surroundings. What’ more, members gradually united as an informal group consequent on organizational power that was much stronger than the pressure of management. At the same time, the emerging influence of trade unions, further studies and humanism philosophy enlightened employers became attracted by human relations ideas.Human Relations PerspectiveDuring the 1920s, managers turned their concentration towards the organization’s human resources management. As a result, the observation of theorists what we has characterized as the human relations approach appeared. There are numerous individuals who recognized the value of the human factor.1. Elton MayoMayo conducted the Hawthorne Studies to examine the impact of work condition in employee productivity, which grew out of preliminary experiments on the effect of different illumination levels on worker productivity. After three studies on the relay assembly test room, the bank wiring observation room and the interview programme,the following conclusions were the result of his studies:1) The worker is a social not economic person. Except of the substantive interests, the need for social recognition and psychology significantly affects individual behavior.2) The informal organizations and work-group norms affect output. With working together, the members would perform a conventional sentimental tendency and then form the norms, after which became a system called “informal organizations” influencing the members’ job behavio r. Additionally, relations that leaders developed with workers had a dramatic impact on the productivity.3) Job attitude and relationship influence the work performance. Mayo stressed on employee satisfaction that would improve the initiative and activity for work.1.Need theory1)Abraham MaslowMaslow proposed a hierarchy of five needs: self- actualization, self- esteem needs, love and relationship needs, security needs and biological needs. He argued that the need that had been satisfied was useless to motivation and each step in the hierarchy must be satisfied before the next level can be motivated. Nowadays, the hierarchy of needs theory is still known as the famous theory of general motivation.2)Frederick HerzbergHerzberg designated the motivation-hygiene theory which described the relationship between individuals and work. He concluded that motivator factors most internal could increase the job satisfaction whereas the hygiene factors most external if that lacked could create job dissatisfaction. So the managers should first deal with the hygiene factors and then use the motivator factors to stimulate the initiative of employees for achieving the goals.3)David McClellandMcClelland suggested that people seldom inherently had the need for achievement, power and affiliation but obtained after living experience. Obviously, people who are strongly willing to possess power are most likely to become the leader of the organization. Compared with it, the people who have the need for achievement prefer to choose moderate risk, so they tend to become the manager with a lower power. On the other hand, people need for affiliation inclined to live in a cooperative not competitive surroundings.2.Douglas McGregorMcGregor had a reputation for his formulation of two kinds of assumption about human nature—Theory X and Theory Y. Theory X describe a negative viewpoint of workers, assuming that people inherently dislike work and will avoid the responsibility, and even people need to be directed and pushed to work. On the other hand, Theory Y presents a positive viewpoint, assuming that people enjoy work, andperforms self-direction and self-control with acceptance of responsibility. Ultimately, McGregor chose the Theory Y as the best guideline towards management practice. 3.John AdamsHe believed that an employee compared his job inputs-outcomes ratio with that of referents, so this comparison was a motivation to pursuit fairness and equity. If the employee perceives inequity, he will act to correct it. Consequently, the manager has the need for improving the management system in case of employee dissatisfaction. The setback of equity theory is that employees evaluate the equity from the standpoint of their own, which exerts a great pressure on managers.4.Victor VroomThe expectancy theory stressed on outcome and reported that only when people expected the performance followed by an attractive reward, they would perform in a particular manner. According to the theory, the motivation is influenced by expectancy and valence. Expectancy is the estimate whether better efforts will result in better performance; on the other hand, valence is the significance associated by an individual about the expected outcome. Thus, the responsibility of managers is to assist employees attaining their goals as well as the organizations'. In the meantime, deserving employees must be rewarded for their exceptional performance in order to improve the initiative and activity.ConclusionInnovators of human relations perspective collectively believed in the significance of employee satisfaction distinct from the classic perspective. Certainly, with the development of management, other approaches which merged into much of management theory also made contributions to the progress such as the management science perspective, integrating perspectives, and the contingency perspective. The whole system evolved to reflect the changing needs of organizations and society, so we would consider the management history as a non-stop process.。

顺应产业链式发展趋势英文
顺应产业链式发展趋势英文The Trend of Industry Chain Development and its Implications IntroductionIn recent years, the concept of industry chain has gained significant attention in the field of business and economics. With the rapid development of technology and globalization, businesses are becoming increasingly interconnected through various stages of production and distribution. This interconnectedness forms the basis of the industry chain, which is a series of vertically and horizontally linked activities that contribute to the final product or service. As such, the industry chain has become an important factor in determining the competitiveness of a country or region in today's global economy. This essay will explore the trend of industry chain development and its implications on various sectors and actors.1. The Evolution of Industry ChainsThe concept of industry chains can be traced back to the early 20th century when industrialization was on the rise and businesses started to organize their production processes vertically. However, it was not until the late 20th century that the complexity and interdependence of industry chains became more apparent. The advent of information and communication technologies, as well as the growth of global trade, facilitated the integration of production and distribution activities across borders. This led to the emergence of global value chains (GVCs), which refers to the international division of labor where different stages of production take place indifferent countries.The evolution of industry chains can be seen in various sectors. For example, in the manufacturing sector, the traditional industry chain involves raw material extraction, component manufacturing, product assembly, and distribution. However, with the advancement of technology and the increasing importance of services, the industry chain has expanded to include design, research and development, marketing, and after-sales services. Similarly, in the agricultural sector, the industry chain now encompasses activities such as farming, processing, packaging, transportation, and retail. The evolution of industry chains has led to the creation of new business models and the emergence of service-based economies.2. Benefits and Challenges of Industry ChainsThe development of industry chains brings about several benefits. Firstly, it promotes specialization and efficiency by allowing businesses to focus on their core competencies. Through outsourcing and subcontracting, firms can take advantage of economies of scale and scope, reducing costs and improving quality. Secondly, industry chains facilitate innovation and technological advancements. By collaborating with partners along the chain, businesses can share knowledge and resources, leading to the development of new products and processes. Thirdly, industry chains promote economic development by attracting foreign direct investment and creating employment opportunities. By participating in global value chains, countries can integrate into the global economy and benefit from the transfer of technologyand know-how.However, the development of industry chains also poses challenges. Firstly, there is a risk of over-reliance on foreign partners and vulnerability to supply chain disruptions. Global value chains are susceptible to external shocks, such as natural disasters, political instability, and trade disputes. Secondly, industry chains require effective coordination and communication among stakeholders. Due to differences in language, culture, and legal systems, collaboration across borders can be complex and time-consuming. Thirdly, industry chains may lead to income inequality and social tensions. The concentration of value-added activities in certain regions or countries can result in uneven distribution of benefits, widening the gap between the rich and the poor.3. Implications of Industry Chain DevelopmentThe development of industry chains has profound implications for various sectors and actors.3.1. Implications for BusinessesFor businesses, the industry chain presents both opportunities and challenges. On one hand, companies can leverage the industry chain to enhance their competitiveness. By specializing in specific stages of production or by developing innovative business models, firms can create value and differentiate themselves from competitors. For example, in the computer industry, companies like Apple have established an integrated industry chain by controlling everything from design to retail, enabling them todeliver a seamless customer experience. On the other hand, businesses need to adapt to the changing dynamics of industry chains. They should continuously improve their processes, invest in research and development, and build strategic partnerships to stay relevant. With the increasing demand for sustainability, businesses should also consider environmental and social factors in their value chains.3.2. Implications for GovernmentsGovernments play a crucial role in promoting and regulating the development of industry chains. They need to create a conducive business environment by providing infrastructure, education and training, and access to finance. Governments should also formulate policies that support innovation and entrepreneurship, such as tax incentives and research grants. Furthermore, governments need to establish effective governance mechanisms to ensure fair competition, protect intellectual property rights, and enforce labor and environmental standards. In the era of global value chains, governments should also actively participate in regional and international trade agreements to secure access to global markets and protect the interests of domestic industries.3.3. Implications for WorkersThe development of industry chains has both positive and negative consequences for workers. On one hand, industry chains create employment opportunities by attracting investments and facilitating the expansion of businesses. In developing countries, the establishment of export-oriented industries has led to jobcreation and poverty reduction. On the other hand, industry chains can lead to job insecurity and the displacement of workers. Technology advancements and automation have resulted in the replacement of labor-intensive jobs with machines. In addition, industry chains may lead to labor exploitation and poor working conditions, especially in low-cost production countries. To address these challenges, workers need to acquire new skills and adapt to changing demands. Governments and businesses should also invest in social protection and promote responsible business practices to ensure the welfare and rights of workers.3.4. Implications for SustainabilityThe development of industry chains has significant implications for sustainability. On one hand, industry chains provide opportunities for businesses to adopt sustainable practices throughout their value chains. For example, by sourcing ethically and environmentally responsible raw materials, companies can contribute to the conservation of natural resources and reduce pollution. On the other hand, industry chains can lead to environmental degradation and carbon emissions. The transportation of goods across long distances contributes to greenhouse gas emissions and air pollution. Additionally, the pursuit of cost efficiency may lead to the exploitation of natural resources and the degradation of ecosystems. Therefore, it is crucial for businesses, governments, and stakeholders to work together to promote sustainable consumption and production patterns and to develop policies that encourage the adoption of green technologies and practices.ConclusionThe development of industry chains has become an integral part of our globalized economy. As businesses become increasingly interconnected, the industry chain has evolved and expanded to encompass various sectors and activities. Although industry chains bring about benefits such as specialization, efficiency, and innovation, they also pose challenges such as supply chain disruptions, coordination issues, and social inequalities. Therefore, businesses, governments, workers, and other stakeholders need to adapt to the changing dynamics of industry chains and work together to promote inclusive and sustainable development. By doing so, we can harness the potential of industry chains to drive economic growth, improve living standards, and address global challenges.。
标准助推第四次工业革命
Standards facilitate the Fourth Industrial Revolution 专访德国电气电子信息技术委员会(DKE)总裁迈克尔·泰格勒Interview with Mr. Michael Teigeler, Managing Director of German Commission Electrical and Electronic Information Technology in DIN andVDE (DKE)标准助推第四次工业革命BETTER COMMUNICATION | GREATER VALUEIndustry 4.0 represents the Fourth Industrial Revolution. What is Industry 4.0 in your opinion? What is German standardization strategy in this process?Mr. Michael Teigeler: The fourth industrial revolution will affect the whole eco-system of the manufacturing industry. The previous industrial revolutions changed the way how products have been produced in a vertical dimension, with other aspects remained more or less unchanged. In the fourth industrial revolution, we will see an extended value chain connecting smart factories, smart products and smart services. These three dimensions form the three axis of the Reference Architecture Model “Industrie 4.0” (RAMI 4.0), a model which has been introduced by German experts and will guide the standardization work worldwide.The central building blocks of this process are seamless data structures. For example, the concept of “Digital Twin” foresees a complete digital representation of a product or system throughout its entire life cycle. This digital representation monitors in real time key requirements on interoperability, safety and security are conform to standards, which can be tested virtually. New services can also be created to extend the values of standardization and better serve industry and consumer needs.You said that the Standardization Council Industry 4.0 is the linchpin of the process in your presentation at the international symposium on standardization strategies held in Beijing in November 2018. Could you tell us a little more about it?The concept of “Industrie 4.0” covers many areas which have been treated in silos in the past, also for standardization work. Today, standardization activities need to be coordinated to interlink different aspects across functions and sectors. Therefore the Standardization Council “Industrie 4.0” was established. There are several key tasks. First, there is a need to initiate and coordinate the development of digital production standards at national and international level. This requires liaising with industry and standardization bodies, i.e. to coordinate the needs between the stakeholders represented through the German “Industrie 4.0” platform and the various standards developing organizations (SDOs). Second, the Standardization Council “Industrie 4.0” aims to facilitate the creation of international standards through, for example, partnering with ISO and IEC, and through regular technical discussion in the Sino-German standardization cooperation commission and the established Sub Working Group Smart Manufacturing/Industry 4.0.Moreover, the SCI 4.0 collaborates with pilot projects, which enables quick and tailored standardization activities utilizing the findings of these initiatives.Finally the Standardization Council “Industrie 4.0” coordinates the draft of Standardization Roadmap “Industrie 4.0”.The German Standardization Roadmap Industrie 4.0, released by DIN, DKE and VDE, is the most dowloaded document in the online library and highly interested by China. Could you introduce more about it? What benefits can it bring to industries and consumers across the globe?Standardization roadmaps address several targets. First of all they give an overview on the current standardization landscape. This includes the different players like standardization organizations and technical committees but also the different existing standards and ongoing standardization projects. Secondly the roadmap identifies needs for new standards based on a gap analysis. Recommendations for standardization work are derived based on this step. Altogether the roadmap describes the German standardization strategies to achieve “Industrie 4.0”. The roadmap is not a static document. It is written by a large number of technical experts from various disciplines and it is updated bi-annually.DKE is a trusted platform for standardization, cooperation and interaction of experts in the areas of electrical engineering, electronics and information technologies. How does DKE encourage SMEs to access standards and participate in standardization?BETTER COMMUNICATION | GREATER VALUEFirst of all, DKE provides a level playing field for all technical experts regardless they are from a global enterprise or a SME. The participation in DKEs work is free of charge which is another benefit especially for SMEs.Additionally DKE offers free trainings to technical experts, including those from SMEs. We are as well offering a tailored program to ease the access to standards for SMEs, a help desk to support experts particularly from SMEs in participation in standardization activities, as well as tools to guide the use of standards.Reciprocally, SMEs also see the benefit by being active in drafting new standards.What benefits can SMEs receive in the participation in standardization?Typically SMEs have excellent know how about a specific technology. But due to their size they cannot cover all technical aspects of “Industrie 4.0”. Through participation in standardization, companies can make sure that their specific technology is recognized and forms part of a standard. In other words even SMEs can influence the wording of requirements in a standard in a way which supports the application of their specific technology.Another benefit is to sense technical trends through participation in standardization. For example if a new safety concept is adopted in a safety standard you can adapt the market introduction of new products to the foreseeable introduction of such a standard. As a consequence we see many ofthe German “hidden champion” SMEs in our technical committees.。

模具的发展--中英文翻译
Die history1 Die position in industrial productionMold is a high-volume products with the shape tool, is the main process of industrial production equipment.With mold components, with high efficiency, good quality, low cost, saving energy and raw materials and a series of advantages, with the mold workpieces possess high accuracy, high complexity, high consistency, high productivity and low consumption , other manufacturing methods can not match. Have already become an important means of industrial production and technological development. The basis of the modern industrial economy.The development of modern industrial and technological level depends largely on the level of industrial development die, so die industry to national economic and social development will play an increasing role. March 1989 the State Council promulgated "on the current industrial policy decision points" in the mold as the machinery industry transformation sequence of the first, production and capital construction of the second sequence (after the large-scale power generation equipment and the corresponding power transmission equipment), establish tooling industry in an important position in the national economy. Since 1997, they have to mold and its processing technology and equipment included in the "current national focus on encouraging the development of industries, products and technologies catalog" and "to encourage foreign investment industry directory." Approved by the State Council, from 1997 to 2000, more than 80 professional mold factory owned 70% VAT refund of preferential policies to support mold industry. All these have fully demonstrated the development of the State Council and state departments tooling industry attention and support. Mold around the world about the current annual output of 60 billion U.S. dollars, Japan, the United States and other industrialized countries die of industrial output value of more than machine tool industry, beginning in 1997, China's industrial output value has exceeded the mold machine tool industry output.2 China's mold industry and its development trendDie & Mould Industry StatusDue to historical reasons for the formation of closed, "big and complete" enterprise features, most enterprises in China are equipped with mold workshop, in factory matching status since the late 70s have a mold the concept of industrialization and specialization of production. Production efficiency is not high, poor economic returns. Mold production industry is small and scattered, cross-industry,capital-intensive, professional, commercial and technical management level are relatively low.According to incomplete statistics, there are now specialized in manufacturing mold, the product supporting mold factory workshop (factory) near 17 000, about 600 000 employees, annual output value reached 20 billion yuan mold. However, the existing capacity of the mold and die industry can only meet the demand of 60%, still can not meet the needs of national economic development. At present, the domestic needs of large, sophisticated, complex and long life of the mold also rely mainly on imports. According to customs statistics, in 1997 630 million U.S. dollars worth of imports mold, not including the import of mold together with the equipment; in 1997 only 78 million U.S. dollars export mold. At present the technological level of China Die & Mould Industry and manufacturing capacity, China's national economy in the weak links and bottlenecks constraining sustainable economic development. 2.1 Research on the Structure of industrial products moldIn accordance with the division of China Mould Industry Association, China mold is divided into 10 basic categories, which, stamping die and plastic molding two categories accounted for the main part. Calculated by output, present, China accounts for about 50% die stamping, plastic molding die about 20%, Wire Drawing Die (Tool) about 10% of the world's advanced industrial countries and regions, the proportion of plastic forming die die general of the total output value 40%.Most of our stamping die mold for the simple, single-process mode and meet the molds, precision die, precision multi-position progressive die is also one of the few, die less than 100 million times the average life of the mold reached 100 million times the maximum life of more than accuracy 3 ~ 5um, more than 50 progressive station, and the international life of the die 600 million times the highest average life of the die 50 million times compared to the mid 80s at the international advanced level. China's plastic molding mold design, production technology started relatively late, the overall level of low. Currently a single cavity, a simple mold cavity 70%, and still dominant. A sophisticated multi-cavity mold plastic injection mold, plastic injection mold has been able to multi-color preliminary design and manufacturing. Mould is about 80 million times the average life span is about, the main difference is the large deformation of mold components, excess burr side of a large, poor surface quality, erosion and corrosion serious mold cavity, the mold cavity exhaust poor and vulnerable such as, injection mold 5um accuracy has reached below the highest life expectancy has exceeded 20 million times, the number has more than 100 chamber cavity, reaching the mid 80s to early 90s the international advanced level.2.2 mold Present Status of TechnologyTechnical level of China's mold industry currently uneven, with wide disparities. Generally speaking, with the developed industrial countries, Hong Kong and Taiwan advanced level, there is a large gap.The use of CAD / CAM / CAE / CAPP and other technical design and manufacturemolds, both wide application, or technical level, there is a big gap between both. In the application of CAD technology design molds, only about 10% of the mold used in the design of CAD, aside from drawing board still has a long way to go; in the application of CAE design and analysis of mold calculation, it was just started, most of the game is still in trial stages and animation; in the application of CAM technology manufacturing molds, first, the lack of advanced manufacturing equipment, and second, the existing process equipment (including the last 10 years the introduction of advanced equipment) or computer standard (IBM PC and compatibles, HP workstations, etc.) different, or because of differences in bytes, processing speed differences, differences in resistance to electromagnetic interference, networking is low, only about 5% of the mold manufacturing equipment of recent work in this task; in the application process planning CAPP technology, basically a blank state, based on the need for a lot of standardization work; in the mold common technology, such as mold rapid prototyping technology, polishing, electroforming technologies, surface treatment technology aspects of CAD / CAM technology in China has just started. Computer-aided technology, software development, is still at low level, the accumulation of knowledge and experience required. Most of our mold factory, mold processing equipment shop old, long in the length of civilian service, accuracy, low efficiency, still use the ordinary forging, turning, milling, planing, drilling, grinding and processing equipment, mold, heat treatment is still in use salt bath, box-type furnace, operating with the experience of workers, poorly equipped, high energy consumption. Renewal of equipment is slow, technological innovation, technological progress is not much intensity. Although in recent years introduced many advanced mold processing equipment, but are too scattered, or not complete, only about 25% utilization, equipment, some of the advanced functions are not given full play.Lack of technology of high-quality mold design, manufacturing technology and skilled workers, especially the lack of knowledge and breadth, knowledge structure, high levels of compound talents. China's mold industry and technical personnel, only 8% of employees 12%, and the technical personnel and skilled workers and lower the overall skill level. Before 1980, practitioners of technical personnel and skilled workers, the aging of knowledge, knowledge structure can not meet the current needs; and staff employed after 80 years, expertise, experience lack of hands-on ability, not ease, do not want to learn technology. In recent years, the brain drain caused by personnel not only decrease the quantity and quality levels, and personnel structure of the emergence of new faults, lean, make mold design, manufacturing difficult to raise the technical level.2.3 mold industry supporting materials, standard parts of present condition Over the past 10 years, especially the "Eighth Five-Year", the State organization of the ministries have repeatedly Material Research Institute, universities and steel enterprises, research and development of special series of die steel, molds and othermold-specific carbide special tools, auxiliary materials, and some promotion. However, due to the quality is not stable enough, the lack of the necessary test conditions and test data, specifications and varieties less, large molds and special mold steel and specifications are required for the gap. In the steel supply, settlement amount and sporadic users of mass-produced steel supply and demand contradiction, yet to be effectively addressed. In addition, in recent years have foreign steel mold set up sales outlets in China, but poor channels, technical services support the weak and prices are high, foreign exchange settlement system and other factors, promote the use of much current.Mold supporting materials and special techniques in recent years despite the popularization and application, but failed to mature production technology, most still also in the exploratory stage tests, such as die coating technology, surface treatment technology mold, mold guide lubrication technology Die sensing technology and lubrication technology, mold to stress technology, mold and other anti-fatigue and anti-corrosion technology productivity has not yet fully formed, towards commercialization. Some key, important technologies also lack the protection of intellectual property.China's mold standard parts production, the formation of the early 80s only small-scale production, standardization and standard mold parts using the coverage of about 20%, from the market can be assigned to, is just about 30 varieties, and limited to small and medium size. Standard punch, hot runner components and other supplies just the beginning, mold and parts production and supply channels for poor, poor accuracy and quality.3 Die trend3.1 mold CAD / CAE / CAM being integrated, three-dimensional, intelligent and network direction(1) mold software features integratedDie software features of integrated software modules required relatively complete, while the function module using the same data model, in order to achieve Syndicated news management and sharing of information to support the mold design, manufacture, assembly, inspection, testing and production management of the entire process to achieve optimal benefits. Series such as the UK Delcam's software will include a surface / solid geometric modeling, engineering drawing complex geometry, advanced rendering industrial design, plastic mold design expert system, complex physical CAM, artistic design and sculpture automatic programming system, reverse engineering and complex systems physical line measurement systems. A higher degree of integration of the software includes: Pro / ENGINEER, UG and CATIA, etc.. Shanghai Jiaotong University, China with finite element analysis of metal plastic forming systems and Die CAD / CAM systems; Beijing Beihang HaierSoftware Ltd. CAXA Series software; Jilin Gold Grid Engineering Research Center of the stamping die mold CAD / CAE / CAM systems .(2) mold design, analysis and manufacture of three-dimensionalTwo-dimensional mold of traditional structural design can no longer meet modern technical requirements of production and integration. Mold design, analysis, manufacturing three-dimensional technology, paperless software required to mold a new generation of three-dimensional, intuitive sense to design the mold, using three-dimensional digital model can be easily used in the product structure of CAE analysis, tooling manufacturability evaluation and CNC machining, forming process simulation and information management and sharing. Such as Pro / ENGINEER, UG and CATIA software such as with parametric, feature-based, all relevant characteristics, so that mold concurrent engineering possible. In addition, Cimatran company Moldexpert, Delcam's Ps-mold and Hitachi Shipbuilding of Space-E/mold are professional injection mold 3D design software, interactive 3D cavity, core design, mold base design configuration and typical structure . Australian company Moldflow realistic three-dimensional flow simulation software MoldflowAdvisers been widely praised by users and applications. China Huazhong University of Science have developed similar software HSC3D4.5F and Zhengzhou University, Z-mold software. For manufacturing, knowledge-based intelligent software function is a measure of die important sign of advanced and practical one. Such as injection molding experts Cimatron's software can automatically generate parting direction based parting line and parting surface, generate products corresponding to the core and cavity, implementation of all relevant parts mold, and for automatically generated BOM Form NC drilling process, and can intelligently process parameter setting, calibration and other processing results.(3) mold software applications, networking trendWith the mold in the enterprise competition, cooperation, production and management, globalization, internationalization, and the rapid development of computer hardware and software technology, the Internet has made in the mold industry, virtual design, agile manufacturing technology both necessary and possible. The United States in its "21st Century Manufacturing Enterprise Strategy" that the auto industry by 2006 to achieve agile manufacturing / virtual engineering solutions to automotive development cycle shortened from 40 months to 4 months.3.2 mold testing, processing equipment to the precise, efficient, and multi-direction(1) mold testing equipment more sophisticated, efficientSophisticated, complex, large-scale mold development, testing equipment have become increasingly demanding. Precision Mould precision now reached 2 ~ 3μm, more domestic manufacturers have to use Italy, the United States, Japan and other countries in the high-precision coordinate measuring machine, and with digital scanning. Such as Dongfeng Motor Mould Factory not only has the capacity3250mm ×3250mm Italian coordinate measuring machine, also has a digital photography optical scanner, the first in the domestic use of digital photography, optical scanning as a means of spatial three-dimensional access to information, enabling th e establishment from the measurement of physical → model output of engineering drawings → → the whole process of mold making, reverse engineering a successful technology development and applications. This equipment include: second-generation British Renishaw high-speed scanners (CYCLON SERIES2) can be realized and contact laser probe complementary probe, laser scanner accuracy of 0.05mm, scanning probe contact accuracy of 0.02 mm. Another German company GOM ATOS portable scanners, Japan Roland's PIX-30, PIX-4 desktop scanner and the United Kingdom Taylor Hopson's TALYSCAN150 multi-sensor, respectively Three-dimensional scanner with high speed, low-cost and functional composite and so on.(2) CNC EDMJapan Sodick linear motor servo drive using the company's AQ325L, AQ550LLS-WEDM have driven fast response, transmission and high positioning accuracy, the advantages of small thermal deformation. Switzerland Chanmier company NCEDM with P-E3 adaptive control, PCE energy control and automatic programming expert systems. Others also used the powder mixed EDM machining technology, micro-finishing pulse power and fuzzy control (FC) technologies.(3) high-speed milling machine (HSM)Milling is an important means of cavity mold. The low-temperature high-speed milling with the workpiece, cutting force is small, smooth processing, processing quality, processing efficiency (for the general milling process 5 to 10 times) and can process hard materials (<60HRC) and many other advantages. Thus in the mold processing more and more attention. Ruishikelang company UCP710-type five-axis machining center, machine tool positioning accuracy up to 8μm, home-made closed-loop vector control spindle with a maximum speed 42000r/min. Italy RAMBAUDI's high-speed milling, the processing range of up to 2500mm × 5000mm × 1800mm, speed up 20500r/min, cutting feed speed of 20m/min. HSM generally used large, medium-sized mold, such as motor cover mold, die casting mold, large plastic surface machining, the surface precision up to 0.01mm.3.3 mold materials and surface treatment technology developed rapidly Industry to the level of mold, material application is the key. Due to improper selection and use of materials, causing premature die failure, which accounts for more than 45% failure die. In the mold material, commonly used cold work tool steel with CrWMn, Cr12, Cr12MoV and W6Mo5Cr4V2, flame hardened steel (such as Japan, AUX2, SX105V (7CrSiMnMoV), etc.; used a new type of hot work die steel American H13, Sweden QRO80M, QRO90SUPREME, etc.; used a pre-hardened plastic mold steel (such as the U.S. P20), age-hardening steel (such as the U.S. P21, Japan NAK55, etc.), heat treatment hardened steel (such as the United States, D2,Japan, PD613, PD555, Sweden wins the White 136, etc.), powder die steel (such as Japan KAD18 and KAS440), etc.; panel drawing die used HT300, QT60-2, Mo-Cr, Mo-V cast iron, large-scale mold with HT250. more regular use of Precision Die Hard Steel Results YG20 and other alloys and carbide. in the mold surface treatment, the main trends are: the infiltration of a single element to the multi-element penetration, complex permeability (such as TD method) development; by the general diffusion to the CVD, PVD, PCVD, ion penetration , the direction of ion implantation, etc.; can use the coating are: TiC, TiN, TiCN, TiAlN, CrN, Cr7C3, W2C, etc., while heat from the air treatment means to the development of vacuum heat treatment. In addition, the current strengthening of the laser, glow plasma Nitriding and electroplating (plating) enhanced anti-corrosion technologies are also more and more attention.3.4 mold industry new techniques, new ideas and new models have been gradually recognizedIn the forming process, the main function of composite stamping die, superplastic forming, plastic precision molding technology, plastic mold gas-assisted injection technology and hot runner technology, high-pressure injection molding technology. On the other hand, with the continuous development of advanced manufacturing technology and raise the level of mold industry as a whole, in the mold industry, there are some new design, production, management ideas and models. Concrete are: to adapt to the characteristics of mold-piece production flexible manufacturing technologies; to create the best management and effective teamwork, lean production; to enhance rapid response capabilities of Concurrent Engineering, Virtual Manufacturing and global agile manufacturing, manufacturing of new production networks philosophy; extensive use of standard parts common parts of the division of work mode of production; meet the environmental requirements of sustainable development and green design and manufacturing.SummaryThe 21st century, in the new situation of economic globalization, with capital, technology and labor market re-integration of equipment manufacturing in China after joining the WTO will become the world's equipment manufacturing base. In the modern manufacturing industry, no matter which industry, engineering equipment, are increasingly used to provide the products from the mold industry. In order to meet the user's high-precision mold manufacturing, short delivery time, the urgent demand low-cost, mold industry is extensive application of modern advanced manufacturing technology to speed up the mold industry, technological progress, to meet the basic sectors of the mold process equipment urgent needs.模具的发展1模具在工业生产中的地位模具是大批量生产同形产品的工具,是工业生产的主要工艺装备。

Now, preparing pre-service teachers, I have a different perspective on their lives. Here are some truths I share with them.As a young teacher, I ** that loving to be with kids would be enough to get me through long days. I discovered early onthat teaching is a hardjob **.It'S so much more than helping kids and creating engaging assignments; it isconferences,***grading and paperwork.No one told me that annual class pictures would document my out-of-date clothes, unfashionable hairstyles, andfluctuating body mass. Luckily, in my younger years, I instead mindlessly tossed them in a ** drawer and let them accumulate over the years, I am so glad I did. Those embarrassing class pictures now make up the bulk of my "why I love teaching" emergency box. On a day when I need some reminding of why I keep plugging along, I pull those *** out and flip through the memories I made with them. Don' t get me wrong, there are some pictures that make me ask, "How did we ever survive?" But even those moments make me smile because we did survive and, in many cases,we thrived. They are a great reminder of how my work and passion have influenced those students'lives.You have to come to the classroom with a deep understanding of your role and how it extends.Early on in my career, I complained to a colleaguethat I was a classroom teacher, so why was I being asked to be a mom, nurse, custodian, therapist,social worker, cheer leader, and judge and jury? Mycolleague said,***are what the kids need you to be at that moment." At the time, her advice didn' t help,but I later realized how right she was. Students are people too, and justlike us grown-ups. Be empathetic and take care of your students' needs.That is the unwritten role of the teacher. I'm probably not the first or last teacher to strive for perfection in every ***** spent too much time in my younger days thinking that once I had more experience with the curriculum, once I had a different mix of students, and once I mastered classroom ****. I would be able to deliver flawless lessons. What I have come to realize is that the land of perfect lessons doesn' t exist. We are human beings who are tasked with working with other*****. That adds up to a whole lot of fallible human beings in one classroom. You' II never be able to predict how every student **** in every moment or how you will adjust to the hurdles you face each day. Be as gentle, patient, and *** with yourself as you are with your students.Those children in ** you are also the ***joy of their families. You've been given the privilege of educating them.Parents are not hiding the good ones at home and sending you the rambunctious ones for ****. Youare getting the best they' ve got. Spend time building relationships.You will want to quit and plan a new *** that has nothing to do with kid,****twice as much and provides the freedom to use the restroom on a whim. You' II**a time when you will sit down to eat lunch. ****..I hope you will spend some time thinking about your "bigger purpose." And with that *** of purpose, I hope that you will pause and remember what brought you to the profession in the first place.21. What has made the **** * understand those ***** roles ofa teacher?A.Her students' expectations.B.Her collague' S timely advice.C.Her sympathy with her students.D.Her awareness of student' s needs.[答案] D22. Why does the *** call her desk drawer an“emergency box” in Paragraph 4?A.Because it reminds her of her purpose of teaching when something unexpressed occurs.B.Because it wakes up her memory of how they have pulled themselves through hard times.C.Because it brings back her old and unfashionable image as a young teacher.D.Because it records all sacrifices she has made for her students over the years.[答案] A23. Which of the **** summarizes the *** idea of Paragraph 5? A.The notion of perfect lessons is not well grounded at all.B.Good classroom management is essential to flawless lessons.C.Kids are unaware of the mistakes their teachers make in class.D.Both teachers and students tend to make mistakes in classroom.[答案] A24. What does the author *** to share with pre-service teachers at****end of the****7A.Teachers are free to decide whether to quit or continue their jobs.B.Don' t easily give up your teaching career considering its significance.C.Don' t enter the workforce if you are not prepared with a bigger purpose.D.Teachers are able to find jobs that are less demanding yet more rewarding.[答案] B25. Which of the following******in meaning to.the underlined phrase "take a toll on "in the 1a*****.A.Be in charge ofB.Be dependent onC.Have an effect onD.Take advantage of[答案] C阅读理解,回答26-30题Passage 2As a species, **** *incredibly smart. We tell stories, create magnificent art and astounding technology,build cities, and explore space. We haven't been around nearly as long as many other species, but in many respects we' ve accomplished more than any *. We eat them and they don' t eat us. We even run scientific***on them--and are thinking about re-creating**** those that have gone extinct. But our intelligence comes with a curious caveat: our babies are among the dumbest-or,rather,the most helpless--that exist. A baby******an stand within an hour of birth, and can even***** flee predators on its frst day of life. A baby monkey can grasp its mother and hang on for protection and nourishment. **** infantcan' t even hold up its own head.The evolution of ***intelligence isn' t something that Celeste Kidd had ever pondered. A developmental cognitive scientist who currently works at the University of Rochester, her work had focussed mostly on learning and decision-making in children. Over years of ***oung children, she became impressed with the average child' s level of sophistication. But when she looked at the ****sh encountered, she saw a baffling **** ofhelplessness: How *** *they be so incompetent one second andso so soon ***** One day, she posed the question to her colleague Steven Piantadosi."Both of us wondered what could possibly justify the degreeof helplessness human infants ** she told me ****. "Evenother primate babies, like baby chimps, which are close in evolutionary terms, can cling onto their moms." She began to see a contradiction: ***are born quite helpless, far more so than any other primate, but, fairly early on, we start becoming quite smart, again far more so than any other primate. What if this weren' t *** so much as a causal pathway?That' s the argument that Kidd and ***make in their new paper, published in a June issue of PNAS.Humans become sointelligent because *** infantsare so incredibly helpless, they argue; the one necessitates the other. The theory is startling, but it isn't entirely new. *** have been pondering the peculiarities of our birth and its evolutionary significance for ***some ***. Humans *** to the subset of mammals,**** viviparous mammals, that give live birth to their young. This*** that infants must grow to a mature enough state inside the body to be born, but they can' t be so big that they are unable to come out. This leads to a trade-of: the more******an animal is, the larger its head generally is, but the birth canal imposes an upper limit o1n just how large that head can***it gets stuck. The brain, therefore,must keep maturing, and th*****continue growing,long after birth. *** intelligent an animal will eventually be, themor*****immature its brain is at birth.Researchers have long known **** * trade-off,***** the connection between brain size and neural density and intelligence. For instance, Robin **** found that the ratio of neocortical volume to brain size can predict the social-group size in a**** of species, **** bats, cetaceans, and primates,while Simon Reader has demonstrated links in tool use and innovation to brain size in primates. Kidd and * **** new idea is that increased helplessness******mandates increased **** in parents--and that a runawayselection dynamic can account for both. Natural selection favors humans with ******because those humans tend to be smarter. This may create evolutionary incentives forbabies**** born at an even earlier developmental stage,**** require more intelligence to ***.* This creates the dynamic: over time,helpless babies make parents more ****.which makes babies more helpless, which makes the***** intelligent, and so on.26.According to paragraph 1, *** of the following is true?A.Some species are smarter than human beings.B. Extinct species have been re-created by scientists.C.Babies of other species are smarter than human infants.D.Fewer species are earlier inhabitants than human beings. [答案] C27. What surprised* *** Kidd regarding children's *** maturation?A.Infants' helplessness when they are born.B.Children' S high intelligence when they grow up.C.Children' S leap from helplessness to sophistication.D.Children' S incompetence in learning and decision-making. [答案] C28. What can we *** form Paragraph 3 ** *brain development?A.Babies' helplessness at birth is an indication of human intelligenceB.Other mammal brains are more mature than human brain at birth.C.Only itelligent mammals give live birth to their babies.D.All animal brains are equally immature at their birth.[答案] A29. What is the main **** author intends toconvey?A.Newborns helplessness facilitates the development ofparent' s intelligence.B.The 1arger the brain of a species, the larger its social-group size.rge brain size contributes to better tool use and innovation.D.Human beings with large brains are not necessarily smarter. [答案] A30. Which of *** following title ***describes the passage?A.Why are babies so dumb if humans are so smart?B.Why do babies learn faster than other mammal babies?C.Why is human' S intelligence higher than that of other animals?D.Why is the development of human brains slower than that of other animals?[答案] A简答题针对相关问题作出简明扼要的回答。
