1 英文文献翻译1.1 英文文献原文题目Progress and Prospect of research on Mechanical Engineering in ChinaIn twenty-first Century, human society faced four major problems: climate warming, resource depletion, population growth and environmental degradation. As time goes on, these problems will become more and more serious and insurmountable. People will find that ecology (the protection of the earth and the environment of human existence) may be more important than the economy. China will be the largest energy consuming country in the world. 20 years later, due to the depletion of oil and coal, the proportion of nuclear energy, solar energy, geothermal energy, wind energy and hydraulic energy will increase significantly. Manufacturing in the future is still one of the main means to create wealth of human civilization and promote human progress. The manufacturing industry is a pillar industry of the national economy, and it supports the other industries to promote ecological construction and economic growth. Faced with the above major problems, the manufacturing industry and its science and technology are facing severe challenges. Because China will realize the strategic transformation from manufacturing country to manufacturing power, to achieve this strategic transfer, the key lies in the innovation of manufacturing technology and its products. The competition between manufacturing industries is, in the final analysis, the competition of science and technology. Product innovation and independent brand building are important challenges for Chinas manufacturing industry.If we can correctly recognize, predict and face these challenges, take the strategy and strategy in time, and strengthen the original innovation and independent innovation of manufacturing technology and its products, China will become a powerful manufacturing country. Chinas high-end brand products will keep pace with the United States and Japan, and Chinas manufacturing industry will stand in the forest of the world.This article is the core of the comprehensive report of the 20082009 mechanical engineering discipline (mechanical manufacturing) development report compiled by the China Association for science and technology. This paper tries to make a review of the main new views, new theories, new methods and new technologies and achievements in the field of mechanical engineering in recent years. By using Delphy investigation and research analysis, the future of the development of the subject was predicted scientifically, and the development trend of the mechanical engineering discipline in the next 510 years and even longer period was prospected, and the priority areas and important scientific and technological problems in the future development of the discipline of mechanical engineering in China were put forward. Due to the limitations of time, information and knowledge, the omission and errors in this article are welcome.The definition and scope of mechanical engineering discipline is the science of the theory, method and technology of the performance, design and manufacture of mechanical systems and products, including two fields of mechanics and manufacturing science.Mechanics is a science that studies the mechanical structure and system performance and its design theory and method, including the mechanism, transmission, dynamics, strength, tribology, design, bionics, micro mechanics and interface mechanics involved in the manufacturing process and the mechanical system.Manufacturing science is the science of manufacturing processes and systems.
