【正文】 s economic and social development of the Tenth FiveYear Plan clearly to the development of instrumentation in an important position. National Program for the Development of Instruments referred to, but in an important position, is the first time since the founding of the PRC. Shortly thereafter, the State Planning Commission, Economic and Trade Commission, Ministry of Science and Technology and many other ministries are listed a number of special, a large amount of money spent to support the development of instrumentation. In 2005, the National Development and Reform Commission issued a formal to revitalize the equipment manufacturing industry to speed up a number of opinions, the various industries in the 16 selected areas of priority to the development of specific legislation to support the development of the first of which is the 11 major projects and sophisticated automation control system testing equipment. In 2006 to develop national longterm scientific and technological development program, involves a number of control and measurement instrumentation development projects. April 2008, Ministry of Science and Technology, National Development and Reform Commission, Ministry of Education and the China Association for Science and Technology have jointly issued the innovative ways to work on strengthening a number of opinions, officially launched the work of innovative ways to carry out in the country. This paper, we explicitly put forward innovative approaches, including creative thinking, innovative approaches and innovative tools for the three elements of the main innovative tools to promote scientific and technological innovation refers to the scientific instruments. The important role of scientific instruments have been further enhanced, more powerful research and development support. In addition, 863 plans, especially in the space program and other national science and technology development plans to support the control and measurement instrumentation has also been on the development of an important position. Is in a very favorable situation, in recent years, China39。s society the importance of the role of a clear description of the image that we are very familiar: the instrumentation of industrial production is the multiplier scientific research military bat effectiveness , as well as the activities of modern society, Judge materialized. The content and the amount of the note do not have any explanation, we are clear. It is encouraging to note, instrumentation and measurement control multiplier, bat effectiveness and physicochemical judge has an important role in the munity, including government departments by consensus, bee the instrument to accelerate the development of science and technology and industrial scientific basis, and in documents, reports and widely quoted speech. As a result of instrumentation and measurement control of the important status and role in society attach great importance to the country in recent years adopted a series of major measures to accelerate development. Worthy of special initiatives are: in March 2001 at the seventh session of the Fourth National People39。s information age, science and technology and promote the development of the national economy and how important status. In that case, control and measurement instrumentation on the promotion of science and technology, economic and social development in an important role in what? 2000 Instrument Society of China to accept the State Planning Commission, State Economic and Trade Commission and the Ministry of Science and Technology Commission, organized a study group of experts across the country carried out the instrumentation industry for a period of three months of investigation and research. Very rare is that Wang Daheng, Yang Jiachi, Jin Guofan to three academicians participated in the research activities and research after the end of the study group chaired two mittees to make a 1 on the revitalization of China39。s control of the significant progress in recent years.
