Science and technology are the primary productive forces. We are all familiar with this saying. In fact, China's life has been turned upside down since it came out of hard times, and the most important one is the development of science and technology. As a matter of fact, with the mastery of technology, we have the right of discourse in the world and the priority right of development in industrial development. The most important thing is that the research and development of precision instruments, especially the development of detection and analysis instruments, has greatly shortened the development distance between China and Europe and the United States.

Xu kexin, a professor at tianjin university, member of the science and technology commission of the ministry of education and member of the international society of optical engineering, pointed out that advanced measurement technology and precision instruments are the tools of scientific discovery and the seed of technological innovation. Techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) allow us to detect disease earlier. Image sensor (CCD) has been a key component in mobile phones and digital cameras.

Social needs determine the development of testing instruments

The development of the real society also raises many new questions that must be answered and solved in science. How do industrial emissions affect climate change, the environment and even human health? The dioxins concentration is low, the measurement method is complex and can only be carried out off-line. However, the mechanism, evaluation and monitoring methods of trace substances on human health are more urgent scientific problems.

As the 80 s, our country made in urgent need of the national urban distribution of acid rain, at a time when economic conditions are decided the need to independent research and development of scientific research personnel, everything comes to him who waits, researchers are overcome the various difficulties in our country, through superior knowledge and exquisite technology, finally developed the first ion chromatograph, and immediately into a commercial, equipment all over the country cities test the composition and concentration of acid rain.

Again for events related to national security, such as our country involved in space technology and the development of nuclear weapons, the use of instrumentation must be domestic independent research and development, which is based on the habits of the Chinese people, of course, but also to the technical secrets, because once used foreign instrument to test the equipment, the data in the case of online communication, is easy to cause the loss of state secret technology.

Chen baoquan, director and editor of the China association for science and technology journalism, said that measurement and instrument technology also reflect national strength. According to data released by the national institute of standards and technology of the us department of commerce in the mid-1990s, the output value of instruments in the us accounts for about 4% of the gross national product, but it drives up to 66% of the related output value. A 2007 strategy report by the U.S. department of commerce's national institute of standards and technology pointed out that measurement technology is the key to improving manufacturing and people's quality of life in the 21st century, an area that is also essential to maintaining national competitiveness. In an effort to regain its edge in measuring and analytical instruments, Japan's ministry of education has launched a cutting-edge surveying venture that has cost tens of billions of yen.

High-end instruments still need to be imported

At present, China lags far behind the world powers in measuring technology and precision instruments, and the resulting technological innovation has a wide impact. Unless we develop a development strategy and catch up as soon as possible, the gap will continue to widen. Chen baoquan pointed out that China's science and technology investment has increased significantly, the purchase of large instruments and equipment has begun to take shape. But 60% of them are imported equipment, especially expensive high-end instruments and equipment are basically imported.
