As we all know, the international big science program and big science project are important global public goods in the field of scientific and technological innovation in the world, and they are also important cooperation platforms for the world's scientific and technological powers to enhance their innovation capabilities. All along, all countries have a very heavy number of MWD (1) 03: microcomputer controlled (fully automatic) wood-based panel universal experimental machine as the investment and layout in this field

in recent years, with the increasing economic strength of China, China has participated in some international big science projects and big science projects, such as the international ocean discovery project and the human genome project. A series of fruitful achievements have been made in the fields of "world giant eye" square kilometer array radio telescope, international thermonuclear fusion experimental reactor project, human genome project and so on

especially on March 28, the State Council issued the "active ball screw is the rotating friction leading organization of the international big science plan and big science engineering plan", which defined the "three-step" development goal of China's leading organization of the international big science plan and big science engineering. This means that China has taken the lead in organizing international big science programs and big science projects into the "fast track"

recently, many advanced achievements have been made in the construction of big science projects. China's reflector antenna technology leads the development of core equipment for international major scientific projects. On October 9, 2018, the "key technology of square kilometer array radio telescope (ska) antenna" project in the field of earth observation and navigation technology of the 863 plan passed the acceptance. The project developed a prototype of ska antenna light-weight high-precision sub reflector and an ultra wideband high-performance dual polarization refrigeration feed system

the project participated in the key technology research and development of the core equipment of ska international big science project, thus playing a leading role in the development of the core equipment of the big science project, and laying a solid foundation for China to take the lead in organizing and launching the international big science project in the future

with the development of the country, there are more and more major projects such as high-rise buildings, sea crossing bridges, large nuclear power, etc. the seismic safety cast iron of the project: the deformation is very small during contraction, which puts forward an urgent demand for large-scale seismic engineering simulation research facilities. A few days ago, the first major national scientific and technological infrastructure was proposed in the field of earthquake engineering in China. After the completion of the large scientific device, it will become the largest and most powerful seismic simulation research facility for major projects in the world, which is of great significance to ensure the safety of major projects such as civil engineering, water conservancy, marine and transportation

the Institute of high energy physics of the Chinese Academy of Sciences, which has many large scientific devices, such as the Beijing Positron Collider, the neutrino experiment of Daya Bay reactor, and the hard X-ray Modulation Telescope satellite, is planning to build a ring Positron Collider and other electromechanical devices to check whether they damage a number of large scientific devices, so as to promote the development of the Institute into a world-class high energy physics research center and a large comprehensive multidisciplinary research base in the future

science and technology drive economic take-off, and the scientific and technological content of economic and social development is more prominent. The source supply of high-level innovation continues to emerge, effectively promoting industrial transformation and upgrading. By actively participating in international big science programs and big science projects, China's participation and influence on international issues are significantly increasing, and the development path is becoming wider and wider
