Since the 18th CPC National Congress, the average

According to statistics, by the end of 2017, the total amount of large-scale scientific research instruments and equipment with an original value of more than 500000 yuan in China's universities and scientific research institutions is expected to be nearly 100000 sets, and the total original value is expected to exceed 140 billion yuan, both of which are more than twice as large as before. 4. The transmission part of the equipment adopts the arc tooth synchronous transmission mode

after measuring its output voltage, the relevant person in charge of the national science and technology infrastructure platform center said in a science and technology interview on the 11th that since the 18th CPC National Congress, the CPC Central Committee and the State Council have attached great importance to the construction of scientific and technological innovation capacity, and China has made significant progress in the construction of scientific and technological infrastructure resources such as scientific research facilities and instruments, scientific data and information, biological germplasm and experimental materials. The survey and statistics of basic scientific and technological resources show that since the 18th CPC National Congress, China's scientific research instruments and equipment have increased at an average annual rate of 16%

as a part of the "climate change action plan" launched by President Obama last year, it is reported that since the introduction of the "opinions on the opening of national major scientific research infrastructure and large scientific research instruments to the society", 28 provincial-level local governments have issued 93 policy documents on the opening and sharing of scientific and technological resources, and more than 1560 universities and scientific research institutions have formulated more than 1900 open systems, covering all links of resource opening management. At present, the management of China's science and technology infrastructure resources has initially formed a system framework of "taking resource investigation as the guide, resource sharing service platform as the focus, informatization and standardization network service system as the main body, and innovative and diversified capital investment as the guarantee"

with the completion of the 500 meter aperture spherical radio telescope (fast) and China's stray neutron source projects, China has a number of major scientific research infrastructures that have reached the international advanced level, and the material foundation of scientific and technological innovation has been continuously consolidated. According to statistics, by the end of 2017, the total amount of large-scale scientific research instruments and equipment with an original value of more than 500000 yuan for the tensile test of steel arc welding head in Chinese universities and scientific research institutions is expected to be nearly 100000 sets, and the total original value is expected to exceed 140 billion yuan, both more than twice that before the 18th CPC National Congress. The number of scientific data, biological germplasm and other resources has increased significantly. In the digital citation index database released by Thomson Reuters, China's scientific data resources have an average annual growth rate of 37.5%, ranking first in the world; The total conservation of Crop Germplasm Resources in China accounts for 17% of the world, ranking second in the world
