How should the hydraulic system enter the air?

New materials mainly include 3D printing materials, biomedical materials, superconducting materials, etc. Structural materials mainly use their strength, toughness, hardness, elasticity and other mechanical properties. Strategic emerging industries represent the direction of a new round of scientific and technological revolution and industrial reform, and are the key areas for fostering new drivers of development and gaining new competitive advantages in the future. At the same time, the new material industry, which is also integrated with the advanced achievements of many contemporary disciplines, is the basic industry supporting the development of the national economy and the material basis for the development of other high-tech industries.

At present, three new material industry clusters have been formed in China, namely Bohai Rim, Yangtze River Delta and Pearl River Delta, and the regional clustering trend is becoming prominent. The domestic new material industry is still in a period of rapid development, and the industrial scale is expected to grow from 4 trillion yuan in 2018 to 8 trillion yuan in 2025.
