接触理论是研究固体面的基础，其核心是建立载荷与真实接触面法向位移之间的

The contact theory is the basis for studying solid surfaces, and its core is to establish the relationship between the load and the normal displacement of the real contact surface. The contact model between solid surfaces generally starts from the contact model between ideal smooth surfaces. Through the special design and processing of the geometric structure and material organization of the surface at the micrometer and micronanoscale, a surface with special singular functions or performance can be obtained.
