lubricating layer meaning in Chinese

润滑层

Many experiments indicate that flocculus steel balls possessing reticulate veins surface tend to elastic fluid kinetic lubricating layer and improves of the lubricating conditions of bearings . the bearings become quite , and have long life . therefore , in this paper we bring forward a new method to process flocculus steel balls possessing reticulate veins surface
而且许多实验表明：表面呈现网状纹理形貌的“绒面”钢球，有利于钢球和套圈之间的点接触区域形成全膜弹流润滑层，使得轴承的润滑状态得到改善，从而实现轴承减振降噪和提高寿命的目的。
