查询词典 friction

For thinner films, stacking faults are preferred in the scratch process, which increase storage capacity of plastic deformation in the film, and further inhibit the stick slip amplitude in the friction oscillation process. For thicker films, dislocation loops, which glide along slip plane downward to the grain boundary, dominate over the stacking faults, and finally dissipate on the grain boundaries. Since the intergrain stacking faults are inactive in thicker films, the stick slip phenomenon is similar to that in single crystal.

摩擦过程中易在较薄的薄膜表面和薄膜晶界之间产生穿晶层错，穿晶层错的产生增加了薄膜蓄积塑性变形的能力，从而抑制材料表面摩擦力在黏滑过程中的振荡幅度；在比较厚的薄膜中不易生成穿晶层错，在摩擦过程中位错环依次向体材料发射，并与晶界反应，湮灭于晶界，黏滑动摩擦响应与单晶相似。

This type of tubing anchor is constitute by anchor body,turnover slip and the centralizer,it is installed in the lower end of the PCP.When the rotor is rotating,it drives the shell and rotary anchor to rotate clockwise.In the role of the friction between turnover slip and the casing,the turnover slip turns over , its outer diameter increases,then it locks to the casing and the anchoring implements.
