Based on the experiment results of single crystals, a discrete slip model is established to describe the crystal plastic deformation.

基于韧性单晶体实验现象，建立了描述晶体塑性变形的离散滑移模型。

Based on these, the physical model of plastic degenerating layer has been established and the fractional mechanism of surface crystal particles has been explained by micro-edge cutting theory.

在此基础上，建立了陶瓷镜面磨削塑性变质层的物理模型，并用微刃切削理论解释了表面晶粒的碎化机理。
