One is called the S-N curve of surface fracture mode. It is governed by a crystalslip on the specimen surface, which occurs in the region of short fatigue life and high stress amplitude level.
一组叫做表面破坏模式的S-N曲线，它发生在高应力幅短寿命区，是由试样表面晶体滑移引起的。

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。

On this base, the open slip system of nickel base single crystal alloy at high temperature condition has been determined from test data.
