1·The results showed that during drawing wire the cleavage crack of diamond in crystal face(111)is the main reason.

拉丝过程中金刚石模子的失效是由金刚石沿（111）面解理引起的。

2·Its explicitly explained how the cleavage step pattern is formed by the cleavage crack intersecting with screw dislocation.

本文对解理台阶的形成模型——解理裂纹与螺位错交割模型进行了诠释。

3·In low temperature cleavage physical model, it is of Paramount importance to ascertain the nature of the critical event in the formation of a cleavage crack.

在低温解理断裂的物理模型中，最重要的是确定解理裂纹形成中的临界事件。

4·Under the second critical load, the regions, where the three criteria are satisfied, are overlapped each other and cleavage crack is nucleated and propagates.
