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。

The defects include cracks, color center, inclusions, step-faceting, low-angle boundaries and dislocation pile-up group.

这些缺陷包括：包裹物，色心，开裂，台阶面，位错，小角晶界和位错塞积群。

It is showed that twin dislocation is the activated step of the migration of twin-plane boundary during recrystallization.

指出，孪晶位错是再结晶过程中，孪晶界面迁移的激活台阶。

His conclusion is unambiguous: though reducing carbon-dioxide emissions will not end all human influence on climate, it is a necessary step towards reducing the risk of severe dislocation.
