The boundary line between stability and instability is the dry adiabatic lapse rate line.
稳定的和不稳定的界限就是干的绝热垂直率线。

While the equivalent strain rate is high, this influence is of importance and the compression process can be approximately considered as an adiabatic process.
当等效应变速率较大时，变形热效应对流动应力的影响相当显著，压缩过程基本上成为绝热过程。

The reason for the sawtooth chips is that the adiabatic shear localization occurs in the primary deformation zones when thermal softening exceeds strain and strain rate hardening.
