When the equivalent strain rate is relatively low, this influence can be neglected and the compression process can be considered as an isothermal process. While the equivalent strain rate is high, this influence is of importance and the compression process can be approximately considered as an adiabatic process.

当等效应变速率很小时，变形热效应对流动应力的影响可忽略不计，压缩过程可近似认为是等温过程；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。
