在等温恒应变速率压缩过程中，随着等效应变速率的增大，变形热效应对流动应力的影响程度增大。

During the isothermal constant strain rate compression process, the effect of deformation heating on flow stress increases with increasing equivalent strain rate.

压缩气体基本上是等温的，即压缩气体过程温度变化很小。

Compressed gas is isothermal, that is, the process of compressed gases very small temperature changes.
