Our constraint is going to be an adiabatic expansion or compression.
现在约束改成了,绝热膨胀，或者压缩。

And now we're going to have another adiabatic step, an adiabaticcompression.
现在我们进行另外一步，绝热收缩过程。

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