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 adiabatic compression.

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.

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。

You've just done an adiabatic compression of the ideal gas, you can pretend there is an ideal gas.

这就是对理想气体的,绝热压缩，---我们把空气近似作为理想气体处理。

So if you've got to pump that tire really a lot, then you're going to you're going to really feel a lot of heat there. The compression of the basically it's an adiabatic compression.

所以若果你给轮胎，打了很多的气，你会觉得你感觉,阀门那儿非常的烫，这种压缩,基本上是一个绝热的压缩。
