它的循环过程，叫做卡诺循环，过程如下：，这是个压强体积系统。

And the cycle it's going to undertake is called a Carnot cycle, and it works the following way: we're going to do pressure volume work.

任何不可逆过程中，效率是小于的卡诺循环。

For any irreversible process, the efficiency is less than that of the Carnot cycle.

这就是说，卡诺循环是一个理想化的，因为没有真正的发动机过程是可逆的，所有真正的物理过程牵涉到一些熵的增加。

This means that the carnot cycle is an idealization since no real engine processes are reversible and all real physical processes involve some increase in entropy.

Now, if we go back to our Carnot cycle which is a set of reversible paths, it's useful to compare this to what happens in an irreversible case.

如果回到卡诺循环,它是由一系列可逆过程组成，我们将它,和不可逆过程的情况相比较。
