再来看看,不可逆热机的效率。

So now let's look at the efficiency of our irreversible engine.

一个是我们已经学过的卡诺热机， 另一个是任何一个其它可逆热机。

One is our Carnot engine as we've seen it, and the other is just any other reversible engine.

在证明卡诺定理时，不可逆热机只能作正向循环，不能令其作逆向循环。

While proving Carnot theorem, the irreversible heat engine can only run on forward circulation, but not on the opposite.

So what this says is the efficiency of any reversible engine T1 has to be one minus T2 over T1.

这就是说,任何可逆热机的效率都是,负T2除以。
