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。

As we expected, it's less than one, and of course if we build an engine, we want it to be as high as possible, as close to one as possible.

就像预先期待的一样，效率小于一，当然如果我们建造一台热机，我们希望效率越高越好，尽可能接近一。

So it's going to be the case for any irreversible engine.

这对所有不可逆热机都成立。
