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。
One is our Carnot engine as we've seen it, and the other is just any other reversible 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。
So now let's look at the efficiency of our irreversible engine.
再来看看,不可逆热机的效率。
So this is some other engine that runs using reversible processes.
这是另一台,利用可逆过程工作的热机。
Let's just take our reversible engine and modify it a little bit.
我们就拿可逆热机为研究对象,并对它进行一点修改。
In a real engine, of course, you can approach the reversible limit.
在一个真实的热机里,当然,你可以达到可逆极限。
So it's going to be the case for any irreversible engine.
这对所有不可逆热机都成立。
