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。
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。
And you know, you could have a reversible engine with lots and lots of steps, but you could always break them down into some sequence of adiabatic and isothermal steps.
你们知道,我们可以设计一个由,很多很多个,循环步骤的热机,但是总可以把它分割成,一系列的绝热,和等温过程。
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。
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。
