再来看看,不可逆热机的效率。
So now let's look at the efficiency of our irreversible engine.
让我们推广卡诺热机的结果。
也就是说,这个热机的效率,比卡诺热机低。
So in other words, this engine is running less efficiently than my Carnot engine.
So, what I want to do is make a new engine which really just consists of two engines, side by side.
我们先构造一个,由两个热机组成的热机,并排排列。
So, the total work that we can get out must be zero, out of the whole sum of them.
因此,我们可以从这两个热机,得到的总功,一定是零。
Now I want to just assume that in some way they're different.
现在我们假设,这两个热机在某些方面是不同的。
