And on this side, we're going to write out an engine, and we're going to say this is a Carnot engine.

在这边，我们画出一个热机，是卡诺热机。

So the first step to doing that is I want to just generalize our results so far for a Carnot cycle.

第一步,首先来推广一下,卡诺循环的结果。

So, the engine that I'm going to illustrate is called a Carnot engine.

这个热机,叫做卡诺热机。

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。

Now, if we go back to our Carnot cycle which is a set of reversible paths, it's useful to compare this to what happens in an irreversible case.

如果回到卡诺循环,它是由一系列可逆过程组成，我们将它,和不可逆过程的情况相比较。

And now we're going to specify, we're going to do a Carnot cycle for an ideal gas.

我们具体地指定一个卡诺循环，这是理想气体。

So in other words, this engine is running less efficiently than my Carnot engine.

也就是说，这个热机的效率,比卡诺热机低。

OK, so here is just an engine like what we've already seen, and I'm going to specify that this is a Carnot engine which is to say all the results that we just derived hold for this case.

这一个热机,跟我们以前见过的差不多，我们把它确定为,卡诺热机,所以我们之前得到的结果都对它适用。

So generalize our Carnot engine results.

让我们推广卡诺热机的结果。

And the cycle it's going to undertake is called a Carnot cycle, and it works the following way: we're going to do pressure volume work.

它的循环过程,叫做卡诺循环，过程如下：,这是个压强体积系统。

We're building up to entropy and to engines, Carnot cycles, etcetera.

我们要研究，熵，热机，卡洛循环等概念。
