在19世纪,卡诺(Carnot)曾经提出了一个理想的热机模型:卡诺热机(Carnot engine),这个热机是在时间上可逆运作的,克劳修斯发现,可以定义一个物理量叫做熵: dS=dQ/T

carnot heat engine 卡诺热机 ; 卡诺循环
irreversible carnot engine 不可逆卡诺热机
a carnot engine 卡诺热机
inverse carnot engine 逆卡诺循环
irreversible carnot heat engine 不可逆卡诺热机
So generalize our Carnot engine results.
让我们推广卡诺热机的结果。
So, the engine that I'm going to illustrate is called a Carnot engine.
这个热机,叫做卡诺热机。
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。
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 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。
