为了接近卡诺效率，所涉及的过程，在热机循环必须可逆且涉及没有改变熵。

In order to approach the carnot efficiency the processes involved in the heat engine cycle must be reversible and involve no change in entropy.

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.

任何不可逆过程中，效率是小于的卡诺循环。

For any irreversible process, the efficiency is less than that of the Carnot cycle.
