All right, so you can't get perfect efficiency, 0 but at least if you were able to go to zero degrees Kelvin, then you'd be all set.

好吧，你得不到完美的效率，但至少如果能把温度降到,那你就万事俱备了。

As we expected, it's less than one, and of course if we build an engine, we want it to be as high as possible, as close to one as possible.

就像预先期待的一样，效率小于一，当然如果我们建造一台热机，我们希望效率越高越好，尽可能接近一。
