And we had the similar statement by Kelvin about the heat engine that required that some heat gets dumped into a cold reservoir in the process of converting the heat from the hot reservoir into work.

相同的陈述,同样的有开尔文表述：,把热量完全从高温热源,转移至低温热源的过程中,必然有功的输出。

The whole thing is being powered by sending heat from the hot to the cold reservoir.

所要做的所有事情,就是把热量从高温热源输送到低温热源。

You know the heat isn't going to flow from a cold body to a hot body without putting some work in to make that happen.

大家知道热量不会自发地,从冷的物理流动到热的物理,除非对它做功。

You couldn't just run something successfully in a cycle and get work out of it, using the heat from the hot reservoir, without also converting some of the heat that came in to heat that would flow into a cold reservoir.

如果一样东西在循环工作过程中,只有热从高温热源中流出，而没有热流入低温热源，那么此过程,不可能对外做功,不可能把所有热。

the zeroth law, which is the common-sense law, which says that if you take a hot object next to a cold object, heat will flow from the hot to the cold in a way that is well defined, and it allows you to define temperature.

上节课我们讨论了，热力学第零定律,这一定律源自常识：如果把一个热的物体,与一个冷的物体挨在一起，热量就会以确定的方式。
