We looked at pressure change before, actually, in discussing the third law, the fact that the entropy goes to zero as the absolute temperature goes to zero for a pure, perfect crystal.

在讨论热力学第三定律的时候，我们讨论过压强变化，即对于纯净的完美晶体，随着温度下降到绝对零度熵也变成零。

A third statement of the second law of thermodynamics makes use of a new concept called entropy.

热力学第二定律的第三种陈述方式引用了一个叫做熵的新概念。

youdao

It is shown that the existence of the residual entropy and the entropy-freezing are in fact equal and that the third law of thermodynamics is still valid in glass systems.

对零点剩余炳的存在提出了一种新解释，指出零点剩余熵的存在和熵冻结实际上是等价的，比热测量的结果并不违背热力学第三定律。
