The point at which the solid and the liquid are in equilibrium is called the freezing point.

固体和液体的平衡点叫做冰点。

《牛津词典》

But again, if you know all the energies of the possible states, in the solid, in the liquid and the gas, statistical mechanics shows us that we can calculate the equilibrium between those.

但是，如果我们知道，物质在固相，液相和气相中所有可能态的能量，统计力学告诉我们，我们可以计算这些相的平衡问题。
