好，然后在同一张图中，考虑气相和液相。
The chemical potential of a molecule of A in the liquid phase here is the same as the chemical potential of A in the gas phase. So we have two constraints.
液态分子A的化学势,等于气态分子A的化学势,所以我们有两个约束条件。
Chemical potentials of a, in the gas phase has to be the same as the chemical potential of a in the liquid phase.
处于气态的A的化学势等于，处于液态的A的化学势。
The function of the phase separator is to simply divide the liquid and gas and then vent the gas from the system.
分相器的功能只是简单的将液体和气体分开，然后从通风系统中排出气体。
And I can invert this to get the composition in the liquid phase in terms of the composition in the gas phase it's not so straightforward, but you can get xA as a function of yA, as well.
然后即可以用气体中的组分，写出液体中的组分，虽然过程不简单，但是你可以得到xA作为yA的函数。
Now if we look at Raoult's law, it's straightforward to say what is the chemical potential for each of the substances in the liquid and the gas phase. Of course, it has to be equal.
如果我看看拉乌尔定律，很直接地就知道，液体和气体中，每一种物质的化学势，当然，它们必须相等。
