You wanted to go from liquid to gas, you could actually go around this critical point, and never actually see a phase transition.

But now, it's not as a function of the composition at the liquid phase it's a function of the composition in the gas phase.
但是现在,这里不再是以液相的组分比,作为变量,而是以气相的组分比作为变量。
So if you take them all from the liquid and put them all up into the gas phase, it must be the same.
所以如果把全部的,都从液态变成气态,它一定是相等的。
However, if exposed to heated air, the phase change from liquid to gas is more intense, and produces an efficiency of 70 percent.
然而如果该过程中加入热空气,相变过程就会加剧,达到70%的效率。
And we squeeze, and now we've got more water in the liquid phase than in the gas phase.
我们继续压缩,现在液态的水,比气态的水更多。
So I've gotten the composition in the gas phase in terms of the composition in the liquid phase.
我利用液体中的组分,表示出了气体中的组分。
In the gas phase and the liquid phase.
在气相和液相都有。
We've found composition in the gas phase in terms of composition in the liquid phase.
我们已经用液相的组分,写出了气相的组分。
Ok. Then you started looking at both the gas and the liquid phase in the same diagram.
好,然后在同一张图中,考虑气相和液相。
There's the gas phase. There's the liquid phase.
这里是气相,这里是液相。
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。
