我们继续压缩，现在液态的水，比气态的水更多。
So I'm going to find the total pressure as a function of the composition in the gas phase.
我想找到总压强作为，气相中组分的函数。
So what that means is, relative to the ideal solution, they'd rather go up into the gas phase.
那意味着，相对于理想溶液，它们更愿意上升进入气相。
Going to make the same diagram, except now I'm going to use the gas phase as my reference point.
然后就可以做出相图了，唯一不同的是我这里用气相作为我的参考点。
And I know that should tell me immediately whether the composition in the gas phase is here.
我已经知道液相的组分在这里，我知道液体的组分之后。
Because really what we want is the total pressure as a function of the composition in the gas phase.
因为我们想要的是，总压强作为气相组分的函数。
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。
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。
