Average relative deviations between calculated values and experimental data of gas phase mole fraction were all less than 0.78%.
汽相摩尔分数的实验值和计算值的平均相对偏差均小于0.78%。
And for each component we have to describe its mole fraction in that particular phase.
对每一个组分我们都要知道，它在各个相中的摩尔分数。
You decrease the mole fraction of the less volatile material in the gas phase.
更不易挥发的物质，在气相中的，摩尔分数减小了。
So what's the mole fraction of B in the gas phase?
那么B在气相中的摩尔分数是多少？
And if we go over here, this is telling us about the mole fraction in the gas phase.
如果我们到达那，它告诉了我们气相的摩尔分数。
OK, so we're going to look at temperature and mole fraction phase diagrams.
好，让我们看看温度,和摩尔分数相图。
That means I could follow the same sort of procedure that I indicated before when we looked at the pressure mole fraction phase diagram.
这意味着我们可以用，之前压强摩尔分数，相图里类似的方法。
It's not easy to calculate a priori what it's going to do all the way across the phase diagram for any mole fraction.
对于任一摩尔分数，去预计它穿越相图，会做什么并不容易。
And the point is, now we're going to start, since the mole fraction in the gas phase that we're starting from is the same number as this was.
我们从这一点开始，因为气态的摩尔分数不变，我们从之前相同的数字开始。
So this is the one that's showing us the mole fraction in the liquid phase.
这是告诉我们,液相摩尔分数的曲线。
PROFESSOR: No. Because, so it's the mole fraction in the gas phase.
教授：不，因为这是气态中的摩尔分数。
PROFESSOR: No. Because, so it's the mole fraction in the gas phase.
