我们来画相图，蒸汽压下降，意味着凝固点降低，和沸点降低。

And we also drew a phase diagram to show how this vapor pressure lowering was going to imply freezing point depression and boiling point depression.

这就表示溶液上的，蒸汽压下降，所以这就是刚才说的饱和蒸汽压下降。

So, that means that the vapor pressure above the solution is lowered. So I should have said vapor pressure lowering.
