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.
我们来画相图，蒸汽压下降，意味着凝固点降低，和沸点降低。
It's going to come from the vapor pressure lowering not from the osmotic pressure, which we'll do next.
我们可以从蒸汽压得变化，而不是渗透压，得到这个结果。
There is vapor pressure lowering.
蒸汽压的下降。
And the first thing that you can use this for is to look at your first colligative property which is vapor pressure lowering.
你可以利用这个定律的第一个地方，是我们的第一个依数效应，在这个效应中蒸汽压下降。
Colligative properties are the properties like the vapor pressure, lowering when you have a mixture in a liquid, instead of having a pure substance you have amixture of substances here.
依数现象是这样一种现象，当你把物质混合在一起的时候，你不会得到纯物质，而是得到混合物质。
