蒸汽压缩之后反应堆系统的压力就会降低。
The steam then condenses and reduces pressure in the reactor system.
结果意味着在水中放入溶质的效果，是降低了气态水的蒸汽压，很简单，这叫做蒸汽压定律。
That means that the act of putting some solute in my water decreases the vapor pressure of the water in the gas phase Pretty simple. It's called vapor pressure law.
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.
