我得到了，气相和液相的，摩尔数的比的表达式。
And so that's the point, is that the ratio of moles in the gas and liquid phases is just given by the two segments of this on either side.
那就是问题的关键，是气相和液相中的，摩尔比，由这两边的，两部分给出。
Because of the large expansion ratio of liquid to gas with cryogenic liquids, it is very important to provide adequate ventilation where cryogenic liquids are stored and used.
因为液体到气体的大膨胀率，为正在使用液氧的地方提供充分的通风非常重要。
