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？
It's the molar fraction of B in the gas phase times the total pressure.
这分压等于气相中b的摩尔分数，乘以总压强。
B so it's got some mole fraction of B.
其中有一些摩尔分数的。
So that's our mole fraction of B.
这就是B的摩尔分数。
B We're going to have a molar fraction in the liquid phase for a and B.
考虑A和，在液态以一定的摩尔分数混合。
The cow-milk found in populations with a low incidence of type 1 diabetes has a much lower fraction of A1 and B betacaseins (instead they have the A2 variant).
1型糖尿病发病率低的人所食用的牛奶含酪蛋白（是A2形式的β酪蛋白，而含A1和B变种形式的β酪蛋白比例要低得多）。
