双语例句
- 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？ - And the point here is that unlike this case, where you have a linear relationship, the relationship between the pressure and the liquid mole fraction isn't linear.
关键点在于与这个情况不同，这里我们有的是一个线性的关系，压强和液相摩尔分数的关系不是线性的，我们仍然可以把它画出来。 - Well it's the mole fraction of A in the gas.
这是气体中A的摩尔分数。 - And in terms of the molar fractions, it's the total pressure squared, times the mole fraction of NO2 squared, divided by the total pressure to the first power.
写成摩尔分数的函数，总压强的平方，乘以NO2摩尔分数的平方，除以总压强。 - So this xB, which is the liquid mole fraction, is now yB, the gas mole fraction.
所以xB，液态时的摩尔分数，现在是yB，气态摩尔分数。 - That the vapor pressure of the solute is related to the mole fraction in the solution.
溶质的蒸汽压，和溶液中溶质的摩尔分数成正比。 - So this is the one that's showing us the mole fraction in the liquid phase.
这是告诉我们，液相摩尔分数的曲线。 - And then you have one non-linear relationship there for the mole fraction of the gas.
然后你们会遇到气体摩尔分数，是非线性关系的情况。 - The pressures over the pure liquid A and B at the limits of mole fraction of B being zero and one.
纯液相A和B的压强，在B的摩尔分数为零和一的极限时的值。 - So, here is the liquid mole fraction at temperature two.
好，这是二点温度下的液态摩尔分数。 - Very small mole fraction.
摩尔分数很小。 - For a given media, and at a constant total pressure and temperature, the partial pressure of oxygen is proportional to oxygen mole fraction.
对一个给定的媒介，在恒定的总压和温度下，局部压力与氧的克分子数成比例。 - The gas mole fraction.
气体摩尔分数。 - And if we go over here, this is telling us about the mole fraction in the gas phase.
如果我们到达那，它告诉了我们气相的摩尔分数。 - And for each component we have to describe its mole fraction in that particular phase.
对每一个组分我们都要知道，它在各个相中的摩尔分数。 - OK, so we're going to look at temperature and mole fraction phase diagrams.
好，让我们看看温度，和摩尔分数相图。 - If we plot this versus xB, this is mole fraction of B in the liquid going from zero to one.
如果我们把它化成xB的函数，这是液相B的摩尔分数，从零到一。 - So, for each phase alpha, we have to describe its mole fraction.
对每个相α，我们需要它的摩尔分数去描述。 - Which is the form of the equilibrium constant not in terms of the partial pressures, but in terms of the mole fraction.
它不是与分压有关的，平衡常数，而是与摩尔分数有关。 - You decrease the mole fraction of the less volatile material in the gas phase.
更不易挥发的物质，在气相中的，摩尔分数减小了。 - And you'll have some different mole fraction than you started with before.
你会和之前开始的时候，有不同的摩尔分数。 - So that means just reading off it, this is xB, that's the liquid mole fraction.
直接读出来，可得是xB，是液相摩尔分数。 - B So it's got some mole fraction of B.
其中有一些摩尔分数的。 - And let's say the mole fraction of A in each of the liquid and gas phases, right?
我们在液相和，气相中都有A的摩尔分数，对吗？ - So that the vapor pressure of CS2 is related to the mole fraction of CS2 times the vapor pressure of CS2 if it was pure.
所以CS2的蒸汽压2，与CS2的摩尔分数2，和纯的CS2溶液蒸汽压的积成正比。 - Now, of course, since this is a mole fraction, it's always between zero and one.
现在，当然，由于这是摩尔分数，它总是处于零到一之间。 - The constraint is that the sum of all the mole factions has to be equal to one That's what it is, to be a mole fraction.
约束条件是，所有摩尔分数之和等于1。，这就是摩尔分数的意义。 - So that's our mole fraction of B.
这就是B的摩尔分数。 - And then I have a non-linear relationship between the pressure and the mole fraction in the gas phase.
然后我有压强，和气相摩尔分数之间的非线性关系。 - So this is the mole fraction of the liquid.
这是液相的摩尔分数。
