If you want the chemical potential.
如果你想知道化学势。
That's just the chemical potential.
这是化学势。
乘以化学势。
Because the chemical potential is lower inside.

Now, what do we know about the chemical potential in both parts?
我们现在怎么知道，这两边的化学势？
Now, the chemical potential, as we saw, was the Gibbs free energy.
现在，化学势，就像我们看到的，等于吉布斯自由能。
So that's a very simple expression for the chemical potential of a.
那是A的化学势的，一个十分简单的表达式。
So it's going to be the chemical potential of the pure material.
所以他的化学势，等于纯物质的化学势。
The model is used to calculate the chemical potential of water.

And that's going to change what the chemical potential of a species is.
这回改变，物质的化学势。
The chemical potential has to be equal outside and inside the container.
容器内外的化学势,必须相等。
We know a lot about the chemical potential of something in the gas phase.
我们对于气相中的一些成分的，化学势了解很多。
So if we work out the chemical potential, it's just one over N times A.
如果我们计算出化学势，它就是N分之一乘以A
Right, it's just a number of moles times the chemical potential in each case.
对的，它只是摩尔数，乘以每种情况的化学势。
But as the pressure rises, now the chemical potential changes and goes up.
但是当压强升高的时候，化学式也会改变，上升。
That it's equal to the chemical potential RTlogp at one bar for an ideal gas plus RT log p.
等于对于理想气体一巴时的,化学势加上。
And so the chemical potential of the water is strongly affected by all the other constituents.
水的化学势受到，其他成分的强烈影响。
Well, that's just the chemical potential of a, in the pure state, at temperature t and pressure pT.
好，这就是A的化学势，在纯态，温度为T，压强为p总时。
So mu, the chemical potential for these configurations, dA/dN is just dA/dN. With T and V constant.
那么μ，构型的化学势，就是。
In other words, the difference in the chemical potential is, this changes as a function of pressure.
换句话说，化学势之差等于，这个差值随着压强的变化。
These log partial pressures all come from expanding out the chemical potential as mu naught plus RT log p.
这些log的分压都来自于,化学势对μ零加RTlogp的展开。
By the way, it's convenient because it looks just like the chemical potential in a mixture of ideal gases.
顺便说一下，它很简便，因为它看起来就像理想气体，混合物中化学势的表达式。
Chemical potentials of a, in the gas phase has to be the same as the chemical potential of a in the liquid phase.
处于气态的A的化学势等于，处于液态的A的化学势。
Since the gas and liquid are in equilibrium, therefore we know the chemical potential in the liquid phase too.
由于气相和液相的化学势相等，因此我们也就知道了,液相中的化学势。
The chemical potential of baryon is larger than that of strangeness, and they all go to zero at low side of values.
重子化学势比奇异子化学势大，在低端它们都一致趋于零。
Because it's in equilibrium, the chemical potential of that particular component has to be the same in all the phases.
因为它处于平衡状态，所以这个特定组分在所有相中的化学势，都必须相等。
The chemical potential from the fundamental equation up here is the derivative of a with respect to the number of particles.
化学势，从基本方程上说，就是A对N的偏导，因此对A取N偏导，因此化学势也能，用正则配分函数表示。
We learned that the pressure dependence of the Gibbs free energy gives you the pressure dependence for the chemical potential.
我们还知道吉布斯自由能，对压强的依赖关系决定了，化学势对压强的依赖关系。
So of course, the free energy in either case is just the sum of the number of moles of each times the chemical potential of each.
那么当然，任一种情况的自由能，就是各组分的分子数，乘以化学势再加和。
Now what I'd like to do is go a little bit further and just look at expressions for the chemical potential and the free energies.
现在我想，更进一步，看看化学势，和自由能的表达式。
