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。

By the way, it's convenient because it looks just like the chemical potential in a mixture of ideal gases.

在这种完全基于技能与个性的价值体系指导下，我们视运动员、音乐家或有权有势的商界主管为偶像。

With a value system based solely on skill and personality, we find heroes in athletes, musicians and in powerful business executives.

那么我们就得到了一个式子，用它可以来比较混合态的化学势，和相同条件下，纯态时的化学势。

And then we'll have an equation that will compare the chemical potential of the mixture under the same conditions as the chemical potential of a in the pure state.

But because in many cases we can reasonably either model or measure equations of state, collect data for a material for its temperature, pressure, volume relations, then in fact if we can relate all these quantities to those then in fact we really can calculate essentially all of the thermodynamics. For the material.

但是因为在很多情况下,我们能够合理的给出状态方程的模型,或者通过收集一个物质的，温度，压强和体积之间的关系,来测量其状态方程，所以实际上我们可以给出压强等物理量,和热力学势之间的关系,并计算出所有的热力学势，对于给定的物质。
