配分函数是什么,这些构型的？
so what's our molecular partition function for this configurational degree of freedom?
那么μ，构型的化学势，就是。

我们看到处理有简单模型，不同构型的聚合物的。
That is we looked at what would be a simple model for a polymer with different configurations available to it.
再考虑整个系统，它也可以分解成，平动和构型部分。

首先我们知道了电子构型，我们可以从，能量最低处开始填。
First we can do that by knowing the electron configuration, we can write it out just by going up the table here, up the energy levels.
换句话说，它表示构型能量是零，因为所有分子都冻结在基态。
So in other words, what it's saying is the configurational energy is zero, because everything is stuck in the ground state.
