一旦能量不同，那么当然我们需要考虑，它们的波耳兹曼常数。

As soon as the energies are different, then of course we need to account for all those Boltzmann factors.

这意味着，配分函数，是带波耳兹曼常数的各项之和。

And what that means is, in the partition function, which is a sum over all these terms with these Boltzmann factors.

马克思·威尔指出光是种电磁波，其在真空中的传播速度是个常数c。

Maxwell showed that light was a vibration in the electromagnetic field, and that it travelled at a constant speed, c, in a vacuum.

So, first, if I point out when l equals 0, when we have an s orbital, what you see is that angular part of the wave function is equal to a constant.

首先，如果ｌ等于０,那就是ｓ轨道，你们可以看到,它波函数的角度部分是一个常数。

The more important thing that I want you to notice when you're looking at this wave equation for a 1 s h atom, is the fact that if you look at the angular component of the wave function, you'll notice that it's a constant.

我要你们注意的,更重要的一点是,当你们看到,这个氢原子1s轨道方程的时候，如果你们看,波函数，的角向部分，你们会发现它是一个常数。
