And specifically, when we talk about ionization energy, it's assumed that what we mean is actually the first ionization energy.

特别地，当我们讨论电离能的时候，我们默认,这指的是第一电离能。

and I mean, it's just a... it's a crazy energy out here.

我是说，就是……就是有一种疯狂的能量。

I mean we can, we can sort of understand why OK, the total energy, if we measure it, we measure a process which is not reversible.

例如我们易于理解为什么，当试图测量一个不可逆系统的总能量，给出的或许。

And when we say lower in energy, of course, what we mean is more negative.

当然当我们说能量更低时，我们的意思是更为不活跃。

We've got a lot of constants in this solution to the hydrogen atom, and we know what most of these mean. But remember that this whole term in green here is what is going to be equal to that binding energy between the nucleus of a hydrogen atom and the electron.

在这个解中有很多常数,其中大部分我们,都知道它们代表的意思,但记住是这整个绿色的部分,等于核子和电子的结合能。

So that should mean that the energy that's transferred to the electron should be greater, but that's not what you saw at all, and what you saw is that if you kept the frequency constant there was absolutely no change in the kinetic energy of the electrons, no matter how high up you had the intensity of the light go.

所以这意味着转移到电子,上的能量也越大，但这并不是，我们观测到的现象,我们所看到的是,如果固定光的频率不变,不管光强如何变化,电子的动能没有任何变化。

So it does not mean that we have more energy per photon.

它不代表每一个光子,有更高的能量。

I mean, if the energy is lower to occupy a smaller volume, then if I have this room and a bunch of molecules of oxygen, and nitrogen and what have you in the air, and there are weak attractions between them, why don't they all just sort of glum together and find whatever volume they like.

我的意思是，如果占据小的体积会使能量降低，如果我有这样一个空间,和一些氧气，氮气和其他空气中有的气体，并且分子之间还有微弱的相互作用，为什么他们不黏在一起,然后占据他们所想要占据的体积。
