The valence electron structures of some interphases with, A_2 and B_2 structureswere analyzed and their transformation points are calculated by Yu's EmpiricaI Electron The-ory.

本文应用经验电子理论对一些具有A＿2，B＿2型结构的电子化合物进行了价电子结构分析及相变点计算。

And the idea is that when you do these Lewis dot structures, we're representing electrons with dots, which we'll see in a minute, and each dot is going to represent a valence electron.

而当你遇到这些路易斯点结构时，我们会将电子用点来表示，我们马上就会看到，每个点都代表了一个价电子。

So, Lewis structures are really a model for a way to think about what the valence electron configuration is, and as I said, it's not based on quantum mechanics, it's something that Lewis observed far, far before quantum mechanics were discovered.

路易斯结构实际上是一个用来考虑价,电子排布的模型，而就像我说的，它并不以量子力学为基础，而是路易斯在以前发现的,在量子力学出现很早前。
