But what really happens is as you go on in chemistry, you draw so many of these you can just draw them without following the rules.

但是随着你在化学上的深入，你会画很多路易斯结构,以至于你可以不用管这些规则就能直接画出来。

And that's somewhat inconvenient because we're working with wave functions, but it's a reality that comes out of quantum mechanics often, which is that we're describing a world that is so much different from the world that we observe on a day-to-day basis, that we're not always going to be able to make those one-to-one analogies.

这对于研究氢原子，很不方便,但这就是事实,而且在量子力学中经常会出现这种事实,那就是我们要描述的世界，和我们日常所看到的世界,之间的差别是如此之大,以至于我们不能，做出一一对应的类比,但幸运的是我们不用管。

That's it. Again, these other p dxy dyz - or the d x y, d y z, those are going to be those more complicated linear combinations, you don't need to worry about them.

同样，这些p轨道,或者，它们是一些,很复杂的线性组合，你们，不用管它。

It doesn't actually have an electron in it, so we don't have to worry about whether it's very high in energy or not, we don't care that it's high in energy.

你也许会想，为什么我们不杂化这个2py轨道,它里面没有电子，所以我们不用管它的能量。
