We looked at the wave functions, we know the other part of solving the Schrodinger equation is to solve for the binding energy of electrons to the nucleus, so let's take a look at those.
我们看过波函数，我们知道解,薛定谔方程的其他部分,就是解对于原子核的电子结合能，所以我们来看一看。

and you can get it all mixed up in one, it's called the Neapolitan shake.
也可以都混在一起，叫拿波利奶昔。
-
We talked about the wave function for a 2 s orbital, and also for a 3 s orbital.
我们讲过２ｓ轨道的波函数，也讲过３ｓ轨道。
-
sigma1s And what we end up for our molecular wave function is sigma 1 s.
最后我们得到了分子波函数。
-
An electron is a particle, but an electron's also a wave.
电子是粒子，但是电子也是波。
-
So, that's having to do with the actual wave function.
正的波函数有关,以后它会更加有关系。
-
It makes sense to draw the wave function as a circle, because we do know that 1 s orbitals are spherically symmetric.
把波函数画成一个圆是有道理的，因为我们知道1s轨道是球对称的。
-
So, we can say that a circle is a good approximation for a 1 s wave function.
所以我们说一个圆是,对1s波函数的好的近似。
-
So, we can do that by using this equation, which is for s orbitals is going to be equal to dr 4 pi r squared times the wave function squared, d r.
用这个方程,对于s轨道，径向概率分布,4πr的平方,乘以波函数的平方,这很容易理解。
-
So to talk about it's squared, we're going to say it's sigma 1 s squared.
要讨论它的波函数，我们说它是sigma1s的平方。
-
More interesting is to look at the 2 s wave function.
看2s轨道波函数,更加有趣。
