I've got two states here, three states here, two here, I need four, and if I can come up with these bonds, four, by the Hund rule I'd fill them like this.

我们已经有2个状态在这里，3个在这里，2个在这里，我需要4个，如果我能想到这些键，四个，通过洪特规则，我们就能像这样排布。

- But there's one potential gotcha here -- and this is where you have to be kind -- of piecing together the little clues along the way -- what have I done that's interesting here that had I not, I would have had a mathematical error?

但是这里有一个可能性-,这就是你需要把,一些线索拼凑在一起-,我这里所做的是很有趣的，如果我不这样做，我可能已经犯了个数学错误？

It says they're not the same, and boy, I need help on this one, John, John pre-defined eq in there.

我并没有对它进行定义,它说它们并不相等，噢同学们，在这里我需要帮助了，在这里并没有，it’s，not，，there’s，no,提前定义的等于啊。

So that's why we have this zero point here, and just to point out again and again and again, it's not a radial node, it's just a point where we're starting our graph, because we're multiplying it by r equals zero.

这就是为什么在这里有个零点，我需要再三强调，这不是径向零点，他只是我们画图的起始处，因为我们用ｒ等于０乘以它。

Another way of saying it is, anything that uses get float doesn't care what the details are inside or shouldn't, and if I change that definition, I don't have to change anything elsewhere in my code, whereas if I just have the raw code in there, I have to go off and do it.

换种说法就是，任何用到获取,输入这个功能的人不用担心具体的实现细节,如果我改变了这里的实现，我并不需要去改变我的代码,因为我的最底处的源码就在这里,我去改这里就可以了。
