They want to get as far away from each other possible, the ideal angle is 120. But what we have here is a four-membered ring, so what angle does 90° that have to be, that bond? 90 degrees.

它们想要尽量远离彼此，最理想的是形成120°键角,但现在是个四元环,所以这键角应该多大？

BH3 All of our electrons are in our bonds, we want to got them a 120 degrees away from each other, that's as far away as we can get them.

比如说，它是这样的，所有的电子都在键中。

Now, in fact, that's as far as we can get with dominance arguments in this particular game, but nevertheless, let's just stick with it a second.

目前为止,这些就是我们通过,此博弈得到的全部与优势有关信息了,然而,我们来再深究一下

And that may generalize again and it keeps going until you either get back to Adam and Eve, I guess. I don't think they were born in the US as far as I know, or you find somebody who satisfies that definition or you find that none of your parents actually are in that category.

降低到我的父亲或者母亲,是不是天生的美国公民呢,这个问题可以继续向下分解,你甚至可以追溯到亚当和夏娃的时候,据我所知它们并不是出生在美国的,或者你要么找到一个符合定义的人,要么发现你的父母都不满足条件。

Everyone would do that, no one would ever hold some other portfolio ... because you can see that this line is the lowest-- it's far--you want to get to the left as far as possible.

所有人都会这么做，没人会选择其他的投资组合,因为你们可以看到这条线是最低的-,你希望他越靠左越好。

You can make an A in this class by writing your paper as far enough ahead of time that you can take it to a writing tutor and get the writing tutor to help you get the style better, and then turn that version in.

要得A，可以尽量提前完成论文,然后拿给写作指导,让他们帮助你修饰文辞，然后再交上来。

And since we have two bars that are together like this, once they're both loaded up with electrons there's going to be negative charges that repel, so the electrons will want to get as far away as possible, and they're on their slow way to doing that, to getting as far away from each other as possible.

因为我们有两个棒像这样在一起，一旦它们加载了电子,就会因为有负电荷而排斥，所以这些电子就会,互相离开的尽可能远，它们的这个过程很慢，离开的尽可能远。

So we end up with 3 s p 2 hybrid orbitals, so we can think about what would happen here in terms of bonding, and if we think about how to get our bonds as far away as possible from each other, what we're going to have is the trigonal planer situation.

因为现在sp2轨道有1/3的s特征，2/3的p特征，而不是3/4。,我们最后得到3个sp2杂化轨道，我们可以想象,成键时会发生什么，如果我们考虑。
