They're pretty straight forward to do and it gives us an idea what kind of nodal structure we can expect it an orbital.

这个对我们来说很明显,而且让我们对,预计是哪类节点有个概念。

But what I'm going to tell you already is this is a case where, in fact, it's an exception to the idea that the lowest energy structure has the lowest ionization energy in the middle, and we can figure this out when we look at formal charge.

但是我已经告诉大家这个例子，实际上，是中心原子电离能最低的结构,的能量最低这一思路的一个例外，我们可以通过形式电荷看出这一点。

And so, here was his idea of the structure of matter.

所以，这是他对物质的结构的理解。

Well, now maybe the important thing is to allow Brooks to comment on that so that you can see how he makes use of Freud's idea and move us a little bit closer to the application of these ideas to the structure of a literary plot or of a fictional plot.

现在最重要的事是允许布鲁克斯对此加以评论,这样一来你们就能看到他是怎样运用弗洛伊德的观点,并且进一步将其运用于,文学情节或小说情节的结构中去。

The idea of a forward rate is that, implicit in that term structure is also a quote for the one-year rate, one year hence, because if you look at the two-year rate, can't you infer back what interest rates are going to be in one year?

远期利率隐含在期限结构中的,一年期利率报价,起息日是第二年初,因为如果你知道了两年即期利率,就可以很自然地推出一年即期利率

And resonance is the idea that sometimes one single Lewis structure does not adequately describe the electron configuration around a given molecule, so instead you need to draw two different Lewis structures to describe that more appropriately.

而所谓共振态,就是有时候一个路易斯结构不足以,完整描述一个给定分子的电子排布，因此这时你需要同时画出两个,不同的路易斯结构来描述它,这样会更恰当。

So remember, that when we talked about Lewis structure, the organizing principle behind Lewis structures is the idea that within the molecule the atoms are going to arrange their valence electrons, such that each atom within the molecule has a complete octet or full outer shell.

记得，当我们讨论路易斯结构的时候，路易斯结构所遵循的组织原则是这样一种思路,那就是分子中的原子都倾向于,重新安排它们的价电子,使得分子有一个完整的,“八隅体“或者排满的外壳层。

So it's really neat to think that your counterparts 100 years ago right here at MIT could have been sitting in a class where they had Lewis as their lecturer, and he's putting forth these ideas -- these are actually his lecture notes, even though it wasn't even published yet, and giving this idea of Lewis structure, which is exactly what we keep using today in order to make a lot of these predictions.

因此会有很棒的感觉，当想一想一百年以前像你们一样,在这上学的同学可能正坐在教室里,听路易斯讲课，而他正在提出这些想法-,-而这些正是他的课堂讲义，尽管当时还没有发表，但已经给出了路易斯结构的思想，这正是我们直到今天都一直在用的,用它来做很多预测。

So, that's his gift to us: the Lewis structure, and the idea that you could share electrons and form a covalent bond.

这就Lewis给我们的礼物，Lewis结构，你能够通过公用电子,形成共价键。
