We can go back to ancient Egypt where there khemeia is reference in the hieroglyphs to term khemeia, which, among other things, meant chemical processes for embalming the dead.

我们可以追溯到古埃及,那的象形文字提到了词语,这是，在其他事情当中，意味着,化学过程处理防腐尸体。

All right. So now that we have a general idea of what we're talking about with shielding, we can now go back and think about why it is that the orbitals are ordered in the order that they are.

现在我们对于谈论的屏蔽,有一个整体观点了，我们现在可以回过头来考虑,为什么轨道是按照,那种规则排列的。

We can go back and forth between these two equilibrium states They're connected.

我们可以,在这两个平衡态间往返,它们是相互联系的。

Can I have a teachnic assistance to--to All right.We'll go back here to try this.

有人能提供技术支援吗,好的,我会再尝试一遍

What we're really getting at is the idea of saying I want to have a way of grouping together information into units that make sense. So I can go back to one of those topics we had at the beginning, which is the idea of abstraction, that I can create one of those units as a simple entity, bury away the details and write really modular code.

组合成为有意义的单元,那么这就让我们回到,一开始讲的话题之一了,这就是抽象的概念,也就是我可以以一个简单的，实体的形式创建这样的一个单元，把具体实现隐藏然后写一些,真正模块化的代码,我们在以后的课程中。

x and y can be whatever you like, but I picked a very special example You should go back and remember what we did.

你可以任意选取 x 和 y,但我这里讲个特例,你们应该回忆一下上节课的内容

So now we can go back and think about filling in these electron configurations for any atom.

实用现在我们返回来再考虑,关于填充任意原子,电子构型的问题。

So we won't do it for this molecule, but we'll go back and do it for some of our other examples, and you can go back and do it for this one.

因此对于这个分子我们就不做这一步了，但是对于其它的例子我们会回来做这一步的，而对于这个，到时大家也可以回来做一下。

So, if you can flip your lecture notes over and just write on the blank space, we're going to cover electronegativity first here, and specifically, you can go back and fill this in to your lecture 9 notes, if you want to stay organized, but I just suggest just writing it on lecture 10 notes now and going back.

因此，请大家把讲义翻到背面,就在空白处做一下笔记，我们要先讲一讲电负性，特别提醒一下，大家可以,回到第九课的讲义并把这些记在那里，如果你想保持条理性的话,但是我建议大家先写在第十课的讲义上,回去再记到第九课的讲义上。

OK, I think we can safely go back to notes.

好的，我想我们可以放心地继续讲下面的内容了。

So, that's sort of the mathematically how we get to a, but we can also just look at the graph here, because every time we go one wavelength we can see that we're back in a maximum.

这是就我们得到a的数学,办法，但我们可以直接,从图上看，因为每次我们,经过一个波长，都回到一个最大值。

Now, we are done because now we can ask how high does it go, and you go back to your y of 1 is 15+10-5, which is what?

现在问题解决了,因为我们可以算出,最高点的高度,你回到这个式子,求出y=15+10-5,是多少
