And so this lower level is called a bonding orbital, and it is a bonding molecular orbital.
所以能级较低的轨道叫做成键轨道，这就是成键分子轨道。
-
So any time you have two atoms bonding, the bond axis is just the axis that they're bonding along.
任何时候如果你有两个原子成键，键轴就是它们成键的方向。

It would be that kind of thing kind of head charts, general plans and within that general plan a lot of freedom of expression.
可能就是这样成曲的,一个起调,一些笼统的计划,其间有很大余地可以自由发挥的
-
So the result is we can combine all of these as a single differential, and just like we've seen before, what that suggests is that we define another new quantity given by this expression.
结果就是我们能把所有的结果,整理成一个单一的微分，就像我们前面看到的一样，这说明我们可以利用这个式子,定义一个新的物理量。

-
It's what it's called when an atom takes both electrons in the bond.
这就是它为什么叫这个名字,当一个原子从成键中得到两个电子。
-
The way in which we put signs together is to take these bundles, these binary relationships between a concept and a sound image, and adjust them in an unfolding sequence.
我们随意地将能指和所指捆在一起，也就是构成了一个事物和声音形象的关系，而且他们能被排列成话语。

Questions make a difference, which is why it is also important to ask the positive psychology question, which is the salutogenic question: ? "What is source of health? What is the source of success?
疑问引起改变，因此提问是非常重要的,提出积极心理学的问题很重要，也就是“健康创成“的问题：,“健康源于什么？成功源于什么？
-
So, you have this tremendous continuity between the sort of the honor code that was so dominant in the Homeric world, which has now been shifted to the larger unit, which is the polis.
现在你对荣耀法则的变迁应当有所了解了,荷马时期的主流是个人英雄主义,逐渐演变成现在对更广泛的集体,也就是对城邦的担当
-
It's as if this celestial laser beam were designed so as to actually shift the atomic structure of the pure corporeal frame of the virgin's body until that body is so rarefied, so pure and ethereal, that it's nothing but soul.
这束天国的激光好像被设计成,去把处女纯净肉体的原子结构,变的纯化，纯粹和飘渺，那就是灵魂。

> But if you actually do the math, those zeros and ones translate to an ASCII character which is D which is gonna be a 65, 66, 67, 68 would be the letter D.
>，你们自己算算看,把这些0和1转换成D对应的ASCII码,那么就是，65，66，67，68，对，68对应于“D“
-
So it's trigonal because we have these three atoms that are bound to the central atom here, and if you picture it, it's actually shaped like a pyramid.
这里三角形是因为,我们有3个原子核中心原子成键，如果你画它，它就是金字塔形的。
-
So what that means is that's how much energy we would have to put into a hydrogen molecule in order to get it to split apart into its two atoms.
它的意义,就是我们需要向一个氢分子中注入这么大的能量,才能将它分解成两个独立的原子。
-
So we know that it's 1, because we have 1, 2, 3, 4 bonding, minus 2 anti-bonding, and 1/2 of that is a bond order of 1.
我们知道它是，因为我们有1，2，3，4个成键，减去2个反键，它的一半就是键序为1。
-
And they wove them together into the form that we have now, and that is a process that is referred to as redaction or editing.
他们将它们编篡成我们现在看到的形式，这就是我们所说的编辑过程。
-
And step four is going to have us figure out how many bonding electrons we have, so we have 16 minus 10, is going to be 6 bonding electrons.
而第四步需要判断,我们有多少个成键电子，那么我们有十六减十，也就是六个成键电子。
-
So to figure out bonding electrons, -- what we take is that number 18, which is our total number of electrons we need to fill valence shells, and we subtract it from our number of valence electrons, which is 10.
那么为了找出成键电子，我们将十八，也就是填满所有价壳层,所需要电子的总个数，减去我们所有的价电子的个数，也就是十。
-
So we'll start to look at molecules and we'll see if we take two atoms and we fill in our molecular orbital and it turns out that they have more anti-bonding orbitals than bonding, that's -- a diatomic molecule we'll never see.
我们要看开始看一看分子,并且我们会发现如果我们,取两个原子并且填入分子轨道,结果是它们的反键轨道,比成键轨道更多，这就是-一个我们不会看到的二元子分子。

Further down this line here are embryonic or let's say adult brain stem cells.
沿着这条线再往后一些就是胚胎,或者就说是成人脑中的干细胞吧
-
And it's called divide and conquer for the obvious reason. I'm going to divide it up into sub-problems with the hope that those sub-problems get easier. It's going to be easier to conquer if you like, and then I'm going to merge them back. Now, in the binary search case, in some sense, this is a little bit trivial.
因此被称为分治的原因就这么简单,将一个问题分解成一些子问题,并希望这些子问题解决起来比较方便,正如你希望的，求解的过程也会变得简单,下面就是把结果合并起来,现在，在二分搜索的例子里,从某些方面来说，这有点微不足道。
-
The lesson is, I think, that we have a glamour-city phenomenon-- that excitement about real estate prices-- centered in places like Los Angeles, but it's spreading and becoming more and more of a national phenomenon and that's the bubble.
我想,教训就是,一种"魅力之都"现象,刺激了房地产的繁荣,起始于像洛杉矶这种城市,随后广为扩散,逐渐演变成一种全国性的现象,这就是泡沫
-
This is a mechanism by which an electrical signal comes here, it gets translated into a chemical signal, the chemical diffuses across the gap and reinitiates a - an electrical signal in the next cell and that's one way that it happens.
这就是电信号产生的机理,电信号翻译成化学信号,化学物质扩散过突触间隙,重新激起下个细胞中的电信号,这是一种方式
-
s2 So, I'm passing in the first character in s2, I'm making it uppercase and then I'm putting it back so casually speaking this is just capitalizing the first letter of whatever word the user typed in to s2.
那么，我把第一个字符传递给，我把它转换成大写的，然后存下来,简单说，这就是把用户输入s2中的单词,的第一个字母转换成大写的。
-
And then I convert that to mass, and that gives me 24.7 kg of titanium.
换算成质量，就是24。7kg的钛。
-
That's why in the earlier models of the atom, they're not horrible to sometimes think about just each n value as a little ring around.
这就是为什么在早期原子模型中，人们没有感觉到把每一个，n，都想象成,一个绕核的小圆圈有什么不妥。
-
When we talk about gene expression than we're talking about this whole sequence of events I just described: transcription, RNA processing, translation to make the protein.
当我们谈到基因表达的时候,我们就是在讨论,一系列我们刚才提到的过程,即转录,RNA加工,翻译成蛋白质
-
And when we talk about covalent bonds, there's 2 properties that we'll mostly focus on, and that's going to be thinking about the bond strength or the energy by which it stabilized when it bonds.
而当我们讨论共价键的时候，有两点特性是我们最关注的，那就是键的强度,或者说成键之后能量降低了多少。
