global c Well, let's go ahead and open up global dot c, or you can follow along up here.
好的，我们继续打开，或者你们可以跟随这里个地方。
-
Remember this is our bond axis here, and you can see there is this area where the wave function is equal to zero all along that plane, that's a nodal plane.
记住这是我们的键轴，你可以看到在这些区域,波函数在这个面内全都是零，这是节点面。

Let's some--let's go ahead We're going to move this along just a little bit here.
我们继续,我们继续往后听
-
Speaking of behavior, I have to maintain a fertile learning environment in here. We've got round numbers in excess of 400 people sitting here, so I expect certain things here, and that's how we're going to get along.
说到行为，我要维护一个良好的学习环境,我们的人数有点多,400人坐在这，所以，我期待一些事情，那就是我们相处的方式。

-
Here I am going along.
情况就是这样。
-
b OK. In this example I'd use b. All right, as b get-- b is the thing that's changing as I go along here, but it could be things like, how many elements are there in a list if the input is a list, could be how many digits are there in a string if the input's a string, it could be the size of the integer as we go along. All right.?
好，在这个例子里我会用，因为b是一直在变的东西,但是也可能是如下情况：,如果输入是数组的话,变化的就是数组的元素数，如果输入是字符串的话,变化的就是字符串的长度，如果是integer的话,可能就是这个数的大小，对不对？
-
- 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？
-
d1 2 3 And we can do that just going along, 3 d 1, 2 3, and the problem comes when we get to chromium here, which is instead of what we would expect, 4s23d4 we might expect to see 4 s 2, 3 d 4.
我们能做的就是继续，问题出现了,当我们来到铬元素时，它不是我们预期的那样，我们可能预期。

The interesting thing here is that the bass continues along with the duple pattern.
有趣的是,低音部还是按二拍模式进行
-
If we have a particular rhythm, and this is a rhythm, and here are the beats and the meter underneath, we would be coming along one, two-and, one, two.
如果我们有一段节奏,这里就有一段节奏,而下面标明了节拍和拍子,我们就能一二,一二

So we're going to hear a solo by Louis Armstrong now and let's count along once the phrase begins. I'll get you started and then you count the measures. Here we go.
下面我们听一段路易斯·阿姆斯特的独奏,同时音乐起奏时,我们就开始数,我会提示你们开始,然后你们开始数小节,准备好
-
The reason that it's sigma is if you look at the bonding axis here, is that there is no nodal plane along the bonding axis.
它是sigma键的原因是,因为如果你看键轴，上面是没有节面的。
-
But in sigma orbitals, you have no nodal planes along the bond axis, so if we had a nodal plane here, we'd see an area where the wave function was equal to zero.
但在sigma轨道里，沿着轴向是没有节点平面的，如果我们有个节点，我们就会看到某个地方波函数等于0。
-
All right, so what we see here is we have our sigma bond that's along the internuclear axis here, but we also have a pi bond, because each of these atoms now has electrons in it's in a p orbital, so we're going to overlap of electron density above and below the bond.
这里我们看到sigma键,是沿着核间轴的，但我们还有一个π键，因为每个原子的p轨道上,都有电子，所以电子密度在键的上面,和下面都有电子密度交叠。
