All right, so we're into bribing you as we go along here, and all right?
好,因此我们会在,我们课程进行的途中一直收买你们,怎么样?
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。
The men are temporary residents at a migrant safe house the first in a series that stretches from here north, through Mexico, along the most frequented routes used by migrants traveling to the United States.

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
You can see some of the points I've made along the blue line here.
你们可以看到我在蓝色曲线上标出了几个点。
You've got these warehouses along the canals and here's where the bankers-- the Dutch had the most, along with the English, had sophisticated banking system in the world.
你已经见过了这些运河旁的仓库了,这些银行家们,大部分来自于荷兰,同时也来自英国,他们拥有世界上最复杂的的银行系统
Here I am going along.
情况就是这样。
- 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?
Now, here, these are houses that are built along the canals.
再看这个,这个是造在运河旁的住宅楼
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。
