How did you feel after taking the Eurostar, regarding its service and the like?
你坐欧洲之星后感觉怎么样，关于它的服务和其他的方面？
-
The fact that I have this star here, this star here, this star here, is really just 'cause I'm a little anal and it looks pretty to make a little box out of everything but it's not strictly necessary.
事实上大家可以看到，这有颗星，这有颗星，这有颗星，其实是我手痒,这看起来像是用*围成个框，把它们包围起来,其实这是完全没有必要的。
-
So any time you see a star that means an anti-bonding orbital.
任何时候你看到有个星，这意味着它是反键轨道。
-
He was fascinated with astrolabes and was interested in sailing.
他着迷于星盘,并对航海很感兴趣
-
So as a first pass, the Evening Star is the first star that's visible and the Morning Star is the last star that's visible at the right times of the year.
在最初,昏星是能看到的,第一颗星,而晨星,是最后一颗,当然是在每年的特定时段

Okay, the Venti size Starbucks Strawberries and Cream Frappuccino.
好吧,超大杯星巴克草莓星冰乐

This is sigma star with the antibonding orbital that came from 1s, and it is a molecular orbital.
这是sigma星，来自于1s的反键轨道,它是一个分子轨道。

and then by Eurostar and total of 5-hour travel.

-
and that’s on Lexington and 25th street.
柏鲁克分校是在莱克星敦，25号大街。
-
So if we square sigma 1 s star, we flip the amplitude so it's all positive now, but again we still have this node right in the middle.
如果我们平方1s星，我们把振幅翻转所以现在都是正的，但同样在中间有个节点。
-
You can see that we have two unpaired electrons in this molecule here one in the pi 2 p x star, and one in the pi 2 p y star orbital.
你们可以看到我们这个,分子力有两个未配对电子,一个在π2px星，一个在π2py星轨道。
-
So if we talk about the probability density and we write that in, it's going to be sigma 1 s star squared, 1sb so now we're talking about 1 s a minus 1 s b, all of that being squared.
如果我们讨论概率密度，而且我们把它写出来，它等于sigma1s星的平方，现在我们说的是1sa减去，这整体再平方。
-
So we're going to call this the sigma 2 p x star, or if we're talking about the 2 p y orbitals we'll call this the pi 2 p x star, and the pi 2 p y star.
我们叫这个sigma2px星，或者如果我们说的是π2py轨道的话,我们叫这个2px星，这个π2py星。
-
sigma Here is sigma star, sigma, sigma star and sigma.
这是sigma星，sigma，sigma星，和。
-
And the pi star orbitals result from any time you have destructive py interference from 2 p orbitals that are either the p x or the p y.
星轨道是由于2p轨道的相消干涉,不管是px还是。
-
So this is the 1 s star, sigma 1 s star orbital, and what you have in the center here is a node, right in the center between the two nuclei.
这是1s星，sigma1s星轨道，中间这个是节点，它在两个原子核中间。
-
When we talk about anti-bonding, 1sb essentially we're taking 1 s a and now we're subtracting 1 s b, sigma1s and what we end up with again is sigma 1 s, and the important thing to remember is to write this star here.
当我们讨论反键时，本质上我们是用1sa减去，最后我们得到，记住这里有个星。
-
So that's the reason I am taking Eurostar.
所以，这就是我为什么要坐欧洲之星的原因。
-
In contrast, if we have destructive interference, what we're going to form is a sigma 2 s star, and what does the star designate?
相反，如果我们是相消干涉，我们会形成sigma2s星，星代表什么？
-
So this is still a sigma it's a sigma 2 p z star orbital.
这还是一个sigma轨道,它是sigma2pz星轨道。
-
What do you think about using Eurostar?
你觉得坐欧洲之星怎么样？
