Because here what we have is some atom that we're studying, in the case, it's going to be a gas, and we hit it with a photon that has some incident energy.
因为这里我们要研究的是一些原子,在这种情况下,一般是气态的,然后我们令一个,具有一定初始能量的光子打上去。
It's 109 . 5 is what we would expect for methane because it's tetravalent, but here we're just seeing something that's divalent, and they're both in p orbitals that are perpendicular to each other.
因为甲烷是四价的,我们预测是109。,但这里我们,看到的是二价的,它们都在。
"Everybody used that picture as a motivational tool of why we're truly here, because regardless of what's going on and how devastating it is, there are still people that recognize and believe that the Comfort is here to help them."

And I found that that increases their knowledge and understanding of actually what the company does tremendously, because somebody comes in, presents for an hour, "Here's what we're doing in China."
我发现,这在很大程度上增加了,他们对公司的认识,因为某位董事会做一个小时陈述,这是我们在中国的业务“
"Our effort here in writing this letter is just urging caution because we're hoping that with the new administration, we will have an administration that will lend itself more to diplomacy and working through other means rather than always military confrontation,".

We're going to be talking about these in finance in regards to returns because-- generally the idea here is that we want high returns.
接下来我们讨论它们在金融学中的应用,从收益的角度来说,一般我们都渴望高收益
Now, as we know, and by the way we're not going to write a perfect simulation here, because we're going to try and do it in 40 minutes, or 30 minutes.
现在u,我们知道,我们并不是要写一个,完美的仿真程序,因为我们得,在40或者30分钟内完成它。
so it's important to note that it's not in b, now we're talking about b plus, because we've already taken an electron out here.
其中有一个非常重要的地方需要注意,不是硼,而是正一价硼离子,因为我们已经拿走了一个电子了。
But instead in this chemistry course, I will just tell you the solutions to differential equations. And what we can do is we can start with some initial value of r, and here I write r being ten angstroms. That's a good approximation when we're talking about atoms because that's about the size of and atom.
但在这个课里,我会直接,告诉你们微分方程的解,我们可以给距离r一个初始值,我这里把r取10埃,当我们讨论原子时,这是一个很好的近似,因为原子的尺寸。
So essentially, each of these orbitals come from linear combinations of all of the original orbitals, and it's hard to picture exactly how that happens, but one that you can at least start to get an idea is if you think about combining the 2 s and the 2 p z here, which is not quite accurate because of course, we're combining all of them.
本质上,这些轨道每个都来,自原来所有轨道的线性组合,我们很难想象这是怎么发生的,但你们可以至少有个概念,如果你们考虑2s和2pz轨道的结合,这当然是不太准确的,因为我们要把所有的都组合起来。
