"I think the hardest thing was combining those two things and then figure out what the hell we were going to jettison.

px So we're talking about pi carbon 2 p x, 2px because it's the x axes combining to carbon 2 p x.

我们讨论的是π碳，因为它在x轴结合成碳。

All right. So, let's look at this in another way, sometimes it's hard to picture these waves combining.

好的，让我们从另外一个方面来看，有时候很难想象这些波函数的组合。

What a delight to be able to spend a few minutes with you and such a very special class, where you are combining the science of positive psychology with its practice.

和你们共度几分钟，真是乐事,在这样特别的课堂上，在这里你们将积极心理学的科学,和应用合二为一。

So, we see is when we use the octet rule to look at fluorine molecule, we're combining two fluorine atoms, and what we end up with is an f f molecule where they're sharing two electrons, so making that covalent bond.

那么，我们看到把八隅体规则用到氟分子上,就是把两个氟原子组合起来，最终得到的氟分子中两个原子,共用一对电子，这就构成了共价键。

And if we think about the six hydrogens, now each of those are going to bind by combining one of the carbon hybrid orbitals to a 1 s orbital of hydrogen.

如果我们考虑有六个氢原子，每个都会合起来,碳杂化轨道成键,每个氢的1s轨道。

Oh, and actually before you skip your page in the notes, I realized I should write out for you what the addition is to start with. So, when we're combining two waves, 1sb what we have is 1 s a that we're adding together with 1 s for b, the second atom.

在你们翻过这页讲义之前，我觉得我应该写出加法,当我们把两个波函数放在一起时，我们用1sa加上，第二个原子。

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。
