The advantage of this is that now you have four binding sites for antigen instead of just two.

这样的好处是一个抗体上,有四个抗原结合位点而不仅仅是两个

What we do care about is the energy of our orbitals that have electrons in them, and if we combined all four of the orbitals, then our hybrid orbitals would have more p character to them, so they'd actually be higher in energy.

是不是很高,我们不关心它的能量很高，我们关心的是，有电子的轨道的能量，如果我们把四个轨道结合。

So in s p 2 hybridization, instead of combining all four, we're just combining two of the p orbitals with the s orbital.

这样就能得到sp2杂化，在sp2杂化中，不是四个轨道结合。

All right, so that's s p 3 hybridization, but those aren't the only type of hybrid orbitals that we can form. Let's take a look at what happens if instead of combining all four orbitals, we just combine three of those orbitals, and what we'll end up with is s p 2 hybridization.

好了，这是sp3杂化，但这并不是我们可以,形成的唯一类型的杂化轨道,让我们来看看，不是四个轨道结合，我们仅仅结合3个轨道。
