And in this context, the length of that array is stored in Arg C. Well, let's take a look at a slight variance of this that reveals further what we can do and reveals what a string really is.

关于这点，那个数组的长度被存储在ArgC中,好的，让我们看看这个轻微的变化,那个揭示了我们可以做的,和字符串实际上是什么。

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。

And I picked looking at methane so we could see if there are other factors that we're not considering, that we need to maybe tweak our model a little bit, and I think we'll find that we do if we take a look at a polyatomic molecule, methane, CH4 so c h 4.

我选择甲烷这个例子，我们可以看到,如果有一些我们没有考虑到的因素，我们需要修改一下我们的模型，我们看一看,甲烷CH4这个多原子分子，就会知道这一点，甲烷。
