We got them from combining again, 1 s orbital and the 3 p orbitals. If we hybridize these, what we end up seeing are these four hybrid orbitals.

我们把1s轨道，和3p轨道结合而得到它们，如果我们杂化它们，我们最后会看到4个杂化轨道。

int A Well, one, function has called swap, takes one int called A, printf followed by another int called B, and as we've seen with print F, if you have multiple arguments, you separate them by commas.

好的，函数叫做swap，一个参数是，另一个参数是int，B，我们看到的,如果你有好几个参数，把它们用逗号分开。

You can see if we combine the s with the top lobe of the p, they're going to constructively interfere because they have the same sign.

你们会看到如果我们把s轨道和p轨道的上叶结合，它们是相长干涉,因为它们负号是相同的。
