And it turns out that when you constructively have two p orbitals interfere, and when I say constructively, I mean they're both either positive or they're both the negative lobes, that's when you got bonding.

当两个ｐ轨道,相长干涉时，我说的相干相长，意思就是说它们要么都是,正的叶瓣要么都是负的叶瓣，这时就能成键。

So if we have constructive interference between the two, what we're going to see is our molecular orbital looks something like this.

如果两者是相干干涉，我们看到分子轨道,看起来是这个样子的。

So in this case where we're adding it together, this is going to be constructive interference.

在这个情况下，我们把它加在一起，这是相干干涉。

So in this case the cross term represents constructive interference between the two 1 s atomic wave functions.

在这种情况下交叉项代表两个,1s原子波函数的相干干涉。
