So you see in the hybrid orbital we actually have a larger lobe on top where they constructively interfered.

所以你们可以看到在杂化轨道里,我们上面,由很大的一叶相长干涉。

If you compare the s orbital with the bottom lobe, these have a different sign so they're going to destructively interfere.

如果你们比较s轨道和下面这叶，它们正负号相反，所以它们相消干涉。

So what you see is actually a diminished lobe on the back part of this s p 3 orbital.

你们看到,在sp3轨道的后面部分,有个小叶。
