So, first, if I point out when l equals 0, when we have an s orbital, what you see is that angular part of the wave function is equal to a constant.

首先，如果ｌ等于０,那就是ｓ轨道，你们可以看到,它波函数的角度部分是一个常数。

Specifically, we'll talk more about this, it's talking about different orbitals, it's the spatial part of an orbital.

特别地，我们将会谈到它，谈论有关不同轨道的问题，它是一个轨道的空间部分。

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。

In contrast when we're looking at a p orbital, so any time l is equal to 1, and you look at angular part of the wave function here, what you see is the wave function either depends on theta or is dependent on both theta and phi.

相反当我们看ｐ轨道时，任何时候ｌ等于１,你们看它的角向波函数，你们可以看到它要么是和theta有关,要么是和theta和phi都有关。
