In an orbital is remember that this area right here at r equals zerio, that is not a node.

例如对于１ｓ轨道,记住这里ｒ等于０处不是一个节点。

And, in fact, these are the only two types of nodes that we're going to be describing, so we can actually calculate both the total number of notes and the number of each type of node we should expect to see in any type of orbital.

事实上，我们只,描述这两种节点，所以我们可以,计算任何轨道中的,总结点数以及各种节点数。

So that's why we saw, for example, in the p orbitals we had one angular node in each p orbital, because l is equal to 1 there.

这就是为什么在ｐ轨道中,每个轨道节点数都是１,因为这里ｌ等于１．
