And in terms of radial nodes, we have 2 minus 1 minus 0, so what we have is one radial node.

对于径向节点，我们有２减去１减去０,所以有一个径向节点。

So what we should expect to see is one radial node, and that is what we see here 3s in the probability density plot.

个节点,这就是我们，在这概率密度图上所看到的,如果我们考虑。

So that's why we have this zero point here, and just to point out again and again and again, it's not a radial node, it's just a point where we're starting our graph, because we're multiplying it by r equals zero.

这就是为什么在这里有个零点，我需要再三强调，这不是径向零点，他只是我们画图的起始处，因为我们用ｒ等于０乘以它。
