The graph to the left, this is the s orbital, symmetric.

在左边的图是对称的S轨道，对称的。

This is the radial probability distribution formula for an s orbital, which is, of course, dealing with something that's spherically symmetrical.

这个ｓ轨道的,径向概率分布公式，它对于球对称,的情形成立。

And in the case of the 3 s orbital, that's going to be equal to 11 . 5 times a nought.

对于３ｓ轨道，它等于１１．５ａ０．

So here we have 3 minus l equals 0, because it's an s orbital, minus 1, so we have two radial nodes here.

这里我们有３减去ｌ等于０,因为这是ｓ轨道，减去１,我们有两个径向节点。
