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。

So, doing those probability density dot graphs, we can get an idea of the shape of those orbitals, we know that they're spherically symmetrical.

概率密度点图上,我们可以对这些轨道的形状，有个大概了解,我们知道它们是球，对称的,我们今天不讲。

It makes sense to draw the wave function as a circle, because we do know that 1 s orbitals are spherically symmetric.

把波函数画成一个圆是有道理的，因为我们知道1s轨道是球对称的。

Well, essentially what that tells is that these s orbitals are spherically symmetrical.

实际上它告诉我们,这些s轨道,是球对称的。
