We will always have r equals zero in these radial probability distribution graphs, and we can think about why that is.

在这些径向概率分布图里,总有ｒ等于０处，我们可以考虑为什么会这样。

Or we could just look at the radial probability distribution itself and see how many nodes there are.

或者我们可以直接,看径向概率分布图,本身看看里面有几个节点。

And you can see this expanding rings of activity of stimulating, Cause a pattern of activities that move forward from the back of the brain to the front of the brain, in a very regular pattern which we call a visual field map.

眼睛在前面，指向这个红点，大家看到，刺激活动不断扩大的环路,引起一个活动的模式，从大脑的后不向前部移动，这一模式十分规律，我们可以称其为视觉分布图。

So we talked about radial nodes when we're doing these radial probability density diagrams here.

我们画这些径向概率分布图的时候,讨论过径向节点。

But there's also a way to get rid of the volume part and actually talk about the probability of finding an electron at some certain area within the atom, and this is what we do using radial probability distribution graphs.

除去体积部分,来讨论,在某些区域内,发现一个原子的概率,我们可以，用，径向概率分布图,它是。

So, there are 2 different things that we can compare when we're comparing graphs of radial probability distribution, and the first thing we can do is think about well, how does the radius change, or the most probable radius change when we're increasing n, when we're increasing the principle quantum number here?

当比较这些径向概率分布图,的时候，我们可以比较两个东西，第一个就是考虑当我们增加ｎ,当我们增加主量子数的时候，半径怎么变，最可能半径怎么变化？
