And again, we can define what that most probable radius is, that distance at which we're most likely to find an electron.

同样的，我们可以定义最可能距离，在这里找到电子的概率最大。

You can see how they moved from that definition of probability to the current definition.

所以你可以清楚地了解到,概率是如何由那个定义,转变为今天的定义的

So, basically what we're saying is if we take any shell that's at some distance away from the nucleus, we can think about what the probability is of finding an electron at that radius, and that's the definition we gave to the radial probability distribution.

本质上我们说的就是,如果我们在距离原子核,某处取一个壳层，我们可以考虑在这个半径处,发现电子的概率，这就是我们给出的,径向概率密度的定义。
