a0 This is equal to a sub nought for a hydrogen atom, and we remember that that's just our Bohr radius, which is . 5 2 9 angstroms.

它等于,我们记得，这就是波尔半径,也就是0，529埃，实际上。

So if we superimpose our radial probability distribution onto the Bohr radius, we see it's much more complicated than just having a discreet radius.

为波尔半径,这其实比分立的轨道,要复杂很多，我们可以有任何的半径,但有些半径的概率。

We can make some substitutions here using some of the derivation on the previous board which will give us the Planck constant divided by 2 pi mass of the electron times the Bohr radius.

在这里我们也可以,用我以前在黑板上写过的一些词来取代它,得到的是普朗克常数除以2π电子质量,再乘以波尔半径。

And remember, a nought, that's just the Bohr radius, that's all we need to worry about.

记住ａ０就是波尔半径，我们要记住这点。

The Bohr radius, for hydrogen is 0.529 angstroms.

波尔半径，对于氢原子来说是0。529埃。

And basically, what that means is you can actually find an electron anywhere going away from the nucleus, a0 but you're most likely to find that you have the highest probability at a distance of a sub nought, or the Bohr radius.

它说明，虽然你可以,在任何地方,找到电子，但在距离为,或者波尔半径的地方,找到电子,的概率最大，我说过。

There is the Bohr radius down there, number 24.

有波尔半径在第24个。

For the 2 s orbital, at 2 a nought, a0 so it's just 2 times that constant a nought, which is the Bohr radius.

也就是，乘以常数,玻尔半径，对于3s轨道。

And this quantity is termed the Bohr radius.

而这个量被叫做，Bohr，半径。

And what he came out with when he did some calculations is that there's the radius that he could calculate was equal to this number a sub nought, which is what we call the Bohr radius, and it turns out that the Bohr radius happens to be the radius most probable for a hydrogen atom.

等于这个a0的值,我们叫它波尔半径，而,波尔半径恰好是,最容易，找到电子的地方，我们对波尔模型,不做过多的解释,这是因为。
