We ended the day with Bohr's model of the atom, which derived from the conceptualization of Rutherford.

那天课的结尾我们讲了从卢瑟福的概念中，衍生出来的波尔的原子模型。

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。

OK, this is the Bohr model, Bohr model of the atom is planetary or nuclear.

好的，这就是波尔模型，波尔的原子模型是行星模型或者核心模型。

So all that Bohr, for example, had to go on at this point was a more classical picture of the atom, as you can see on the left side of the screen there, which is the idea that the electrons orbiting the nucleus.

原子的经典图像，你们可以,看到屏幕左边，这是电子，绕着核子旋转，的概念,他已经知道。

Now, let's take a look at the Bohr model of the atom.

让我们看看波尔的原子模型。

So, I said I'd tell you a little bit more about where this Bohr radius came from, and it came from a model of the atom that pre-dated quantum mechanics, and Neils Bohr is who came up with the idea of the Bohr radius, and here is hanging out with Einstein, he had pretty good company that he kept.

我要告诉你们,波尔半径是从哪里来的,它起源于前量子力学时代的，原子模型,尼尔斯，玻尔提出了，波尔半径的概念,这是他和爱因斯坦在一起，他们是好朋友，当我们讨论这个原子模型时你们要记住的是，在1911年。

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。
