What I am going to do is use these postulates and go through the basis for the Bohr model.
接下来我要利用这个假设,检查波尔模型的根据。
All right. The other thing I have to teach you is matter-energy interaction so that we can see how the Balmer series validates the Bohr model.
好的,我要教你们的里一个知识点是,物质能量的相互作用,我们可以见证,巴尔末线系是怎样证实波尔模型的。
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。
How does this support the Bohr model?
那这是如何支持波尔模型的呢?
If you go to Denmark and you break a $100 bill, you're going to be given one of these, undoubtedly, the 500 kroner note, which is worth about $75-80, and it has Niels Bohr on it.
如果你去了丹麦,换了100美元,毫无疑问,你会得到其中一个像这样的,500挪威币,约为75-80美元,上面有波尔的头像。
And Rutherford, who I have already described to you as being a little bit colorful in his language, backed up Bohr on this.
而卢瑟福,就是以前我跟你们提过的那个,语言丰富生动的人,在这一点上证实了波尔的理论。
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。
So Bohr was validated in very, very strong measure, but there were also some contrary data.
所以说波尔理论得到了强有力的证实,但其实也存在一些反面数据。
And the 0.0016 is greater than what I would have as experimental error, so your theory is wrong. Bohr says oh, yeah?
。0016比,我检测出来的错误大得多,所以你的理论是错的,波尔说,哦,是吗?
There is Bohr at the center, and there is Heisenberg who is the one electron orbiting the center.
波尔在中间,这儿是海森堡,就像一个电子围绕着中心运转。
So anyways, Bohr ascended to the heights achieved only by Einstein.
无论如何,波尔到达了一个高度,仅仅只有爱因斯坦能到达。
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。
This one is calculable by the Bohr model because lithium 2plus is a one electron system.
这个可以通过波尔模型计算而得到,因为锂2+是单电子系统。
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。
So, someone says I didn't understand what he was talking about at the end of the last lecture when he was doing the Bohr model.
所以,有人会说,我不理解老师,在上节课末尾说的内容,当他在做玻尔模型的时候。
Bohr expressed the quantum condition by the angular momentum, quantum condition in the following manner.
波尔阐明了他的量子理条件,通过角动量,和以下的量子条件进行量子化。
I never got invited to their place so I don't know them Bohr liked music.
我从来没有被邀请过去,因此我不认识他们,波尔喜欢音乐。
Bohr started talking about quantization.
920年波尔开始讨论量子学。
Pauli was an Austrian who did his PhD under Sommerfeld in Munich and then post-doced with Max Born in Gottingen and also with Niels Bohr in Copenhagen.
泡利是个奥地利人,他在慕尼黑读博的时候导师是索末菲,他后来从医的时候,在哥廷根和曼克斯·波恩共事,在哥本哈根的时候和尼根斯·波尔共事。
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, you recall in Bohr the quantum condition.
现在,回忆一下波尔量子理论。
There is a Homburg and there is a Borsalino, Here's Bohr mixing it up with royalty.
一个是汉堡帽,一个是博尔萨利诺帽,这是波尔和皇室人员。
If you look really carefully, you could find it was not a single line but two lines, and Bohr is silent on such matters.
如果你仔细观察的话,会发现这是两条谱线而非一条,对这一研究,波尔不得不沉默。
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。
