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。

Eventually, what they did was to separate these lines into more discreet places, or more discreet pitches.

最终,他们更把这些曲调线分割,安排在更确切的位置上,或者说更确切的音高上

So, what he did was kind of impose a quantum mechanical model, not a full one, just the idea that those energy levels were quantized on to the classical picture of an atom that has a discreet orbit.

还不是完整的,只是这些能级，是量子化的概念，作用到原子有分立轨道的经典原子模型上,当他做了一些计算后,他得到有个半径,他算出来。

Article in the September 29, 2008, of Washington Post said that and I quote, Joshua may be one of the most discreet White House Chief of Staff ever, seldom talking on the record to the press or appearing before outside audiences.

008年9月29日，华盛顿邮报的文章说到,我引用一下，约书亚可能是最谨慎的,白宫办公厅主任，他很少向媒体公开发表言论,很少出现在大众面前。

and he knew this the same way that we saw it in the last class, which is when we viewed the difference spectra coming out from the hydrogen, and we also did it for neon, but we saw in the hydrogen atom that it was very discreet energy levels that we could observe.

那就是,当我们看氢原子发出的光谱时，我们也看了氖气,但我们看到,氢原子能级是分立的，这些，在当时,已经被观察到了,他也都知道。

So, for example, when people, and we'll talk about this next class, were looking at different characteristics spectra of different atoms, what they were seeing is that it appeared to be these very discreet lines that were allowed or not allowed for the different atoms to emit, but they had no way to explain this using classical physics.

举个例子，当大家看到,不同原子的特征光谱时,他们看到的是一些分离的线,那可以使不同的原子,发射或不发射出去，但是这些无法用经典物理来解释。

And when we talk about l it is a quantum number, so because it's a quantum number, we know that it can only have discreet values, it can't just be any value we want, it's very specific values.

当我们讲，l是一个量子数时，因为它是量子数，我们知道，它只能去分立的值，它不能取到所有的数，它取一些确定的数。
