But you notice up here how close these levels are, so we are looking at very, very fine distinctions.

你能看到这些层有多接近，所以我们是在观察非常非常细微的差别。

So then you could explain in terms of these levels.

你可以用这些层级来解释。

So as I tried to say on the board, we can have n equals 1, 1/2 but since we can't have n equals 1/2, we actually can't have a binding energy that's anywhere in between these levels that are indicated here. And that's a really important point for something that comes out of solving the Schrodinger equation is this quantization of energy levels.

我在这要说的是，我们可以让n等于，但不能让n等于,我们不能得到在这些标出来的,能级之间的结合能，能级的量子化,是从解薛定谔方程中,得到的很重要的一点。

The interesting thing is that through time, as political winds change, these taxes have changed and they've gone up to some very high levels in the past in the United States and other countries.

So what we'll start with today is talking about the technique that's primarily used to actually experimentally figure out what these different energy levels are.

因此，我们今天首先要讨论的就是,最常用来在实验上,确定不同能级的技术。

So, if we start instead with talking about the energy levels, we can relate these to frequency, because we already said that frequency is related to, or it's equal to the initial energy level here minus the final energy level there over Planck's constant to get us to frequency.

如果我们从讨论能级开始，我们可以联系到频率上,因为我们说过频率和能量相关,或者说等于初始能量,减去末态能量除以普朗克常数。

And even though he could figure out that this wasn't possible, he still used this as a starting point, and what he did know was that these energy levels that were within hydrogen atom were quantized.

这是不可能的了,但他还是以此为出发点，他知道，氢原子的这些能级,是量子化的,而且他也知道，我们上节课所看到现象。
