So, ideally what we did see was, in fact, it does have enough energy with the UV lamp, it wasn't a dramatic shift you saw because we didn't start very high and then it went to that stuck point.
所以,理想上我们所看到的,事实上,紫外灯没有足够的能力,因为我们没有从非常高开始,所以它没有一个特别显著的移动,然后它又回到了黏着点。
We have a UV lamp right here, which is centered at a wavelength of 254 nanometers.
我们有一个紫外灯在这里,波长集中在254纳米处。
We can think about the Lyman series, which is 1 where n equals 1. We know that that's going to be a higher energy difference, so that means that we're going to be in the UV range.
我们可以来看看Lyman系,也就是n等于,我们知道它的能量差更大,所以它在紫外光区内。
