因为极紫外线的波长在100å到1000å之间（注一）是会被大气中的臭氧层吸收，可是氢原子的 来曼系 （ Lyman series ）都是落在紫外线区域，宇宙大部分成分又是氢，对于研究宇宙的天文学家，臭氧层似乎不太讨他们喜欢。

Lyman series
- abstract: In physics and chemistry, the Lyman series is the series of transitions and resulting ultraviolet emission lines of the hydrogen atom as an electron goes from n ≥ 2 to n = 1 (where n is the principal quantum number) the lowest energy level of the electron. The transitions are named sequentially by Greek letters: from n = 2 to n = 1 is called Lyman-alpha, 3 to 1 is Lyman-beta, 4 to 1 is Lyman-gamma, etc.

-
We can think about the Lyman series.
我们可以来看看莱曼系。
-
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。
