发射光谱分析中涉及谱线强度的机理讨论时,光源中的电离参量有重要的作用。着眼于定量讨论光谱分析光源中的电离问题已有较长一段时间了,但在国内某些文章或专业书中至今还常沿用着关于电离问题的初始概念及数据,不利于有关机理的讨论。本文对电离参量作扼要说明后提供一些在光谱分析真实条件下光源中元素电离度大小的数据,希望有助于对电离问题的理解。
When discussing the mechanism of spectral line intensity in emission spectroscopy, the ionization parameter in the light source plays an important role. It has been a long time since we discussed the quantitative analysis of ionization in spectroscopic light sources. However, the initial concepts and data on ionization are still used in some articles or books in our country so far, which is unfavorable to the discussion of the mechanism. This article gives a brief description of the ionization parameters and provides some data on the degree of ionization of the light source under the real conditions of spectral analysis, hoping to help understand the ionization problem.
