概述了氩-氢辉光放电等离子体中可能发生的各种过程，包括根据文献汇编的横截面和速率系数。基于简单的平衡方程，可以估计典型 GD-MS 和 GD-OES 条件下的 H2 解离度。此外，还预测了 H2 分子和 H 原子对氩分析辉光放电的影响，即氩离子（也可能是电子）密度的下降、氩亚稳态原子密度的下降以及电子能量分布函数的变化。基于这些预测效果，我们尝试解释观察到的分析特征的变化。
An overview is given of the various processes which may occur in an argon–hydrogen glow discharge plasma, including the cross sections and rate coefficients compiled from the literature. Based on a simple balance equation, the dissociation degree of H2 is estimated for typical GD-MS and GD-OES conditions. Further, the effects of H2 molecules and H atoms on the argon analytical glow discharge are predicted, i.e., a drop in argon ion (and maybe electron) density, a drop in argon metastable atom density and a change in the electron energy distribution function. Based on these predicted effects, we try to explain observed changes in analytical characteristics.
