Ar/H2和Kr/H2混合体系电子群参数的计算
Calculation of Electron Swarm Parameters in Ar/H2 and Kr/H2 Mixtures
摘要：
为了建立气体介质中的放电模型，必须知道一些基本的数据，如：粒子模型中的电子碰撞截面，流体模型中的电子群参数。对于基于电子能量分布函数的一阶矩和二阶矩的流体模型来说，所有电子群参数作为约化电场的函数的知识是必不可少的。本文的目的是计算Ar/H2和Kr/H2混合气体的迁移率、特征能量和电离系数。所获得的结果将与不同作者已经进行的测量进行比较。
英文摘要：
To develop the modeling of electrical discharges in a gaseous medium, it must to know a numbers of basic data such as: the electron collision cross sections for particle modeling or the electron swarm parameters in the case of the fluid modeling. The knowledge of all the electron swarm parameters as a function of the reduced electric field is indispensable for the fluid models based on the first and the second moment of the electron energy distribution function. The objective of this work is to calculate the mobility, the characteristic energy, and the ionization coefficient in the case of the mixtures Ar/H2 and Kr/H2. The results obtained will be compared with measurements already made by different authors.
