【摘要】 本文讨论磁场中中等低气压弧光放电与辉光放电的正柱理论。文献[1]是给定放电中间参数后,假定中性气体运动,研究放电现象.本文仍假定中性气体运动,但给出初始放电参数,补充两个积分关系,建立了初始放电参数与中间参数的关系。给出这个问题完整的数学提法。用数值方法求解。文献[1]相当于第一次迭代。结果表明,这种改进是必要的.更多还原

【Abstract】 A theory of positive column in glow discharge and arc discharge under moderately low pressure in a magnetic field is presented in this paper. In Ref. [1], the discharge phenomena are investigated under the assumption that the neutral gas is in motion’ with a set of given intermediary parameters. It is still assumed hear that the neutral gas is in motion, however initial parameters are given, two integral equalities are derived, and relations between initial parameters and the intermediary ones are established. A complete mathematical formulation of this problem is presented and a solution; is obtained numerically. Ref. [1] is equivalent to the firet iteration. The results shove that this kind of improvement is necessary.更多还原
