项目摘要

1. Determination of the spatial distributions for produced excited particlesThe spatial distributions for produced excited particles are determined using a Monte Carlo Simulation method. The calculations are expanded to the region, which include non-equilibrium condition of electron energies. The behavior of electron swarms in Ne/Ar mixture, Ne, Ar and N_2 are investigated.2. Loss process of excited particleThe loss process of excited particle have studied by means of the analytical method, which solves the diffusion equation under the third kind boundary condition for N_2(A^3*^+_u). From the result of this analysis, we confirmed the reflection phenomena of excited particles at the boundaries.3. Determination for fundamental constant of N_2(A^3SIGMA^+_)The diffusion coefficient, the collisional quenching rate coefficient and reflection coefficient of N_2(A^3SIGMA^+_) are determined from the experiment in the Townsend discharge region. This project is now continued.4. Report of the investigation resultWe have reported three papers and contributed papers, respectivity. One of them is discussed about the loss process of metastable nitrogen molecule N_2(A^3SIGMA^+_). Two contributed papers were presented to ICPIG (1989 and-1991). One has contributed to GD92 (International conference on gas discharges and their applications). Further, two papers are reported to Trans. IEE of Japan.

1.产生激发粒子空间分布的确定用蒙特卡罗模拟方法确定了产生激发粒子的空间分布。将计算扩展到包含电子能量非平衡条件的区域。研究了Ne/Ar混合气体、Ne、Ar和N_2中的电子群行为。激发粒子的损失过程用解析方法研究了激发粒子的损失过程，它求解了N_2(A^3*^+_u)第三类边界条件下的扩散方程。从分析结果中，我们证实了激发态粒子在边界处的反射现象。N_2(A^3SIGMA^+_)基本常数的测定N_2(A^3SIGMA^+_)的扩散系数、碰撞猝灭速率系数和反射系数是由汤森放电区的实验确定的。这个项目现在继续进行。调查结果报告我们分别报告了三篇论文和投稿论文。其中之一讨论了亚稳氮分子N_2(A^3SIGMA^+_)的损失过程。向ICPIG提交了两篇投稿论文(1989年和-1991年)。其中一人为GD92(气体排放及其应用国际会议)做出了贡献。此外，向Trans报告了两篇论文。日本的IEE。
