1.产生的激发粒子的空间分布的确定产生的激发粒子的空间分布是使用Monte Carlo模拟方法确定的。将计算推广到包括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.激发态粒子的损失过程用解析方法研究了N_2（A^3*^+_u）在第三类边界条件下的扩散方程。根据分析结果，我们证实了激发态粒子在边界的反射现象. N_2（A^3 SIGMA ^+_）基本常数的测定通过实验测定了汤森放电区N_2（A^3 SIGMA ^+_）的扩散系数、碰撞猝灭速率系数和反射系数。该项目目前仍在继续。调查结果报告我们分别报道了三篇论文和贡献论文。其中之一是讨论亚稳氮分子N_2（A^3SIGMA^+_）的损失过程。向ICPIG提交了两份论文（1989年和1991年）。其中一人对GD 92（气体放电及其应用国际会议）做出了贡献。此外，还向日本国际电子工程师学会报告了两篇论文。

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.
