摘　　要：利用多道光学分析仪（ＯＳＭＡ）测出了ＨＴ－６Ｍ托卡马克限制器前Ｈα谱线型分布，并从线型分布得到中性氢原子能量分布，分析了发生在边界的原子、分子过程。通过拟合Ｈα谱线型分布的远翼，由多普勒展宽求出等离子体离子温度。The distribution of H α spectral lineshape has been derived from the surface of limiter in HT 6M torkamak, with Optical System Multichannel Analysis. The energy distribution of hydrogen atoms has been directly derived from the distribution of H α lineshape, Main molecular processes at plasma edge have been discussed.Plasma ion temperature has been obtained from fitting remote wing of the distribution of H α lineshape with Gaussian function.
