| 摘 要： | 利用多道光学分析仪测量Hα线形分布,从线形的分布推出再循环的氢原子主要来源于离子中性化后的反射和氢分子的离解。通过双高斯拟合Hα线形分布,由多普勒频移得出了氢原子的入射速度。从氢原子能量分布上的特征峰得出氢分子的离解方式主要是电离和直接离解。

| Abstract: | The distribution of Hα line shape has been derived with Optical Multichannel Analysis (OSMA).That shows that recycling hydrogen atoms stem from the reflection of ion neutralized and the dissocciatin of hydrogen molecular.The incent velocity of hydrogen atoms have been obtained from Doppler shift with double Gaussian fitting.The peak on the energy distribution of hydrogen atoms shows that the way of hydrogen molecular dissociation are direct and ionic disdissociation. |

| Keywords: | Plasma Line shape of optical emission Gaussian fitting |
