| 摘 要： | 以一次闪电回击过程的光谱为例,采用二谱线法和多谱线法对通道温度进行了计算.对比所得数据发现,多谱线法可以部分地消除二谱线法中因所选谱线组不同而引起的计算结果在一定程度上的不确定性.因此,在利用谱线相对强度进行闪电通道温度研究时,运用多谱线法是最佳的选择.

| Abstract: | As an example,a slit-less spectrum for first return stroke of lightning between the cloud and ground has been chosen.According to the relative intensities of lines and transition parameters,temperature in lightning discharge channel is calculated by using multiple-line and double-line method.Compare these data obtained by the two methods,it is found that using multiple-line method canminimize error resulting from choosing different lines in double-line method.So the result shows that multiple-line method is better than double-line method in studying temperature in lightning return stroke channel. |
