| 摘 要： | 利用无狭缝摄谱仪获得闪电回击过程的光谱,依据Hα线的Stark谱加宽计算了闪电通道的电子密度,同时由Saha方程,通过半经验的方法也获得了通道的电子密度,并对两种方法得到的结果进行了比较、分析;讨论了电子密度与闪电放电特性之间的相关性。为闪电光谱进一步的定量分析,尤其是对闪电放电通道的导电特性、辐射特性及通道结构的研究和有关的理论计算提供了参考数据。 |

| Abstract: | Lightning spectra is obtained by Slit-less Spectrograph. According to Ha line Stark broadening formula, electron density is calculated. Simultaneously, with Saha equation, the electron density is also obtained by the semiempirical method. Comparing with the results obtained by two different methods, the connection between the electron density and the characteristic of lighting is discussed. The results provide reference data for further lightning spectra quantitative analysis, especially for the conductivity,radiation characteristic of lightning discharge channel and the structure of channel. |
| Keywords: | Electron density Stark broadening |
