摘要： 利用无狭缝摄谱技术获取中国广东人工触发闪电通道等离子体的光谱.通过光谱分析确定通道等离子体的主要成分为N II、O II、Fe II离子,以及中性N I和O I原子.根据激光诱导击穿光谱技术(LIBS)获取N II离子和Fe II离子的丰度为68.4%和3.6%.基于原子离子的Saha电离平衡方程以及大气中氮氧气体的浓度比,测定了触发闪电通道等离子体中N I、O I、O II的丰度为4.4%,6.0%,17.6%.测量结果与其他实验符合较好.

Abstract: The spectrum of artificially triggered lightning channel plasma in Guangdong, China was obtained using slit free spectroscopy technology. The main components of the channel plasma were determined to be N II, O II, Fe II ions, neutral N I, and O I atoms through spectral analysis. Based on laser-induced breakdown spectroscopy (LIBS), the abundances of N II ions and Fe II ions were obtained by 68.4% and 3.6%, respectively. On this basis, based on the Saha ionization equilibrium equation of atoms and ions together with the concentration ratio of nitrogen and oxygen gases in the atmosphere, the abundances of N I, O I, and O II in the triggered lightning channel plasma were determined to be 4.4%, 6.0%, and 17.6%. The current measurement results are in good agreement with other experiments.

Key words: channel plasma of artificially triggered lightning, laser induced breakdown spectroscopy technology(LIBS), abundance of atoms and ions, electronic temperature, electron density
