多回击闪电放电通道的温度特性及其与电学特性的相关性分析 利用在西藏那曲地区由无狭缝光栅摄谱仪得到的3个分辨比较清晰的多回击自然闪电过程的光谱，研究了放电通道的温度及其变化。证实：闪电不同回击过程的通道温度有明显差异，闪电前期的通道温度通常较高，之后呈逐渐降低趋势。首次将光谱分析与同步的电学资料对比分析，讨论了电流的热效应与通道温度的相关性，并推断通道温度与回击过程传输的能量呈正相关。 The Correlative Analysis Of Characteristic Between Temperature and Electrical for CG Lightning Discharge Channel With Multiple Return Strok The spectrum from Three Multiple return stroke of CG lightning flashes have been clearly obtained using a slit-less spectrograph in Nagqu, Tibet plateau. The temperature and changes in discharge channel was Studied in this paper and We Confirm that there exists remarkable difference in channel temperature in different return stroke. Channel temperature is higher during the lightning earlier stage, Was gradually decreased after the, We make a comparative analysis between Spectroanalysis and synchronization of the electrical data in the first time, Discussed the relevance between thermal effect of current and channel temperature and inferred the transmission of energy in return storke was positive correlation with channel temperature .
