中文摘要：

依据闪电光谱信息，分别用多谱线法和saha方程计算了闪电放电等离子体的电子温度，通过对结果的比较分析，探讨了诊断闪电放电等离子体温度的方法．结果表明，闪电回击通道温度一般在2×10^4～3×10^4；在放电峰值电流阶段或光谱中NII谱线比较丰富时，多谱线法计算得到的结果比较可靠；在拍到谱线较少时．依据一条谱线的加宽，用Saha方程得到的温度值略大于多谱线法计算的结果，且采用不同谱线计算的结果差别不大．

英文摘要：

Based on the information of lightning spectra, the electron temperature of lightning discharge plasma are calculated by using multiple-line method and Saha equation, respectively. The methods for diagnosing temperature of lightning discharge plasma are discussed through a comparative analysis of the results. The results show that temperature of lightning return stroke is usually about 2×10^4～3×10^ K. The results from multiple-line method are more reliable in the discharge peak current stage or when ＊h,, spectral lines of NII are rich. The temperature obtained from Saha equation are slightly greater than that by using multiple-line method, and there are little difference between the results of different spectral lines.
