摘　　要：根据2009年山东人工触发闪电实验(SHATLE),对一次触发闪电的雷电流资料、近距离地面电场和高速摄像资料进行了分析,3种信号随时间的分布曲线具有较好的一致性。统计了3种信号中的所有脉冲信息并分析了这些脉冲的光电特征。该次人工触发闪电共包含31个脉冲,根据脉冲参数特点,将所有脉冲分为4类,并对这4类脉冲的电流、电场和光强参数分别进行了统计,总结了它们的光电特性和变化规律;另对该次闪电的特殊性进行了分析和讨论。The channel base current, the electrical field of close distance and the optical data of high-speed camera in a rocket-triggered lightning are analyzed base on the Shandong Artificial Triggering Lightning Experiment （SHATLE） in 2009. These three signals coincide with each other very well. All the pulses are counted and their electrical and optical characteristics arc summarized. This flash contains a total of 31 pulses and the pulses are classified as four kinds according to their features. The current, electrical field and luminosity parameters of the four kinds of pulses are investigated. Their electrical and optical characteristics are gained and the particularity of the flash is researched.
