Abstract：Allowing for the current unclear mechanism of lightning damage,and failure to predict the location,time and extent of lightning strikes accurately,the natural lightning waveform is studied to analyze the phenomenon of pulse attenuation resonance and lightning damage in the subsequent return stroke.

Key words：lightning waveform;lightning flash;sample rate;lightning leader;subsequent return stroke;triggered lightning;pulsed magnet field;lightning damage

摘　要：针对当前雷电破坏机理尚不明确，不能精准预测雷电闪击地点、发生时间、危害程度的情况，通过对自然雷电波形的研究，分析雷电继后回击存在脉冲衰减谐振过程和雷电破坏的现象。
