在雷击引发火灾的事故现场，因人为破坏或烧毁严重等因素，使得灾害发生原因的分析困难。采用金相法将金属的熔点等处的特征进行非量化的外观分析外．再利用剩磁法的测量数据以量化的形式作为雷击或其他起火的发生点和分析参考依据。本文将以系统的操作流程和典型实例，具体说明剩磁法在雷灾事故调查分析中的应用。
在雷擊引髮火災的事故現場，因人為破壞或燒燬嚴重等因素，使得災害髮生原因的分析睏難。採用金相法將金屬的鎔點等處的特徵進行非量化的外觀分析外．再利用剩磁法的測量數據以量化的形式作為雷擊或其他起火的髮生點和分析參攷依據。本文將以繫統的操作流程和典型實例，具體說明剩磁法在雷災事故調查分析中的應用。

In the field of fire accident aroused by lightning strikes, it＇s difficult to identify the reason of accident since of human damages or seriously burning out by fire. The metallographic method is used to conduct the nonquantified appearance analysis for the characteristics of metal materials＇ melting points, further, the measurement results provided by the residual magnetic method are taken as the quantified references for analyzing the lightning strikes and fire accidents. This paper demonstrates the application of the residual magnetic method in the investigations of lightning accidents by systematic operation procedure and typical instances.
