剩磁法在雷灾事故分析中的应用

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。

Application of Residual Magnetic Method in the Lightning Accident Analysis

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.
