雷电虽然是一种常见的自然现象,但它的科学知识和对建筑物、森林、堆垛及人身的危害,往往不被非专业人员所重视。我认为雷击和火灾有同等重要的意义。由于雷电压可达30至40万伏,雷电流可达20至30万安,因此对建筑物的损坏和对国民经济的损失是相当严重的。这次大兴安岭森林大火,虽然是因野外吸烟和违反操作规程所造成的,但以往一些林火也有雷击引起的。据我1954年至1986年调查的北京地区121次雷击事故分析,因雷电引起火灾的

The Great Hinggan Mountains forest fire, although it is due to field smoking and violation of rules and regulations caused, but in the past some fire caused by lightning. According to my investigation from 1954 to 1986, 121 lightning accidents in Beijing were analyzed and the fire caused by thunder and lightning
