防雷技术中的两个理论问题的研究

ON TWO PROBLEMS IN THE TECHNIQUE OF LIGHTING PROTECTION

从物理学角度对当前防雷技术中争论较大的两个理论问题进行了分析，这两个问题是：目前市场上流行的防雷产品“消雷器”能否有效的消雷；防雷技术的接地电阻测量中的物理问题，文章对以上问题的一些错误的观点及防雷技术中的错误予以澄清，以期对我国的防雷工作能有所帮助。

From the viewpoint of physics, two theoretical problems in nowadays technique of lighting protection are argued, namely if the lighting protector sold at present time on the market is effective and how to measure and what is the norm of resistance in earthing wire for lighting protection. It is valuable to clean up some uncorrect point of view in the lighting protection.
