摘　　要：采用对比性的试验，对放电击中点分布的影响因素进行了试验研究。结果表明，放电击中点的概率分布与上电极对各目的物的击穿电压、击穿时间和迎面放电的发展有关，受目的物几何形状、接地电阻和几何台距等因素的影响。所得结果深化了对雷击击中点选择物理过程的认识。Various factors affecting probability distributionof discharge striking points were studied by contrast experiments. The results shows that the probability distributionof discharge striking points is related to the breakdown voltage, breakdown time and the development of head-on discharge, it is influenced by geometric shape of object,ground resistance, and geometric striking distance. Thestudy deepens the knowledge of the physical process of theselection of lightning sincing points.
