避雷针电场与地面电场的相关性———E ≥ 1 ×103 E0。据此导出避雷针通过电晕放电可将地面场强控制于空
气击穿场强的0. 1%以下,从而为避雷针保护范围内被雷击中概率小于0. 1%的实际观测结果提供了理论解

around the top of lightning rod, the relativity between electric field of lightning rod and electric field of earth
surface is firstly arrived at - E≥1 ×103 E0. According to this equation, lightning rod through corona discharge can control electric in2
tensity of earth surface as under 0. 1 percent of air disrup tive field intensity, which p rovides theoretical exp lanation for that p robability,
whose scope which is p rotected by lightning rod is hit by thunder, is less than 0. 1 percent. This exp lanation broadens the human recog2
nition of the actingmechanism of lightning rod from the angle of electric field and intensity. |
