摘　　要：本文从模拟试验、理论计算和现场实测结果得出的结论是：在雷云电场下，多针系统的电晕电流与避雷针的电晕电流没有本质的差别；到达云底的离子电流密度与实型针系统的形状无关，即由多针系统产生的到达云底的离子电流密度和由避雷针产生的到达云底的离子电流密度是一样的。From model test,theoretical investiga-tion and the results of field measurment under thethundercloud,the following conclusions are obtained:the magnitude of corona currents produced by chineselightning eliminator is of the same order as that pro-duced by lightning rod, when ion flow reaches thelower boundary of thundercloud, its density does notdepend on the form of lightning eliminator,j.e., theion flow density produced by chinese lightning elimina-tor is just the same as that produced by lightning rod.
