摘　　要：在估计高空核爆炸后碎片衰变产生的电子在地磁场的通量分布中,由于碎片受磁力线的约束,沿场线形成一个碎片管,碎片管在辐射带内的扩散(径向运动)过程用磁壳参数L(偶极子场等同地心距R)的数值变化表征,所以不可避免的涉及L的计算,文中运用等效电路模型,以国外starfish高空核爆试验为依据,估算出L在前100秒内的变化,和国外的试验结果基本相近。When calculate the electrons distribution in the geomagnetic field after high altitude nuclear explosion , as the electrons are restrict by magnetic force and form a debris tube, it＇s motion can describe by the change of L, so the L calculation is the first step. this paper use the equivalent circuit model, base on the starfish nuclear explosion , calculate the L change of the first 100 second , and get a good result compare with the data of America.
