摘要
基于探测器探测目标的多样性，从静电场出发，对极间电位移和电场强度特性进行了研究，进而分析了极问电容变化的本质并进行仿真。仿真结果表明目标切割电力线长度和目标相对电容率是影响极间电容变化的两个重要目标参数，目标切割电力线越长，极间电容变化越大；目标相对电容率对极间电容变化的影响很小，与Marconi公司实测的电容探测器炸高散布小的结论一致。
The character of electric displacement and field intensity was studied from the electrostatic field for the various targets. Further the essence of the capacitance change was analyzed. Also simulations were made which showed that target length of cutting electric-power line and target dielectric constant were two corresponding target parameters to the capacitance change. The longer the length of cutting electric-power line was, the more the capacitance changed. The target dielectric constant did little work to the capacitance change which was consistent with Marconi＇s conclusion that the burst height dispersal was small.
