摘要
以实验结果为依据,分析了二次电位和二次电场的时间谱随测点位置和供电电流强度以及供电时间的改变而变化的若干规律.讨论了二次电位和二次电场出现异常谱的原因,并分析了极化球体上U_2、E_2的表达式,提出了存在的问题及其严密、精确解的表达式.
On the basis of experimental results, some variation regularities of the time spectrum of secondary potential and secondary electric field varying with the location of station, exciting current intensity and current-on-time are analysed. The origin of IP anomaly spectrum is discussed. In addition,after analysis of the expressions of U_2 and E_2 for a polarizable spherical body, the authors put forward a strict and exact solution.
