高密度激发极化法在野外测量中,其充电率数据经常会出现突变点和负值,给解释工作带来了很大的困难.通过分析充电率数据出现突变点和负值的原因,选择三次样条插值法对数据进行插值处理,最后通过三点圆滑滤波,压制了随机干扰,突出有用异常.

Break points or negative values often appear in the data of charging rate during the performance of the multi-electrode in-duced polarization method in the field, which causes great difficulty in data interpretation. Based on an analysis of the causes of break points and negative values, this paper gives prominence to the useful anomaly by using interpolation of cubic spline to process the data. Three-points slurring filtering is conducted to reduce random interference effectively.
