摘要
Break points or negative values often appear in the data of charging rate during the performance of the multi-electrode induced 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-point slurring filtering is conducted to reduce random interference effectively.
