摘要
DivSummary name="EnDivSummary">In order to obtain details of inversion results,an inversion method based on partial derivative and statistics for VES is proposed.The advantage of this method is that the initial model for inversion is similar to the actual target,and there is no need to calculate large linear equations,so the calculation amount is much lower.The total fit error and the local fit error caused by anomalies are separately calculated during the inversion to direct the variation.The inversion result is visual.Theoretical model and real data experimental tests demonstrate the effectiveness of the method.
