NUMERICAL CALCULATION METHODS OF WIDE FIELD APPARENT RESISTIVITY
摘要
Abstract
Wide field apparent resistivity is superior to cagniard apparent resistivity in reflecting transformation rules of the homogeneous underground media, and we usually can acquire the value of wide field electromagnetic method by iterative algorithm and inverse interpolation algorithm. In order to compare the two methods, we have done some computation research. By the large calculating work to prove the results from both methods could correctly reflect transformation rules of the inhomogeneous underground media. The process of inverse interpolation algorithm is steady without too much constraint conditions, however, the iterative algorithm do not need the precondition that the objective function must be monotonic, and it has simple operation, but the algorithm maybe divergent. So the suggestion is that we should choose the calculation method by the characteristics the function has.关键词
