In the past, the inner integration of directive calculation coincide-loop TEM response was to find zeros in the integrating zone and then sum up all the values computed in the area between two neighboring zeros by normal numerical integration.
对于重叠回线装置的瞬变电磁法正演的内层积分,以往采用在积分区间内寻找贝塞尔函数的零点分布,依次在相邻零点之间采用一般的数值积分法在求得各自的积分值后再叠加的方法进行计算。
