摘要
在对近区场积分表达式中各积分因子特性分析的基础上，提出了一种解决近区场含两个Ｂｅｓｓｅｌ函数奇异积分的分段Ｓｉｍｐｓｏｎ积分法，较好地处理了近区视电阻率的数值计算问题。
On the basis of analysing the characteristics of each integral factor in near source field expressions,a new piecewise Simpson integration for improper integral composed of double Bessel functions was advanced, and the problem of numerical calculation for apparent resistivity in near field zone was fairly solved.
