摘要
节电电位的求解在地球物理正反演中都有重要的作用。作为地球物理计算中常用的两种方法,数值解和解析解各有特点,以求节点电源场中垂直接触带地表节点电位为例,基于FORTRAN语言编写程序,分别用解析计算法和数值计算法进行求解,并对求解结果进行精度比较,以确定解析计算法的准确性和可用性,从而确定了一种效率更高的计算方法。
As the important calculation methods of the geophysics, the numerical solution and analysis solutions have different features. Taking the potential caused by vertical sheet in the point source current field domain for example, based on programming with FORTRAN, the result is analyzed by the use of the above-mention two methods respectively, and comparison on accuracy based on the result is made to determine precision and availability of the analysis solution. A more effective method will be determined.
