摘要
用有限元法进行电导率分块连续变化的二维大地电磁的模拟。本文第一部分给出有限元法系数矩阵的计算公式，可用于编制有限元法的计算程序。模型上的计算结果和计算精度的分析将在本文的第二部分介绍。
The finite element method is used for modeling 2-D MT field on a geoelectrical model with continuous variation of conductivity within each block. In the first part of this paper,the calculating formulae of coefficient matrixes in the FEM are given, which can be used for programming. The results of calculation for some 2-D models and the analysis of accuracy of calculation are discussed in the second part of this paper.
