摘要
用有限单元法进行电导率分层连续变化水平层的大地电磁正演计算，与解析法的计算结果进行对比，两者非常符合．算例表明，地表浅部岩层电导率的不均匀性对大地电磁测深曲线的高频段有较大影响．
In this paper,the finite element method is used to calculate MT field for the geoelectrical model with continuous change of conductivity in each horizontal layer.The results of calculation agree very well with those obtained by analytic method.The calculation shows that the inhomogeneity of resistivity near ground surface has a great influence on the high frequency section of sounding curve of MT.
