摘　　要：基于各向异性大地频率域电磁测深的正演计算,研究了二层大地模型中水平电偶极源下各向异性参数对电场Ex分量的振幅和相位曲线的影响。计算出在不同各向异性系数下电场水平分量的振幅和相位值,通过对其曲线特征进行分析,总结出一些规律性的结论,对野外资料的解释有一定的指导意义。The paper deals with forward computation of frequency electromagnetic sounding on the anisotropy earth model. It studies the influence of anisotropy coefficient on amplitude and phase curve of the electric field Ex component with horizontal electric dipole source in case of the two--layer earth model. Some results are summarized through draw- ing the graph of curves and analyzing the characteristics, which will be helpful to the data interpretation of the field job.
