大地电磁一维正演，给定一个层状的导电的大地模型，在其上方进行不同频率的大地电磁测深测量，制作理论上应该得到的视电阻率观测曲线。-Forward one-dimensional magnetotelluric

将接地长导线源沿导线方向分解成多个电偶极子源，对若干电偶极子源产生的响应进行叠加得到接地长导线源的Hz响应。计算结果表明接地长导线源的Hz响应与电阻率之间的关系也为单值关系。-Decompose the grounded long wire source along the wire direction with several electric dipole, and overlay the response which produced by the electric dipole as t
