本代码用于进行重磁复杂型体正演计算，模型可以包含多个异常体模型，起伏地形。用于计算的相关数据文件一并附上，产生的*.GRD文件为网格文件，建议用surfer绘制-The code for the complex body of gravity and magnetic forward calculation model can contain multiple abnormal body model, undulating terrain. Used to calculate the data file attach generated*. GRD file for grid files, it is recommended to use surfer draw
