【Abstract】 A simplified formula of gravity and magnetic anomalies of 2 5D polygonal prism is presented and some concrete methods and techniques about visualized modeling, modification, real time forward and inversion are introduced. With this graphical system which is convenient and powerful to use, one can combine kinds of geological information to guide and control the procedure of inversion, and make his thinking and technical plan reflect fully. So, the speed and quality of calculation will be raised highly.更多还原
