本程序在目前日本流行的电阻率／激发极化法二维反演程序［４］基础上，将电导率和极化率分块均匀变为分块连续变化，并在目标函数中加入了更多的先验信息，使反演结果的唯一性和真实性大大增加。在有限元正演模拟中，又采用三角单元剖分，使实测数据在反演以前不需要进行地形改正。本文介绍了该方法的基本原理和程序的使用方法，并给出了几个理论算例和野外实例
Based on the popular 2D resistivity / excitation polarization inversion program in Japan [4], the program uniformly changes the conductivity and the polarizability into continuous blocks and adds more functions to the objective function Multi-priori information makes the uniqueness and authenticity of the inversion results greatly increased. In the finite element forward modeling, the triangulation unit is adopted to make the measured data do not need terrain correction before inversion. This article introduces the basic principles of the method and the use of the program, and gives a few theoretical examples and field examples
