【摘要】 双频激电是由中南大学何继善院士提出与实现的，无论是在理论和方法，还是在仪器的开发与实现上都获得了革命性的成功。本文将从双频道激电法原理与方法，观测方案及观测参数的定义，时间域与频率域的等效性以及方法的应用等几个方面说明双频道激电法的优点。进一步从有限单元法的理论角度探讨双频道激电法的数据处理问题之一——正演问题。主要研究以下三个方面的问题：区域离散化、变分问题的离散化、单元分析。最后结合先进的计算机技术和高级的编程语言尝试双频道激电法数据处理系统的设计，由于时间的关系本文仅以实用的二维情况为例，完整地设计出数据处理的多个模块，实现一些程序模块，为今后完善双频道激电法在数据处理系统方面奠定基础，以便在矿产普查，地下水，石油，和地下资源等地质任务中能够得到广泛的应用。更多还原

【Abstract】 The Dual Frequency Induced Polarization is put forward andrealized by academician He Jisan of Central South University. Whether intheory and method, or in the development and the realization of theinstrument, it has acquired revolutionary success. The thesis aims tointroduce the principle and method of the Dual Frequency InducedPolarization method, observation blueprint, the definition of observationparameter, prove equivalent of time domain and frequency domain, andthe application of the Dual Frequency Induced Polarization method, etc.,in order to demonstrate the excellence of the Dual Frequency InducedPolarization method. The thesis further discusses one of the problems ofthe data processing of the Dual Frequency Induced Polarization method-the forward problem. The thesis mainly studies the following threeaspects: the domains discrezation, the discretization of the VariationProblem and cells analysis. Finally it tries to design the system of dataprocessing of the Dual Frequency Induced Polarization method byadopting the advanced computer technology and the advancedprogramming language. Because of the time, the thesis only adopts thepractical two-dimension as an example, systematically designs somemodules of data processing and realizes some modules of program. Itgives a good foundation for the future studies of the Dual FrequencyInduced Polarization method in the system of data processing and in order to gain extensive application in geological tasks, such as the search of mineral resources, groundwater, petroleum and underground wealth, etc.更多还原
