说明：  地表起伏地形在野外矿产资源勘察中不可避免，其对直流电阻率法勘探影响巨大．近年来，电阻率三维正演 取得诸多进展，特别是应用非结构网格我们能够进行任意复杂地形和几何模型的电阻率三维数值模拟，但面向实 际应用的起伏地形下电阻率三维反演依然困难．本文基于非结构化四面体网格，并考虑到应用ＧＰＳ／ＧＮＳＳ时，区 域地球物理调查中可非规则布设测网的实际特点，实现了任意地形（平坦或起伏）条件下、任意布设的偶极偶极视 电阻率数据的不完全ＧａｕｓｓＮｅｗｔｏｎ三维反演．合成数据的反演结果表明了方法的有效性，可应用于复杂野外环境 下的三维电法勘探．
(Undulating surface topography in the field of mineral resources exploration inevitable, its exploration of the great DC resistivity method affected. In recent years, three-dimensional resistivity forward We made a lot of progress, especially the application of unstructured grid that we can carry out the three-dimensional resistivity any complex terrain and geometry simulation, but the real face Three-dimensional resistivity inversion remains difficult international application under the undulating terrain. Based on unstructured tetrahedral grids, and taking into account the application of GPS/GNSS, the zone Non-domain geophysical surveys can measure the actual characteristics of the rules laid network, to achieve any terrain (flat or undulating) conditions, arbitrary laid  dipole-dipole depends Resistivity data incomplete GaussNewton D inversion. Synthetic data inversion results show the effectiveness of the method can be applied to a complex field environment Under the three-di)
