摘要
目前国内外都在研究试验多层密度界面的重力反演。本文详细介绍了基于场变换原理的分离场法;重新推导了与安东诺夫相近的换算系数;设计了迭代反演方法;并根据理论模型和实例的试算,探讨了方法的误差来源和应用条件,在二维多层密度界面的反演中进行了有益的尝试。
Abstract
At present, the research of gravitational inversion of multi-density interfaces are just in progress both at home and abroad. In this paper, the technique of separating the fields by field transformation was detailed, the conversion factors which are the like of that calculated by AHTOHOB IO.B., were rederived, the process for iterative inversion was worked out, the origins of error and the qualifications for its employment were probed into on the basis of theoretical model as well as the trial and error procedure. Significant attempts for inversions of 2-D multidensity interfaces were brought about.
