求得更接近真实的地球物理模型是地球物理工作的最终目的.地球物理学家近几十年来为此作了不懈的努力,其中包括改进和试制新的仪器设备以取得更精确、更完善的观测数据,以及研究更好的反演方法以求得最佳的地球物理模型.大地电磁测深法也不例外.在观测数据的点数和精度一定的情况下,如何获得更好的地球物理模型,就成了地球物理学家,特别是反演问题专家十分艰巨的任务.近十多年来,各种反演方法像雨后春笋拔地而起,层出不穷,在不同的约束或近似条件下,各种方法都取得了能拟合观测数据的特定模型.反演方法之众多,恰好从反面说明解的非唯一性的严重.因此,如何缩小和判断解的非唯一性,提高其可靠性,就成了当今反演问题专家的最为重大的课题.
Finding a more realistic geophysical model is the ultimate goal of geophysical work, and geophysicists have worked tirelessly in recent decades to improve and prototype new equipment to achieve more accurate and complete Observational data, and better inversion methods to obtain the best geophysical model.MEMS is no exception.How to obtain a better geophysical model under the certain point and accuracy of observed data? , Has become a very arduous task for geophysicists, especially inversion experts.In the past ten years, various inversion methods like springing up after springing up, emerging under different constraints or approximate conditions Many methods have been able to fit the observational data of a particular model.Many methods of inversion, just from the opposite side to explain the non-uniqueness of the solution.Therefore, how to reduce and determine the non-uniqueness of the solution, to improve its reliability, on It has become the most important issue for experts in inversion today.
