摘要 在时间域衰减成像的基础上 ,建立了一种与当前走时层析成像类似的衰减成像方法———逐次线性化衰减层析成像方法 ,这是一种基于射线理论的方法 .文中推导了逐次线性化过程的一系列公式 ,给出了相应的迭代算法及实现技术 ,并通过数值实验验证了方法的可行性 .作为走时层析成像的补充方法 ,实现多参数成像 .工程勘察实践表明 。 Based on the attenuation tomographical method in time domain, we propose a successive linearization method which is similar to the current travel-time tomographical methods. We deduce a series of successive linearization formulae and obtain the iterative arithmetic and the executable technique of the seismic attenuation tomography using the successive linearization method. The method feasibility is validated by numerical experiments. As a supplement, multi-parameters tomography is realized. We have applied the successive linearization method to engineer reconnaissance practice and gained preferable results.
