| 英文摘要 | It is very important to study the solution reliability of nonlinear inversion problem when we reconstruct the seismic velocities and Q value images. In order to discuss the algorithms stability and inversion results to ART (Algebraic Reconstruction Technique), SVD (Singular Value Decomposition) and LSQR (Least Square QR), this paper deals with quite illconditioned problems by using the three algorithms. According to the numerical computation results, the relative errors and stability appraisals for the three methods were given under the above conditions. Further, velocity images to a geological model were compared based on the three algorithms, which provide a quantitative parameters for the analysis of results of seismic tomograph. |
