| 英文摘要 | Seismic anisotropy exists extensively in the earth, wherea the TI medium is the most common anisotropic one. The conventional finite difference modeling (FDFDM) of 2D VTI media frequency-space domain with 9-point scheme can cause serious numerical dispersion because of its poor computational accuracy. The average-derivative optimal method (ADM) not only is suitable for equal and unequal directional sampling intervals, but also retains high precision. We introduce this idea into the qP wave equation of 2D VTI media to improve the computational accuracy. |
