| 英文摘要 | The advanced algorithms, such as reverse time migration (RTM) and full waveform inversion (FWI), require iterative calculation of the wave field. Its wave propagation part is highly sensitive to computational accuracy and stability. Therefore, how to find a way to obtain a finite-difference scheme that can consider the both aspects is absolutely critical. Here we propose a global optimized implicit staggered-grid finite-difference scheme that inherits the merit of high stability from the implicit finite-difference scheme and improves the computational efficiency remarkably. |
