| 摘 要： | 利用参考速度进行波动方程的坐标变换和玻恩近似,建立了把散射势与速度扰动项相联系的积分方程,通过求解振动项,获得了层速度与界面的反演结果。文中所用的合成记录反演结果表明了本方法运算速度快、精度高,前提条件少。

| Abstract: | There arc already a lot of papers dealing with seismic wave inversion from abroad, however, those with good invcrson results arc still rare. This paper makes use of refferential velocity transformation and Born - approximation to establish integrate cqation linking scattering potentials and the velocity disturbations. By solving the vclocily disturbing term, we obtain locations. The inversion example used with synthesized scismograrn shows that this method has the advantages of fast calculation, high precision and few rcsumblcd condition. |
