摘要
本文提出了一种地震折射液的虚拟射线理论,根据该理论,只要已知地表层的速度,即可直接由折射波信息提取地震参数,从而可实现折射界面的反演。 文中通过实际介质模型的计算机实验结果,验证了该理论的正确性。
In thispaper,a ghost ray theory of seismic refraction wave is presented. According to the theory ,if the near surface velocity is known,it is possible to obtain the seismic parameters from refraction wave signals directly,so that the inversion of refraction interfaces may be carried out. The correctness of the theory is proved by the result of experiments by means of real medium models through computers.
