| 摘 要： | 本文提出了利用复射线束相位匹配原理合成地震图方法--复相位匹配方法。该方法系利用相位匹配原理把复数域中波传播方程的解和界面联系起来得到的,可解决具有任意形状、光滑曲面界面的层状均匀弹性空间波场计算问题,克服了广义射线法应用于这个问题所遇到的困难。

| Abstract: | A new method for synthetic seismograms is given in this paper, which is obtained by using phase matching principle to connect the solutions of wave propagation equations in complex domain with interfaces. This method solves mainly the problem of calculating the wave-field over stratified homogeneous media with arbitrarily shapped, smooth, curved interfaces, and overcomes the difficulty that the generalized ray method encounters when applied to the problem. |
