迭加速度,即由最好的共反射点地震记录剖面得到的那些速度,不仅取决于反射层、等速界面的倾角及其不连续性,而且在很大的程度上取决于其曲率。一些例子说明了这种影响。介绍了一个校正这些影响的近似公式。一个理论上的例子表示出如何从迭加速度的时间剖面显示上恢复出真层速度。 The rate of superposition, that is, the velocities obtained by the best common-reflection point seismograms depends not only on the reflection layer, the dip angle of the constant velocity interface and its discontinuities, but also on the curvature to a large extent. Some examples illustrate this effect. An approximate formula for correcting these effects is presented. A theoretical example shows how to recover the true layer velocity from the superimposed temporal profile display.
