几何地震学的本来任务是研究物体的几何形态,也就是在地面上利用地震反射或折射的方法达到了解地下构造起伏、分布范围的目的。因此,早期的地震勘探工作,只是着眼于如何准确地记录反射波到达地面的时间,借此推算出所记录的反射波来自何处。但是,一张地震记录上所能表达的远非“时间”一个参数,因为地下不同的地质结构应该产生多种多样的信息内容。对于这些同时出现在地震记录上的许许多多的其他信息,
The original task of geometric seismology is to study the geometry of objects, that is, to use the method of seismic reflection or refraction on the ground to understand the purpose of fluctuating and distributing the underground structures. Therefore, the early seismic exploration work only focused on how to accurately record the arrival time of the reflected wave to reach the ground, so as to deduce where the recorded reflected wave came from. However, what can be expressed in a seismogram is far from being a parameter of “time,” because different underground geological structures should produce a variety of information contents. For many more of these other messages that appear on seismic records at the same time,
