郭增建、秦保燕发现某些地震发生的时间间隔,比如强余震存在九天韵律,称之为“倍九法”。其实,时间间隔只具有极值信息,并不涉及极值之间的过程。当降低采样地震的震级,并结合地震发生地点,这类地震的迁移便具备过程信息。 Guo Zengjian, Qin Baoyan found that some earthquakes occurred at intervals, such as strong aftershocks nine-day rhythm, known as the “times nine law.” In fact, the time interval only has extreme information, does not involve the process between the extreme. When the magnitudes of sampled earthquakes are reduced and the occurrence of earthquakes occurs, the migration of such earthquakes provides process information.
