一、前言我国多年来开展地震预报的事实证明地震前确实存在一些信息,但并不唯一,它有时能反应地震,有时不能反应,即在前兆一地震这一系统中既含有已知信息,又含有非确知的信息,因而它是一个灰色的系统。目前地震综合预报的过程,实际上是对前兆信息进行归纳的过程。这种归纳可以从地震孕育机理方面入手,但更多的是采用经验
I. Preface The fact that earthquake prediction has been carried out for many years in our country proves that there is indeed some information before the earthquake, but it is not unique. It can sometimes respond to earthquakes and sometimes can not react. That is, in the system of precursory-earthquake, it contains both known information and Contains non-deterministic information, so it’s a gray system. At present, the process of comprehensive earthquake prediction is actually a process of summarizing precursor information. This induction can start from the earthquake breeding mechanism, but more is the use of experience
