摘要
首先介绍了罗兰格研究员关于地震前兆信息量的研究思想，他在系统地分析了地震前兆信息量所应具备的一些基本特征基础上，将这些特征进行高度概括并加以抽象化，给出了地震前兆信息量综合数学表达式。经我们对实际地震观测资料进行计算，表明该表达式不仅可将各种地震观测资料的持续异常变化统一地转化为地震前兆信息量，而且还能定量地描述异常结束后其前兆信息的延续性，从而使地震异常所展示的前兆信息更加清晰化、直观化、完整化。这就为我们进一步探讨地震异常群体前兆信息时、空演变规律。
This paper stated Professor Luo Lange's research idea about the information magnitude of earth quake precursors.On the basis of analysing some basic characteristics possessed by the information magnitude of eatthquake precursors in a systematic way,he made these characteristics to be highly summarized and abstracted,and gave out the synthetic mathematics expression of information magnitude of earthquake precursors.Through calculating for the real earthquake observational data,it showed that not only can this expression unitedly transfer the lasting anomalous variations of various earthquake observational data into the information magnitude of earthquake precursors,but it can also describe precursory information continuity possessed by the anomalies which are termination in a quantitative way.Thus,the precursory informations shown by earthquake anomalies are made much more clear,audio-visual and complete.This has established the foundations for us to further more explore evolutionary regularity in time and space of colony precrusory in formations of earthquake anomalies and effectively develop the study of earthquake synthetic prediction.
