| 摘 要： | 利用“专家系统”的思想对澜沧－秋马Ms7．6和Ms7．2地震前每一前兆异常事件进行综合评估，以每一异常的最可能发震时间来计算发震概率，利用各类地震前兆异常群体信息熵研究了系统熵值与地震的关系。分析了1988年11月6日澜沧－耿马Ms7．6和Ms7．2地震前这种信息熵变化的特点。地震前，出现了明显的减熵有序变化。

| Abstract: | In this paper,each anomalous event before the Lanchang-Gengma earthquake is comprehensively estimated by using"seismic prediction exprert system".Probability of anomaly appearance is calculated by means of time that corresponds to the most likely time of earthquake occurrence for each anomaly.Considering the anomalous reliability,validity,significance and dependence,the authors use different weight to study the relation between comprehensive weighted information entropy of the seismic precursoris and earthquakes and analyse the information entropy variation before the Lanchang-Gengma M S 7.6 and 7.2 earthquakes on Nov.6,1988.It is shown that the variation of ordered decrease entropy appeared before the earthquekes. |
