一次较成功的中期地震概率预测实例

１９８８年底依据地震活动性资料，运用ＭＹＣＩＮ不精确推理方法，提出了１９８９年及稍长时间的中国大陆中期地震趋势预测概率图，这是一次较成功的中期地震概率预测实例。     

前兆台站及观测测项的密度改正方法

介绍了使用MYCIN不精确推理模型生成发震可信度分布图、 可信度密度等值线图以及进行前兆测项的密度改正方法。 通过对1989年大同6.1级和1998年张北6.2级地震的震前异常进行推理和比较, 经过密度改正的可信度密度等值线图可以克服某些地区由于前兆测项密度较高而造成对地点判断的偏差, 从而对未来发震地区的判断起到较好的效果。     

MYCIN不精确推理的应用问题

本文论述了ＭＹＣＩＮ不精确推理在理论上所存在的问题，并结合与地震预报有关的实践进行了讨论。指出只要我们在应用中注意到ＭＹＣＩＮ模型可能出现的错误，那末在地震预报中应用这一不精确推理还是可行的。     

The research of a comprehensive program for earthquake prediction with seismological methods

In this paper, the MYCIN inexact inference method in Expert System is applied to comprehensive earthquake prediction. And it is proposed that the methods of determining various certainty factors, correcting correlation between anomalous evidences and computing comprehensive certainty factor of occurrence of some moderate or strong earthquake. By use of these methods, 18 earthquake cases since 1966 in North China is tested with seismological anomalies in different seismogenic stage, and the comprehensive certainty factors of occurrence of some moderate or strong earthquake are computed. At last some problems in application are discussed. The Chinese version of this paper appeared in the Chinese edition ofActa Seismologica Sinica,13, 328–337, 1991.
