摘要： 利用模糊数学中异常从属函数方法对1990~1997年华东地区 16种前兆观测方法,近5万组观测数据的综合前兆场进行了时空演化特征研究。结果表明,异常从属函数μ对发生在华东地区的Ms≥5.0地震有较好的映震能力,可作为中期、中短期预报的综合指标,对地震三要素可作出较为准确的判定。

Abstract: This paper studied the space-time evolution characteristics of East China with the method of improper slave function in fuzzy mathematics, which studied 50000 sets of com prehensive precursor field data observed by six teen methods of precursory observation. Through the study, we can conclude that improper slave function shows fairly good earthquake-reflecting capacity to earthquakes with Ms 5. 0 in eastern China, Which can be regarded as comprehensive parameter to the medium-term and short-term earthquake prediction and can determine three elements of an earthquake mo re exactly.

Key words: Precursor field, Slave function, Eastern China region
