| 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ｕ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 studied50 0 0 0 sets of comprehensive precursor field data observed by sixteen 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 more exactly. |
