当前,在对地震信息还没有一个清晰地识别判定的情况下,地震预报是一件难事,一般传统数学计算方法都将感到困难。本文就利用模糊方法识别地震前兆问题作一些初步讨论。模糊集合的特性是以“亦此亦彼”的原则来确定研究对象与集合从属关系。一个模糊概念虽没有明确的外延,但只要指定U中各个元素对它的符合程度,这个模糊概念也就得到一 At present, in the absence of a clear identification of the seismic information, earthquake prediction is a difficult task and the traditional methods of mathematical calculation will be difficult. In this paper, some preliminary discussions are made on the use of fuzzy methods to identify seismic precursors. The characteristic of fuzzy set is to determine the research object and the set subordination by the principle of “also correct”. Although a fuzzy concept does not have a clear extension, but as long as the specified elements in U meet it, the fuzzy concept will get a
