在地震预报中,地震工作者所预报的震级实质上是一个宽度很大的模糊数,而不是精确的震级,因此本文以小震、中震、大震、特大震四种类型来代替精确的震级预测.另外,从Fuzzy数学的角度来看,地震三要素与前兆因子之间的关系不是某种具有一定误差分布的线性关系,而是一种Fuxxy关系,即多种前兆因子合成结果与要素的模糊映射关系.本文将地震预报看作是一个复杂系统中输出入之间的一个Fuzzy映射,即前兆因子通过Fuzzy关系的一种Fuzzy变换.
In earthquake prediction, the magnitude predicted by earthquake workers is essentially a fuzzy number with a wide width, rather than an accurate magnitude. Therefore, this paper replaces the four types of small earthquakes, medium earthquakes, large earthquakes and special earthquakes, In addition, from the point of view of Fuzzy mathematics, the relationship between the three elements of the earthquake and the precursors is not a linear relationship with a certain error distribution, but a Fuxxy relationship, that is, the result of the combination of the precursory factors and the factors This paper considers the earthquake prediction as a fuzzy mapping between the inputs and outputs of a complex system, that is, a fuzzy transformation of the precursor factor through the fuzzy relation.
