模糊信息检索方法是通过统计数据来确定从属函数,然后根据从属函数矩阵对样本进行分类,从而判断出地震活动的不同类型,并对未来的地震活动性作出预报。 文中以我国南北地震带银川——松潘段的中强震活动为例,对这种方法进行了初步检验,发现效果较好。
Fuzzy information retrieval method is to determine subordinate function through statistical data, and then classify samples according to subordinate function matrix to judge different types of seismic activity and predict future seismicity. Taking the moderate-strong earthquakes in Yinchuan-Songpan section of the North-South Seismic Belt in China as an example, this method is preliminary tested and found to be effective.
