对确定核心期刊的载文量法、一次引文法、二次引文法进行了对比分析，它们都存在着明显的不足．用模糊数学方法通过计算机处理来确定核心期刊，我们引入了四个因素．运用模糊数学方法确定核心期刊既避免单一因素确定核心期刊产生的偏差，又解决了综合法没有考虑每个因素中的“量”的多少及没有判别每个因素对期刊质量影响的重要性的高低和影响程度的大小．
There are obvious deficiencies in determining the number of papers published in core journals, one citation method and two citation methods. Using fuzzy mathematics to determine core journals through computer processing, we introduced four factors. The fuzzy mathematics method is used to determine that the core journals not only avoid the single factor from determining the deviation of the core journals, but also solve the problem that the comprehensive method does not take into account the “quantity” of each factor and the importance of judging the influence of each factor on the journal quality And the extent of the impact of the size.
