一个准模糊图拟阵的新特征

The New Character of Quasi-Fuzzy Graph Matroids

首先定义模糊拟阵的"元好"概念,并构造了具有"元好"性质的闭模糊拟阵模糊基的结构定理;然后,证明了闭模糊拟阵为准模糊图拟阵的充要条件就是"元好";最后,用"元好"概念,构建了准模糊图拟阵的又一个模糊基公理.

First,the concept of＂good-element＂in fuzzy matroids is defined in this paper,and the structure theorem of fuzzy bases in closed fuzzy matroids of good-element is constructed.Then,it is proved that＂good-element＂is the necessary and sufficient condition for a closed fuzzy matroid being aquasi-fuzzy graph matriod.Finally,with the help of the concept ＂good-element＂,another axiom of fuzzy bases is formed for quasi-fuzzy graph matroids.
