摘要
首先,借鉴n值?ukasiewicz逻辑系统中公式的赋值及赋值顺序,给出了公式的向量表示形式;接着,利用公式的赋值及赋值顺序给出了公式的真度、两公式间的3种相似度与伪距离的定义;最后,讨论了公式的真度和公式间的3种相似度与伪距离所具有的一些良好性质。
The vector representation form of formula was given first based on the assignment and assignment order of formula in n-valued ?ukasiewicz propositional logic system.Then,using assignment and assignment order of formula,the truth degree of formula and the definition of three kinds of similarity degree and pseudo-metric between two formulas were also introduced.Finally,some good properties of truth degree,similarity degree and pseudo-metric between formulas were discussed in detail.
