首先在Godeln值命题逻辑系统中添加了新的连接词Δ,~,给出了Godeln值命题逻辑系统中命题公式间的真度、相似度和伪距离的定义;讨论了在该系统下它们的一些相关性质,并给出了相应的证明。
The new connectorsΔand~are presented in G?del n-valued propositional logic system in this paper,the definition of truth degree,similarity degree and pseudo-metric among formulas are given in G?del n-valued propositional logic system,some related properties of them among formulas are discussed under the system,and the corresponding certificate is presented.
