摘　　要：基于条件概率的思想,在连续值命题逻辑系统中引入赋值密度函数概念,给出了公式的概率真度、条件概率真度的定义,定义了公式间的相似度和伪距离并证明了概率真度的推理规则。In this paper, the valuation density function of formulas in the continuous value propositional logic system is proposed on the idea of conditional probability. The definition of probability truth degree and conditional probability truth degree for formulas in the continuous value propositional logic system is proposed. The similarity degree and pseudo-distance between formulas was also defined, inferential rules of probability truth degree was proved.
