基于条件概率的思想,借助于各个逻辑系统中的演绎定理,在W3、G3、Π3、L3等三值逻辑系统中引入了条件真度的概念,并得到了条件真度的性质及相应的推理规则。
Firstly,the conditional truth degree of formulas in 3-valued Logic Systems W3、G3、Π3、L3 is proposed on the idea of conditional probability.Then the corresponding properties and inferential rule of Conditional Truth Degree are discussed.
