摘要
将二值命题逻辑系统的真度概念引入到概率逻辑,定义了公式的期望,给出了反映公式之间内在联系的相关系数,研究了无限公式收敛时所遵循的规律及特点,引入了度量不确定性的特征值—熵。
The truth degree of classical propositional logic systems is introduced to probability logic,and the expectation of formula is given.Moreover,the correlation coefficient between formulas is studied;also the rules and the properties of infinite formula which is converging are studied.Finally,an entropy as the eigenvalue for metric uncertainty is defined.
