摘要: 在二值命题逻辑系统中,利用势为2的均匀概率测度空间的无穷乘积,通过计算理论[Γ]的全体模型占整个赋值空间的测度定义了理论[Γ]的真度,进而利用理论的真度简化了理论的发散度和相容度的计算公式,给出了由推理的前提集的真度估计其逻辑结论真度的表达式。

Abstract: By means of infinite product of uniformly distributed probability spaces of cardinal 2, this paper introduces the concept of truth degree of a logical theory [Γ]by computing the measure of all models of [Γ]in the valuation spaces. Simplified methods to compute the divergent degree and the consistent degree of a logical theory are given and the expression to estimate the truth degree of logical conclusions from the truth degree of its premise set is obtained.

Key words: quantitative logic, logical theory, truth degree of logical theory, consistency degree
