In chapter 2, to meet the application requirements of incomplete information system, based on propositional connectives ∧、∨、→、ヲ、～ and ～, we construct medium logic propositional calculus system MP〓 and medium logic predicate calculus system MF〓.

第一章：简要说明不完全信息数据库和模糊数据库研究的目的和意义，介绍中介逻辑和模糊数据库的发展、模糊数据库系统的特性以及本文的主要研究工作。

We study the properties of $BR_0$-algebra and the total complication triple I method on complete $BR_0$-algebra, and we apply the results to $R_0$-Unite interval $\overline{W}$. Not only we have simplified the proof of the results of $R_0$-type triple I method on $R_0$-Unite interval $\overline{W}$, but also we make the proof to combine with the formal deductive system for fuzzy propositional calculus. This work also explains that the $R_0$-type triple I method is a matching fuzzy inference with $B{\cal L}^*$ system.

研究了基础$BR_0$-代数的性质和基于完备基础$BR_0$-代数的全蕴涵三I算法，对一般蕴涵算子给出了三I算法解存在的一个充分条件，并将结果应用于$R_0$-单位区间$\overline{W}$，不但极大的简化了$R_0$-单位区间$\overline{W}$的$R_0$-型$\alpha$-三I算法结果的证明，而且使其证明过程与相应的模糊命题演算系统结合起来，说明了$R_0$-型三I算法是与$B{\cal L}^*$系统相匹配的模糊推理方法。

The model for deductive theory is the propositional calculus.

演绎推理理论的模型是命题演算。

By using the model of this interpretation, the reliability theorem and the uniformity theorem are proved of the propositional calculus plus syllogistic system.

本文最主要的工作是建立了三段论的一种解释，并且在这种解释模型中，证明了命题演算+三段论系统的可靠性定理，一致性定理，还从语义角度，对项的周延性等问题发表了一些意见。

This paper proves that it is impossible for all the theorems in classical propositional calculus to be tautologies in the field of fuzzy propositional calculus, then a quasi formal deductive system is established for fuzzy propositional calculus based on a kind of type algebra.

引入了一种代数，称为模糊公式代数。在这种代数上建立了一个准形式演绎系统，证明了相应的可靠性定理与相容性定理，提出了程度化的ModusPonens规则和HypotheticalSylogism规则

In 1879, the publication of ""Concept Writing"" marks the foundation of propositional calculus and the predicate calculus —— the basic part of mathematical logic.

So-called first-order theorem proving may be restricted to a propositional calculus with terms (constants, function names, and free variables) added, making it impossible to express mathematical induction.

所谓一阶定理证明可限于命题演算的条款（常数，函数名，并免费变量）说，无法表达数学归纳法。

As most of the present decision methods of propositional formulas are based on semantics and cannot give an important reference in many reasoning applications, namely deduction procedure, a deduction-based decision method that can give the deduction procedure during the decision procedure is presented based on the propositional calculus system L.

目前命题公式的判定方法大都是基于语义的，不能给出演绎过程，而演绎过程是许多推理性应用的重要依据。
