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。

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。

The formal deductive systenm for Fuzzy propositional calculus, R0-algebras and BR0-algebras have been studied. The concepts of WBR0-algebras are proposed, the relationship between it and BR0-algebras has been investigated, the definition of basis BR0-algebras is simplified. Based on discussing the relationship between regular FI-algebras and regular residual lattice, the relationship between FI-algebras and basis R0-algebras has been investigated.

研究了王国俊教授建立的模糊命题演算的形式演绎系统L和与之在语义上相匹配的R0-代数以及吴洪博教授提出的基础R0-代数和基础L系统，提出了WBR0-代数的观点，讨论了它与BR0-代数的关系，简化了BR0-代数的定义，在讨论正则FI-代数与正则剩余格之间关系的基础上，讨论了BR0-代数与FI-代数的相互关系。

We study the properties of BR0-algebra and the total complication triple I method on complete BR0-algebra, and we apply the results to R0-Unite interval W. Not only we have simplified the proof of the results of R0-type triple I method on R0-Unite interval W, but also we make the proof to combine with the formal deductive system for fuzzy propositional calculus. This work also explains that the R0-type triple I method is a matching fuzzy inference with B?

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
