Firstly, an equivalence proposition of right qpm-injective module is discussed, and when the endomorphism of right qpm-injective module is right pm-injective ring is observed.

首先，讨论右qpm-内射模的一个等价命题，以及在什么情况下，右qpm-内射模的自同态环是右pm-内射环。

Disjunction normal form theorem in the modal logic system S5 is inductively proved, which can be used for representing complex modal formulas by means of conjunction and disjunction of simplest modal formulas with depth at most 1 in the system S5. As application, it is proved that a knowledge base could answer KB-queries if and only if it could answer queries of non-modal propositions and their negations, which is a basic problem on knowledge base.

研究了模态逻辑系统S5中的析取范式定理的归纳证明，给出了在S5中用深度至多等于1的最简模态公式通过析取与合取运算表示含有多重模态词的公式的方法，作为范式定理的应用，讨论了知识库中的一个基本问题，证明了知识库能够回答KB命题式问题的充要条件是该知识库能够回答相关的非模态命题及其否定命题的问题。

Part Three The study of Lattice-valued Modal First-order Logic System and Its Resolution Principle In this part, we introduced quantifiers and predicate into LMP, put up lattice-valued modal first-order logic system LMF, and gave its semantic interpretation and syntax structure, proved soundness theorem and consistence theorem. Moreover, in order to judge the satisfiability of formula, defined Skolem standard type and H-interpretation. Based on these work, made a primary discussion of a - resolution principle based on LMF.

第三部分：关于格值模态一阶逻辑系统及其归结原理的研究第n页西南交通大学博士研究生学位论文这一部分主要是在格值模态命题逻辑系统LMP队）中引进量词和谓词，建立格值模态一阶逻辑系统LMF（广并给出其语又解释和语法结构，证明了系统的可靠性和协调性；另外，为了判断公式的可满足性，定义了格值模态一阶公式的 Skolem标准型和体解释；在此基础上，对基于系统LMF的a一归结原理进行了初步探讨。

Analysis is conducted on model checking for three valued logic formulae of modal transition system using existing model checking techniques. We reduce the three valued logic model checking problem for modal transition system to the two valued model checking problem under Kripke structure. This reduction is linear in the number of states, size of transition relations, and number of atomic propositional formulae in the new formed model compared with those in the original model. It does not increase the comple...

分析了现有的模型检验技术应用于模态转移系统的三值逻辑公式的模型检验中存在的问题·提出了把模态转移系统转换成Kripke结构的算法以及三值逻辑公式转换成2个二值逻辑的算法，经过转换后可用现有的模型检验技术进行模型检验·用该算法转换后，状态数、转移数和原子命题数目与原模型呈线性关系，没有增加模型检验的复杂度

At the basic of knowledge implication propositional logic, a system of knowledge implicational model prepositional logic system has been built. It can describe inference mechanism of inconsistent knowledge system which includes in modal information.

在知识蕴涵命题逻辑的基础上，构建了一个知识蕴涵模态命题逻辑系统，它可以描述包含模态信息的不协调知识系统的推理机制。

Traditional logic and modern logic have some defects in analyzing the hypothetical proposition of natural language.

传统逻辑和模态逻辑在分析自然语言假言命题方面都存在缺陷。

It holds that, by means of logic inference,"x believes p" can be interpreted as "x thinks that p is true". By the same token, the system of the Logic of Belief can-be established, on the basis of the logic of its classical proposition, by adding the modal auxiliary "should "before t...

作者认为，从逻辑的观点出发，可以简单地将&x 相信 p&解释为&x认为p是真的&，与之相对应，信念逻辑系统可以在经典命题逻辑的基础上加入模态词&应该&而得以建立。

It holds that, by means of logic inference,"x believes p" can be interpreted as "x thinks that p is true". By the same token, the system of the Logic of Belief can-be established, on the basis of the logic of its classical proposition , by adding the modal auxiliary "should "before the verb "believe".

作者认为，从逻辑的观点出发，可以简单地将&x 相信 p&解释为&x认为p是真的&，与之相对应，信念逻辑系统可以在经典命题逻辑的基础上加入模态词&应该&而得以建立。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
