模态逻辑

The similarity logic calculus systems based on incomplete information and incomplete case knowledge is constructed by using a first order modal logic and a simplified second order predicate calculus. The grammar、semantics and inference rule are described.

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

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".
