模态复合命题与复合模态命题间真值关系考察

On Relation of Compound Proposition of Modality and Modal Proposition of Compound Form

本文通过构造一个逻辑关系示意图 ,重点刻画了模态联言命题、模态选言命题与联言模态命题、选言模态命题之间所存的四个等值式、四个矛盾式和三十二个蕴涵式 ,这些等值式、矛盾式和蕴涵式都与人们的实际思维密切联系 ,均可借助自然语言的实例得到直观理解 。

This paper by constructing a logical sketch map about relation of values mainly depicts 4 equivalent expressions, 4 contradictory expressions and 32 implication expressions between conjunctive proposition of modality or disjunctive proposition of modality and modal proposition of conjunctive form or modal proposition of disjunctive form. These expressions are closely related to our practical thinking activities, and can be understood through examples by natural language, and be applied in thinking activities.
