| Abstract: | This paper,by constructing a logical sketch map about relation of values,mainly depicts 4 equivalent expressions,4 contradictory expressions and 32 implications 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.They can be understood through examples by natural language,and be applied in thinking activities. |
