摘要
"不…而…"("舍…取…")是汉语常用的一个二元联结词,在形式语言中可以不用联结词,直接使用括号来表达"不…而…"("舍…取…")的语法功能。在括号表示法的形式语言中,"( )"有既有结构性功能,也有联结词功能,还有量词功能。基于纯粹的括号表示法,建立了以"舍…取…"作为初始联结词的命题逻辑自然推理系统Z_1和一阶自然推理系统QZ_1,它们与通常的命题逻辑系统和一阶系统等价,具有可靠性和完全性。
The expression "not…but…" is a binary connective commonly used in Chinese. In formal language,there is no need to use connectives but directly express the grammatical function of "not … but …" using parentheses. In the formal language of parenthesis notation,"()" functions as a structure,connective and quantifier. Based on the pure parenthesis notation,the natural inference system Z1 of propositional logic and the first-order natural inference system QZ1 which take "not…but…" as the initial connective are equivalent with the reliability and completeness of the usual propositional logic system and the first-order system.
