概念的限制

On Restriction of Conception

在概念结构系统中,概念限制是导致概念向下运动的逻辑方法,包括属性限制与数量限制。概念每增添一项属性限制导致概念层次下降一级:限制所得到的概念类属于被限制概念。概念的量词限制也导致概念降级,即降低到该量词所限定的层级单位;数词与量词结合对概念进行限制,不再导致概念降级,而是构成该概念一定层级单位的集合。量词命题由一个数量前提和一个受此数量制约的逐指性单称命题两部分组成,确切地说是一个逐指性单称命题的集合。用数学公式表达则是:数量×逐指性单称命题。各种量词命题除了数量的不同以外,没有其他区别。

In the system of conceptual structure,the restriction of conception is a logical method leading the conception downward movement,including restriction of attribute and restriction of quantity.When the conception adds one restriction of attribute,it will lead the conception level going down one level.The conception class obtained by the restriction belongs to the restricted conception.The quantifier restriction of the conception also leads to the deduction of class,meaning,falling into the level unit that restricted by the quantifier.If the numeral and quantifier combined to restrict the conception,the conception will no longer lead to deduction,it will constitute a certain level set of the conception.The proposition of quantifier is consisted by a quantity premise and a singular proposition which subjected to this quantity and more correctly,a collection of a singular proposition.If it is expressed by the mathematical formula,it will like this：quantity x singular proposition.There is no other difference in all kinds of quantity proposition except the numeral.
