摘　　要：研究基于面向属性概念、面向对象概念的对象粒的属性逻辑公式描述问题,讨论共有属性概念格和面向属性概念格、面向对象概念格的关系,在基于概念格的共有属性分析的对象粒描述方法基础上,给出基于面向属性概念格的可能属性分析的对象粒描述和基于面向对象概念格的必然属性分析的对象粒描述,分析属性逻辑公式语义构成的面向属性概念的外涵、面向对象概念的外涵的属性逻辑公式的结构特征,有助于应用对象粒的属性逻辑公式描述构建面向属性和面向对象的概念格.The attribute logical formula descriptions of object granules based on the property-oriented concept and the object-oriented concepts are studied.The relationships between common attribute concept lattice and property-oriented concept lattice as well as common attribute concept lattice and object-oriented concept lattice are discussed.On the basis of the object granule description method of concept lattice of common attribute analysis,the object granule descriptions based on property-oriented concept lattice of possible attribute analysis and object-oriented concept lattice of necessary attribute analysis are given,respectively.Structural characterizations of attribute logic formulas are analyzed respectively,the semantic of these attribute logic formulas are exactly the extent of property-oriented concept or object-oriented concept.The attribute logical formula descriptions of object granules are helpful to construct the property-oriented and the object-oriented concept lattices.
