Abstract: The concept of lower and upper approximation of soft sets with the same effect in Pawlak’s approximation spaces is introduced,some perfect properties of them about soft union,soft intersection and soft compliment are deeply studied,and a series of good results are obtained.

Key words: soft set, soft lower(upper) approximation, rough set

摘要: 在Pawlak近似空间上首次引入了等效软集的软上下近似的概念,研究了软上下近似的交、并、补代数运算的若干性质。结果令人满意。

关键词: 软集, 软上(下)近似, 粗糙集
