摘　　要：基于近似空间,对原始S-粗集模型进行了扩展.提出了基于模糊近似空间的S-粗集模型,讨论了模型的上下近似算子的性质;接着分析了此模型与已有模型的相互关系,最后通过实例对此模型进行了说明.Based on the approximate space, the primitive S-rough set model was expanded. S-rough set model on fuzzy approximation space was proposed, the basic properties of approximation operators were investigated; then the relationship between this model and the existing model were analyzed; finally, this model is illuminated through example.
