The primary contributions of this thesis include : having studied the rough set theory carefully , the thesis finds the relationship between rough set and such abstract theories as modal logic , fuzzy set , algebra system and interval - set algebra , i . e . , rough set provides a well defined semantical interpretation to these abstract theories , which enables us to better understand them . secondly , rough set builds an inter - relationship among these dependent theories and connects them together
完成的工作和取得的创新性成果在于：经过对粗糙集理论的深入研究，作者找到了粗糙集与模态逻辑、模糊集、代数系统和区间集代数等抽象理论之间的关系，一是粗糙集可以为抽象理论提供语义解释，从而使我们能更好地理解掌握这些抽象理论；二是粗糙集建立了各个独立的抽象理论之间的内在关系，使彼此独立的抽象理论联系在了一起。
