| 摘 要： | 模糊粗糙集(FR)是基于知识的不确定性提出来的，由于其处理信息系统中知识的不完善、不确定问题较粗糙集和模糊集有其自身的优点，近年来模糊粗糙集理论越来越受到国际学术界的关注，文章所讨论了模糊粗糙变换的性质并用模糊粗糙变换的保并性质证明了模糊粗糙集的扩张定理。

| Abstract: | Fuzzy rough sets are raised based on the uncertainty of knowledge. Because they have many advantages in dealing with the imperfect and uncertain problems, they have been paid much attention by international academic circles compared to fuzzy sets and rough sets,. The properties of the fuzzy rough conversion are discussed and the extension theorem of fuzzy rough sets is proved based on the protection combination property of the fuzzy rough conversion. |
