摘　　要：函数S-粗集(function singular rough sets)是用R-函数等价类定义的,函数是一个规律,函数S-粗集具有规律特征.函数S-粗集推广了Z.Pawlak粗集.利用函数S-粗集,给出规律生成,规律分离的讨论,提出规律分离定理.给出的结果在投资分险规律估计中得到了应用.Function S-rough sets （function singular rough sets） is defined by R-function equivalence class. A function is a law, function S-rough sets has law characteristic. Function S-rough sets generalized the rough sets proposed by Z. Pawlak. By using function S-rough set, this paper gives discussion of law generation and law separation, and put forward the theorem of law separation. The results of this paper can be used in estimating risk law in investment.
