| Abstract: | 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. |

| Keywords: | S-rough sets law generation law separation the theorem and the application of law separation |
