Abstract: By using function S-rough sets (function singular rough sets), rough law generation and the theorem of rough law generation were given. Based on the above results, rough law separation, the separation theorem of rough law, the compound generation theorem of rough law band, and the principle of rough law band were proposed. Finally, an application of rough law separation in recognizing the risk law of profit was presented.

Key words: the principle of rough law band , the theorems of law separation, law separation, rough law, dual of function one direction S-rough sets, function one direction S-rough sets
