%X The authors briefly analyze the present situation of Pawlak Rough sets, and emphatically introduce the definitions of S-rough sets and Function S-rough sets, two mathematical structures and the dual forms, The authors detailedly summarize the relation between S-rough sets and Pawlak Rough sets, the relation between function S-rough sets and S-rough sets Pawlak Rough sets, and the relation between function S-rough sets and Pawlak Rough sets. At last the authors give the available applications of S-rough sets theory,
