摘　　要：从副集的代数系统方面进行研究,讨论了近似空间上单向S-粗集的副集的代数性质,给出副集的交、并、补的定义。基于此,多方面探讨了副集的代数性质,如:它是一个偏序、分配格、软代数。Focused on the algebraicproperty of assistant sets of single-direction S-rough has been discussed in approximate space and defined union, intersection and complerties of assistant sets. With such, the algebraic property of assistant sets has been further explored in various ways, such as the situations when they are a partial order, assignment lattices and soft algebraic.
