1) rough quasi-ideal
粗糙拟理想
2) rough ideal
粗糙理想
1.
In this paper,the notion of a rough subsemiring is introduced;using the upper and lower approximations about a congruence on a subsets,the notion of the rough subsemirings on the semirings is given;and it is proved that the subsemirings and ideal of the semiribgs are the rough subseming and rough ideal of the semirings.
在半环上引入粗糙集并研究了粗糙子半环;利用半环的非空子集上关于同余关系的上、下近似,给出了半环的粗糙子半环的定义,证明了半环的子半环、理想一定是半环的粗糙子半环、粗糙理想。
