1) subsemiring
子半环
1.
By widening the satisfactory conditions of the subsemiring of semiring,the concept of nearly-ideal of semiring is introduced,several elementary properties of nearly-ideal are discussed,and some new conclusions are obtained.
通过对半环的子半环所满足的条件进行加强,提出了半环的近理想的概念。
2) rough subsemirings
粗糙子半环
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。
2.
The paper suggests the properties of rough subsemirings and rough ideal.
研究了半环的粗糙子半环和粗糙理想的性质;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。
3) fuzzy semi-subring
模糊子半环
1.
Using the concept of fuzzy spaces,we redefine semi-ring and fuzzy semi-subring and give theorems of them.
在模糊空间定义的基础上重新定义了模糊半环,模糊子半环并对其基本性质进行了研 究,这是传统模糊半环理论的推广和延伸。
4) subdirect product of semirings
半环的子直积
5) the star semirings of no star factor
无星因子-幺半环
6) Rough-fuzzy subsemirings
粗模糊子半环
