This article continues to study the application of rough set theory rough and algebra system -group, rings to combine research. So that rough algebra system is built better perfectly.

本文继续将粗糙集理论与代数系统——群、环理论结合起来进行研究，以此建立比较完善的粗糙代(来源：0cbdAcbBC论文网www.abclunwen.com)数系统。

On the generalization of rough set theory, molecular lattice was introduced into rough set theory as the base algebra.

关于粗糙集理论的拓展问题，将分子格引入到粗糙集理论，本文试图将近似算子作进一步抽象与推广。

The flow field structure over wedges of 30 o, 40 o and 50o by shadowgraph technique, and the sandpaper has been used to change the surface roughness of the model wedges. The shock reflection over wedges of 30o and 40o are of Mach reflection.

本实验使用影图法来撷取於斜角为30、40及50度之楔行体斜面上震波反射的流场结构，并利用砂纸来改变模型表面之粗糙度，从极度光滑至表面砂纸平均粗糙度为0.0174cm共做四组实验来进行分析与比较。

The notion of weak fuzzy similarity relations,a generalization of fuzzy similarity relations,is used to represent indiscernibility of elements.

为此提出用模糊相似关系和弱模糊相似关系的概念来代替等价关系，同时引入了弱模糊相似关系的相似度概念和相似类概念，定义了基于弱模糊相似关系的广义粗糙集及标准的广义粗糙集上下近似；研究了两对上下近似算子的性质，讨论了3种粗糙隶属函数的性质并验证了它们的性质。

At present , concentrate on the research of rough sets theory mainly: The popularization of the rough sets model collected, the uncertainty research of the problem, with other treatment uncertainty, fuzzy mathematics relation and complementation of theories of questions, the research of the pure mathematics theory, rough sets research and research of the artificial intelligence other directions relation that collect ,etc, some of the research is by the push that is used is produced , some of pure theories.

目前，对粗糙集理论的研究主要集中在：粗糙集的模型的推广，问题的不确定性的研究，与其他处理不确定性，模糊性问题的数学理论的关系与互补，纯粹的数学理论方面的研究，粗糙集的算法研究和人工智能其他方向关系的研究等，这些研究有的是受应用的推动而产生的，有的是纯理论的。
