As an application of the above proof, we obtain at once that there is an open and dense set in the set of Ω-stable systems such that every system in the set satisfies Axiom A and the no-cycle condition (Axiom A and the strong transversality condition, respectively).

作为上述方法的一个运用，马上可以得出在Ω稳定系统的集合中有一开稠集满足公理 A 和无环性条件(对应的，公理 A 和强横截性条件)。

Set cover greedy algorithm is one of the commonly used algorithms for the test set problem. It is an open problem if the approximation ratio 2ln n+1 directly derived from the set cover problem can be improved.

集合覆盖贪心算法是测试集问题的一个常用近似算法，其由集合覆盖问题得到的近似比21nn+1能否改进是一个公开的问题。

The difference update operation returns a set whose elements are members of the original set after removing elements that are members of the other set.

差更新操作返回一个集合，该集合中的成员是去除掉另一集合中元素后的结果集。

According to mapping relationship between information set and discrete point set, every user was entitled to access an information sub-set. Therefore, a correspondent template was activated, and it was used to encapsulate manufacturing information for the users.

根据信息集与离散点集之间的映射关系，从用户的权限区域映射出用户有权限的信息子集，被该子集激活的制造信息模板的实例将最终用于制造信息的共享。

In this thesis, we defined duality Fuzzy relation in a pointwise Fuzzy set by a set of duality Fuzzy point. Then we defined Fuzzy congruence and Fuzzy rough set in Fuzzy semigroups.

本文把二维模糊点作成的集合定义为一个点态化模糊集上的模糊二元关系，进一步定义模糊同余关系，并通过它又定义点态化模糊集上模糊粗糙子集，并研究了它们的一些性质。

Introducing a neighborhood relation to set valued information systems,we established a rough set approach based on the neighborhood of every object as elementary set.

在集值信息系统上引入对象的邻域关系，并以每个对象的邻域作为基本集，建立了集值信息系统的粗糙集方法。

As a result, the concept of an optimal set of elementary siphons is proposed and also the algorithm which can be finished in polynomial time to find such a set. With the set of optimal elementary siphons, net supervisors can generally produce maximalreachable states.

但是上述理论虽然只需要控制基本信标即可以控制整个系统，但是由于从属信标满足一定的可控性条件才能完全受控，这意味着在控制算法的生成过程中所有的信标都要参与，从而大大增加了系统控制的复杂性。
