集合

Based on the flaw of the probability reliability model in the case of small amount of information,non-probability and mixed probability/non-probability reliability models are presented. When the uncertainty of the basic random variable is described by convex, analytical and numerical methods are constructed to calculate the convex of response variable. The infinite norm index, which is the minimal infinite norm distance from original coordinate point to the surface of the limit state in the standard interval space, is presented to measure the safety of the structure.

针对概率可靠性模型在小子样信息下的缺陷，建立了非概率可靠性模型及概率—非概率混合可靠性模型；给出了用集合来描述变量不确定性时，极限状态变量变化集合的解析解和数值迭代解法；提出了物理概念明确且十分易于工程应用的度量结构、机构安全程度的无穷范数指标，它是标准区间空间中坐标原点到极限状态表面的最小无穷范数距离。

The results show that if a convex game with a countable set of players is continuous at the grand coalition,then its core is the unique Von Neumann-Morgenstern stable set.

将稳定集的定义扩展到局中人集合是可数集的联盟对策中，并证明若局中人集合是可数集的凸联盟对策在总的联盟是连续的，那么它的核心是唯一的Von Neumann-Morgenstern稳定集。

First, two preprocess algorithms are designed to decompose a communication request set into some continuous cyclic sequences. Then the permutation group is used to represent the ring network with fixed converters and an algorithm is proposed to classify the wavelength channels into some groups.Based on these on these ideas,a wavelength assignment algorithm is presented.For an optical ring with any fixed conversion mode,the algorithm can giv a good assignment scheme.

首先，提出了两个对环网上的请求集合预处理的算法，这两个算法可以将请求集合分解成一些连续的循环序列；然后，采用置换群来描述具有固定波长转换器的光环网，基于这种数学表示，提出了对环网上的波长信道进行分解的算法；基于这些算法，进一步提出了一个波长分配算法，该算法对于环形光网上的任意固定转换模式都能给出一个较好的波长分配方案。

Methods Firstly,by definition it is proved that the minimality of a set is equivalent to the condition that the orbit of every point is dense in that set.

方法首先，利用定义证明一集合是极小的当且仅当每一点的轨道在该集合中稠密。
