Elastically-induced shift of system-spanning cluster formation in water/oil-microemulsion networks

The influence of ABA-triblock copolymers on the temperature-induced infinite droplet cluster formation in water/oil-microemulsions is studied. The effects of the different blocks of the polymer can be well separated. With the help of an Ehrenfest relation the coupling between the elastically-induced shift of the infinite cluster formation temperature T_c and the plateau modulus of the resulting microemulsion networks is described.     

定义在区间值上的Fuzzy关系方程

Ｆｕｚｚｙ关系方程Ａ。Ｘ＝Ｂ中的矩阵Ａ、Ｂ的元素均为区间值，称为定义在区间值上的Ｆｕｚｚｙ关系方程。它是目前关于Ｆｕｚｚｙ关系方程理论研究中的主要问题之一￣［１］。本文讨论了区间值上Ｆｕｚｚｙ关系方程解的定义，并用符号定值法求出其全体解集。     

On the semilattice of weak orders of a set

Order theoretic and combinatorial properties of the semilattice of weak orders on a set are developed. In the case of a finite set, an order theoretic characterization of this semilattice is obtained.

中美行政公开制度比较研究

行政公开是我国建设社会主义政治文明的一项重要内容。美国行政公开制度堪称世界各国的典范，它所确立的行政公开的基本原则、公开的方法、程序及救济的途径，都值得我国借鉴。     

基于模糊理论的人才双向选择问题应用软件

基于模糊集理论开发了一种人才双向选择应用软件，由该理论在［０，１］区间取值及隶属函数等概念，把模糊命题量化，在构造关系矩阵基础上，对其中每一元素用真值、导出置信度、综合真理值进行检验排出无效元素，经排序得出所需结果，实用结果表明，用Ｐｒｏｌｏｇ语言开发的应用软件运作的结果与人为的主观判断一致。     

软代数的素M－理想与同余关系

在文［１］中，裴礼文教授引入了软代数的Ｍ－理想的概念。本文在此基础上，定义了对偶Ｍ－理想、素Ｍ－理想、素对偶Ｍ－理想等概念。并讨论了它们的若干性质及相互关系。证明了由一素Ｍ－理想，可确定软代数Ｌ的一个同余关系，这时Ｌ可同态于一个四元软代数或一三元软代数。

Condorcet Winners for Public Goods

In this work, we consider a public facility allocation problem decided through a voting process under the majority rule. A location of the public facility is a majority rule winner if there is no other location in the network where more than half of the voters would have been closer to than the majority rule winner. We develop fast algorithms for interesting cases with nice combinatorial structures. We show that the computing problem and the decision problem in the general case, where the number of public facilities is more than one and is considered part of the input size, are all NP-hard. Finally, we discuss majority rule decision making for related models.
