从换路定律证明看扩充实数的必要性

指出了在电路分析课程中换路定律证明方面存在的矛盾,证明矛盾的根源在于实数的完备性,并依此说明了建立广义实数概念的必要性.     

有界模糊数的比较与排序

利用两模糊数之间的距离公式,将模糊数之间的比较转换为模糊数与纵轴距离之间的比较。在此基础之上定义了模糊数空间上的序关系,并证明了它们的一些性质。这种方法的排序效果与人们的直觉是一致的且不悖逆于实数的自然序。利用距离方法定义的序关系,便于理解与计算机实现。     

Hilbert‘s Sixteenth Problem and Its Generalization

This paper deals with Hilbert‘s 16th problem and its generalizations.The configurations of all closed branches of an algebraic curve of degreee n are discussed.The maximum number of sheets for an algebraic equation of degree n and the maximum number of limit cycles for a planar algebraic autonomous system are achieved.The author also considers different generalizations and some related problems.     

三个连续的发现与用几何方法研究数论的新构想

在对毛比斯面的证明方法的深入研究中，发现了一种证明方法——“递推法”；在对“递推法”的进一步探索中，发现了一类新几何体——“棱环体”；在研究“棱环体”的边数的变化规律中，得到了一张“数表”，对“数表”的进一步研究，又相继发现了“最大公约数定理”、“素数规律”等．“棱环体”的发现，引发了“扭曲几何学”的构想；“数表”的发现，为一种新的数论研究方法——“数论的几何研究法”的提出，奠定了基础。     

Discriminating Quantity: New Points for Teaching Children with Down Syndrome About Number?

ABSTRACT

The focus of much mathematics teaching has been on the acquisition of counting, an area where children with Down syndrome can experience particular difficulties. Research with typically developing children has highlighted how early awareness of quantity provides a strong platform for the acquisition of later mathematical skills and programmes of early intervention have been introduced. Many of these studies are embedded in the work and traditions of developmental and cognitive psychology and can be difficult to access. Consequently, this is an area that has been largely ignored in the curricula of children with Down syndrome. This paper seeks to make this literature more available. It systematically reviews previous research with children with Down Syndrome on these early foundations. It considers seemingly contradictory findings in the light of differences in tasks, their presentation and instructions, and the responses required, in order to draw conclusions and reflect on the implications for teaching and learning. Some of these propositions are in contrast to existing practices and call for further research to test their effectiveness.
