压水堆控制棒导向筒结构改进对落棒的影响

为改善横向水力载荷对控制棒导向筒的作用，对靠近上腔室出口管嘴附近的控制棒导向筒（对称的４组：０２－２６，０３－２５，１１－２９，１２－２８）加设了保护套．在秦山核电站压水堆上腔室１４的可视化模拟体中，以水为介质进行了实验研究，把结果与未加设保护套的实验结果作了分析比较，得到了对靠近上腔室出口管嘴附近的控制棒导向筒加设保护套有助于改善流场对控制棒导向筒的水力载荷作用和确保控制棒能按指令在导向筒中自由升降和快速下插的结论．     

实验性脾虚证大鼠血清中微量元素含量的研究

用破气苦降药加饮食失节法复制了大鼠脾虚证模型。采用原子吸收光谱法检测了血清发Ｚｎ、Ｃｕ和Ｆｅ的含量。本研究证明，脾虚证大鼠血清Ｚｎ值明显降低（Ｐ＜０．００１）；Ｃｕ值、Ｆｅ值无明显差异（Ｐ＞００５）；Ｃｕ／Ｚｎ比值上升。用中药加味四君子汤治疗后，血清Ｚｎ值明显回升并高于正常水平（Ｐ＜００５），Ｃｕ值回升（Ｐ＜０．０５），但Ｆｅ值和Ｃｕ／Ｚｎ比值与自然恢复及对照组比较无显著性差异。这说明：１．脾虚组Ｚｎ的降低可能与消化吸收障碍有关；２．加味四君子汤对脾虚证时血清Ｚｎ及Ｃｕ／Ｚｎ比值的变化有明显的调整和恢复作用．     

多自由度系统振动的Barnett-Lothe矩阵

利用Stroh理论的本征方程与多自由度振动的方程非常相似特点,将Stroh理论推广到多自由度系统振动的分析研究中,获得多自由度振动的Barnett-Lothe矩阵及Barnett-Lothe积分公式,避免了求解特征值和特征向量的麻烦。

中山大学校园传统建筑风格评析

本文研究对象为现存于广州中山大学（南校区）校园内建于1936年以前传统建筑。通过对这些建筑的分析，根据建筑风格的不同将中山大学传统建筑分为两个时期：折衷主义时期（1904-1928）和古典复兴主义时期（1928-1936），对这两个时期的建筑风格分别进行概括，并列举了一些代表性的建筑实例。     

On the Foundations of Constructive Mathematics – Especially in Relation to the Theory of Continuous Functions

We discuss the foundations of constructive mathematics, including recursive mathematics and intuitionism, in relation to classical mathematics. There are connections with the foundations of physics, due to the way in which the different branches of mathematics reflect reality. Many different axioms and their interrelationship are discussed. We show that there is a fundamental problem in BISH (Bishop’s school of constructive mathematics) with regard to its current definition of ‘continuous function’. This problem is closely related to the definition in BISH of ‘locally compact’. Possible approaches to this problem are discussed. Topology seems to be a key to understanding many issues. We offer several new simplifying axioms, which can form bridges between the various branches of constructive mathematics and classical mathematics (‘reuniting the antipodes’). We give a simplification of basic intuitionistic theory, especially with regard to so-called ‘bar induction’. We then plead for a limited number of axiomatic systems, which differentiate between the various branches of mathematics. Finally, in the appendix we offer BISH an elegant topological definition of ‘locally compact’, which unlike the current definition is equivalent to the usual classical and/or intuitionistic definition in classical and intuitionistic mathematics, respectively.

Distributed and Parallel Component Library

Software component library is the essential part of reuse-based software development. It is shown that making use of a single component library to store all kinds of components and from which components are searched is very inefficient. We construct multi-libraries to support software reuse and use PVM as development environments to imitate Iargescale computer, which is expected to fulfill distributed storage and parallel search of components efficiently and improve software reuse.
