并行广义预测自校正控制器(GPC)

本文旨在讨论ＧＰＣ算法［１，２］的并行化问题，通过对原串行算法的数据流及数据相关性的分析，得到了一种三角阵列的并行算法。该算法自然导致Ｓｙｓｔｏｌｉｃ结构，并具有良好的数值稳定性。对于一个 ｎ阶系统而言，本算法采用Ｏ（ｎ２）阶的处理器单元互连成三角阵列，可以把计算时间由原来的Ｏ（ｎ３）阶（内积运算）时间提高到 Ｏ（ｎ）阶，因而具有 Ｏ（ｎ２）的加速比，其处理器的利用效率得到了很大提高。     

CH_3COONa·3H_2O-Na_2SO_4·10H_2O截面

用步冷曲线法和DSC法测定了CH_3COONa·3H_2O-Na_2SO_4·10H_2O截面,得到了体系的多温图。结果表明,此截面的两条三次结晶水平线的温度值分别为: 液+Na_2SO_4(?)Na_2SO_4·10H_2O+CH_3COONa·3H_2O_2:18.2℃; 液+CH_3COONa(?)Na_2SO_4+CH_3COONa·3H_2O:58.1℃。

Mathematical model of the identical slope surface

The formation of the identical slope surface and the method of construction are discussed. On the basement of building the parameter equation of variable-radius circle family envelope, the frequently used parameter equation of the identical slope surface of the top of taper moving along column helix, horizental arc and line is built. The equation can be used to construct the identical slope surface’s contours, gradient lines and three dimensional figures correctly.

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.     

基于语言偏好的群体决策的软解法

群体决策模型用于支持系统或专家系统，面临的两个问题是：自然语言与机器语言的匹配以及模型解与决策者意向交融．本文在许多学者大量工作的基础上，试图提出群决策的软化求解模型．主要提出两方面的结果：一是多准则语言偏好的综合；二是采用模糊匹配方法和语言变量的软算法将个人语言偏好聚集为群体可接受决策解．最后给出实例计算以说明操作步骤．该模型可用于人－机交流式ＧＤＳＳ或小群（７～１２人）会议支持系统的软件设计
