【摘要】 几何构造分析是结构力学课程的重要基础知识,其特点是利用几何构造分析的基本规律,分析出几何结构的形态。几何构造分析专家系统GSAES就是用于帮助学生学习和掌握有关的几何构造分析基本规律和分析技巧的CAI软件。该软件有四项主要功能:(1)示教功能:演示几何构造分析的基本概念、规律及该软件的使用方法;(2)获取信息:建立或选择所要分析结构的有关信息;(3)几何构造分析:对该结构进行几何构造分析;(4)推理路径解释:用彩色的图形配以文字说明交互式解释推理路径。本文探讨了实现几何构造分析专家系统GSAES的几个主要问题,包括知识的表示与获取、推理机及其解释功能的实现等。作为计算机辅助教学软件,我们特别强调推理机的解释功能要强,为此我们实现了图文并茂的人机交互界面。更多还原

【Abstract】 The geometrical structure analysis is a basic technology in structurial mechanics. In this paper, an expert system of geometrical structure analysis , used for CAI, is presented. Some main problems discussed are the expression of knowledge, getting knowledge, the reseasoning strategy and its explanation etc. The GSAES has four main functions: (1) Tutorial-some basic conceptions and rules used by GSAES, and some helps of how to use the GSAES; (2) Taking basic information of the plane structure;(3) Analysing a plane geometrical structure, and giving some results; (4) Showing the reasoning route. Differentiated from other expert systems, the GSAES can give an explanation of resoning route with colorful diagrams. GSAES is programmed by TURBO PROLOG.更多还原
