相图识别与相图的计算机管理系统

Pattern Recognition of Phase Diagram and Its Computer Management System

本文在建立相图数据库的基础上,提出了一种基于模式识别与模糊概念的相图录入方法。通过图象扫描仪将相图扫入,形成映像(image)文件,再由计算机来自动识别相图,将图中相线上的点以数据形式进行存贮,实现读取数据自动化。本文还介绍了该相图数据库管理系统的功能,并对其进一步的应用给出了实例。

In this paper, a new method based on the pattern recognition and fuzzy concept is proposed for the computer input of the phase diagrams. The management aspects of data base development are discussed which can intelligently manipulate the input/output, retrival, modification and some elimination of the phase diagrams. For the application of such a diagram database, an effort of extracting the thermodynamic data from the phase diagrams has been made, the method of fitting thermodynamic properties from the phase equilibrium data is introduced which is based on the Regression-Marquard Two-Step Fitting technique, and an example is given in the present paper.
