冶金熱力學數據庫應用系統的系統構成

The Architecture of Metallurgical Thermodynamic Database Application System

摘要: 本文從冶金熱力學數據庫應用系統如何在M-150計算機上實現的角度,介紹它的機器環境和系統構成。它由四部分構成:
1.數據庫:存貯有399種二元系合金和2211種化合物(或元素)的熱力學數據。
2.數據管理系統:主要完成對數據庫中所有數據檢索、修改、插入、刪除等任務。
3.應用程序庫:由七個復雜的計算程序組成,完成化學平衡體系的熱力學性質的計算。
4.監控系統:協調整個系統,使之正常工作。

Abstract: The environment and architecture of Metallurgical Thermodynamic Database Application System (METHEDAS) which is implemented on the computer HITACH M-150 are described in this paper.
This special database system consists of the following blocks:
1. a database, having memorized all the thermodynamic data of 2211 kinsd of inorganic substances (including elements) and 399 binary alloy systems;
2. a data management system, being able to provide users with four basic functions, namely Select, Update, Delete, Insert;
3. an application program library, having seven programs available forusers to calculate the thermodynamic qroperties of the chemical equilibrium systems;
4. a monitor system, monitoring and coordinating the activities of METHEDAS,
