钢铁企业每天都要对出厂的钢材进行力学性能检验以判定产品是否合格。随着数理统计学的发展及工业管理现代化的要求,对大量检验数据进行科学管理,供随时检索及对数据进行统计分析,从中找出规律用以指导生产显得越来越重要了。为此我们在美国宝来公司B20微型计算机上建立了钢材力学性能数据库系统,试图探索大批量检验数据的管理和数据分析方法。本文从使用角度对该系统的功能作简要介绍。该系统用PASCAL语言写成,采用分层模块式结构,便于修改和扩充;人机介面全部用菜单选择和表格填写方式;并具有一 Steel companies every day to the factory for the mechanical properties of steel to test to determine the product eligibility. With the development of mathematical statistics and the requirements of the modernization of industrial management, it is more and more important to conduct scientific management of a large amount of test data, to retrieve and analyze the data at any time, and to find out the law to guide the production. To this end, we established a database of mechanical properties of steel materials on the Bora microcomputer of the United States Bora Company in an attempt to explore the management and data analysis methods of large quantities of inspection data. This article from the perspective of the use of the system functions briefly. The system is written in PASCAL language, using a hierarchical modular structure, easy to modify and expand; man-machine interface all with menu selection and form filling; and has a
