数理统计是研究大量现象在数量上的规律性的一门科学。它在工业生产和科学实验中得到广泛的应用。近年来,由于钢铁工业的发展,在轧钢生产中开展开大量的研完工作。无论对设备能力的标定或对生产工艺的分析和改进,都要进行大量的数据处理,轧钢工人与工程技术人员对数理统计方法的了解和掌握就日趋迫切了。因此,从本期开始将陆续以轧钢生产中的一些代表性问题为例;介绍一些数理统计的基本知识和应用方法,供需用者参考。
Mathematical statistics is a science that studies the quantitative regularity of a large number of phenomena. It is widely used in industrial production and scientific experiments. In recent years, due to the development of the steel industry, a great deal of research work has been done in the production of rolled steel. No matter the calibration of equipment capacity or the analysis and improvement of the production process, a great amount of data processing is required. The knowledge and mastery of the mathematical statistics methods of the steel-rolling workers and engineers is becoming more and more urgent. Therefore, from the beginning of this issue, one after another will take some typical problems in the production of rolled steel as an example; introduce some basic knowledge and application methods of mathematical statistics for reference of users.
