几年来笔者在搜集、整理国内有关正交设计在混凝土试验中的应用实例和学习国内外有关经验中,认为有下列几个问题尚需商榷:(1) 如何选用合适的正交表和正确地分析混合水平表;(2)多指标怎样简化分析;(3) 在直观分析的基础上要不要进一步作方差分析以及怎样分析;(4) 误差如何处理等等。这些问题不仅直接关系到正交设计是否用得好,而且也涉及到是否用得成功的关键问题。本文将结合一些代表性实例探讨上述问题。
Over the past few years, the author has collected and sorted out the domestic application examples of orthogonal design in concrete tests and learned relevant experiences at home and abroad. He believes that the following questions are still needed to be discussed: (1) How to choose the right orthogonal table and correctly Analyze the mixed level table; (2) How multiple indicators can simplify the analysis; (3) Whether to do further analysis of variance and how to analyze it based on intuitive analysis; (4) How to handle errors and so on. These issues are not only directly related to whether orthogonal design is used well, but also related to the key issue of whether it is used successfully. This article will discuss some of these issues with representative examples.
