两水平析因试验是析因试验中较常用的一种研究试验方法 ,可以同时在多个因子的选优区内一次布置多个试验点 ,通过对试验结果的比较和分析 ,找出对试验结果有影响因子的主次 ,选取最优组合 ,提取有用的信息。本文深入浅出地讨论了在有或无交互效应和重复试验的情况下 ,用直观法和方差分析法等进行比较分析 ,用回归分析法建立研究试验对象简单的数学模型。
Two horizontal factorial experiment is a more commonly used in the factorial test research and test methods, multiple factors can be selected at the same time a number of test sites at a time, through the comparison and analysis of test results to identify the test The results of the influential factors of the primary and secondary, select the optimal combination, extract useful information. In this paper, we discuss profound theories in simple language and in the absence of interaction effects and repeated experiments, using the direct method and the analysis of variance to compare and analyze, using regression analysis to establish a simple mathematical model for the study of the test object.
