近年来,我局在一些工艺改革和科学试验的项目中,应用华罗庚同志提出的单因素优选法取得了较好的效果。但是我们遇到的许多实际问题,往往都是比较复杂的,包含有多种因素,并且各个因素之间互有影响,这就需要我们对多种因素进行综合试验分析,才能得到良好的收效。正交试验设计就是一种针对多因素问题的试验方法,这种方法使用正交表来安排试验和分析试验结果,下面我们通过两个实际的例子来说明使用办法,并且把问题中的试验结果数
In recent years, the Bureau has used the single-factor optimization method proposed by Comrade Hua Luogeng in some technological reforms and scientific experiments to obtain good results. However, many of the practical problems that we encounter are often complex and involve a variety of factors. Each of these factors has an influence on each other. This requires us to carry out comprehensive experimental analysis of various factors in order to obtain good results. Orthogonal experimental design is a test method for multi-factor problems. This method uses orthogonal tables to arrange tests and analyze test results. Here we use two practical examples to illustrate the use of methods, and to test the results of the problem. number
