正交试验是利用正交表为工具来安排试验处理和计算分析试验的结果。所谓正交表是一种特制的表格,在田间试验方法之类的工具书附录可以查到。正交试验常用于复因子试验,从复因子试验的许多处理中,挑选几个处理进行试验。因此它可以解决因子和 Orthogonal test is the use of orthogonal tables as a tool to arrange the experimental treatment and calculation analysis of the results of the experiment. The so-called orthogonal table is a special form that can be found in an appendix to a tool such as the field test method. Orthogonal tests are often used in complex factorial experiments, and from the many treatments of complex factorial experiments, several treatments are selected for testing. So it can solve the factor sum
