实验中经常遇到涉及两个因素的实验,若两因素有交互作用,则需采用析因设计、正交设计等设计类型,但这些设计通常需要进行较多次实验.若在理论和专业上可以证明实验中涉及到的两个因素不存在交互作用,或交互作用对观测结果的影响无统计学意义,并且特定实验条件(通常为各因素不同水平的一种组合)下实验数据的测定误差在专业上允许的范围之内,则可采用无重复实验的随机区组设计、无重复实验的平衡不完全随机区组设计、具有一个重复测量的单因素设计、无重复实验双因素设计和两因素嵌套设计.本文结合实例,重点阐明前3种实验设计类型.

Two-factor designs are quite commonly used in scientific research.If the two factors have interactions,research designs like the factorial design and the orthogonal design can be adopted; however,these designs usually require many experiments.If the two factors have no interaction or the interaction is not statistically significant on result in theory and in specialty,and the measuring error of the experimental data under a certain condition (usually it is one of the experimental conditions which is formed by the complete combination of the levels of two factors) is allowed in specialty,researchers can use random block design without repeated experiments,balanced non-complete random block design without repeated experiments,single factor design with a repeatedly measured factor,two-factor design without repeated experiments and two-factor nested design.This article introduced the first three design types with examples.
