根据对常见实验设计的系统回顾 ,本文指出名目繁多和缺乏系统性是现有实验设计在名称上存在的问题 ,据此本文进一步提出了实验设计体系的概念。接着通过对实验设计本质属性的深入讨论 ,本文认为 ,基本的实验设计可分为两类 ,两类基本的实验设计构成了实验设计体系的基础。 According to the systematic review of common experimental designs, this paper points out that the variety of names and the lack of systematicness are problems existing in the design of existing experiments. Based on this, we further put forward the concept of experimental design system. Then through the in-depth discussion of the nature of the experimental design, this paper argues that the basic experimental design can be divided into two categories, two types of basic experimental design constitute the basis of the experimental design system.
