平衡不完全区组设计 在“不完全区组”设计里,处理数多于单个区组所能包容的。“平衡不完全区组”设计是不完全区组设计的一种,在这种设计里,任何给定的一对处理,例如A与D,或C与B,在整个实验中出现于同区组的次数相等。 在实践中,有时由于客观原因,如实验设备或仪器的短缺,区组的容量受到限制,在单个区组里不能容纳所要试验的全部处理,所以这种区组设计是“不完全的”;但各种处理在整个实验中出现的次数相同,故又是“平衡的”。
Incomplete Block Design In the “Incomplete Block” design, there are more processes than can be tolerated by a single block. The “incomplete balanced block” design is a type of incomplete block design in which any given pair of processes, such as A and D, or C and B, appear throughout the experiment in the same area The same number of groups. In practice, such block design is sometimes “incomplete” due to objective reasons such as shortages of experimental equipment or equipment, limited capacity of the block, and failure to accommodate all of the processing to be tested in a single block; However, the various treatments appear the same throughout the experiment, so they are “balanced.”
