平衡不完全区组 meaning in Chinese

balanced incomplete block

The confounding design and the balanced incomplete block design were introduced from the fundamentals of special design , which may be applied to the experiment with fewer homogeneous experimental units and more treatments
根据特种设计的基本原理，介绍了用混杂设计、平衡不完全区组设计以实施基因型同质试验单元较少而处理数较多的试验。
A directed balanced incomplete block design ( dbibd ) with order v , block size k and index a , denoted by db ( k , ? ; v ) , is a pair ( x , a ) , where x is a set of v points and a is a collection of transitively ordered k - tuples ( called blocks ) of x , such that each ordered pair of distinct points of x occurs exactly in a blocks
一个阶为v ，指标为及区组大小为k的有向平衡不完全区组设计， db ( k ，； v ) ，是指一个序偶( x ， a ) ，其中x是一个v元点集， a是x的一族可迁有序k元子集(叫做区组) ，使得x中任意两个相异点组成的有序对恰出现在个区组中。
