Soluble block - transitive automorphism groups of an incomplete block design 一類不完全區(qū)組設(shè)計(jì)的可解區(qū)傳遞自同構(gòu)群
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 根據(jù)特種設(shè)計(jì)的基本原理,介紹了用混雜設(shè)計(jì)、平衡不完全區(qū)組設(shè)計(jì)以實(shí)施基因型同質(zhì)試驗(yàn)單元較少而處理數(shù)較多的試驗(yàn)。
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 一個(gè)階為v ,指標(biāo)為及區(qū)組大小為k的有向平衡不完全區(qū)組設(shè)計(jì), db ( k , ; v ) ,是指一個(gè)序偶( x , a ) ,其中x是一個(gè)v元點(diǎn)集, a是x的一族可遷有序k元子集(叫做區(qū)組) ,使得x中任意兩個(gè)相異點(diǎn)組成的有序?qū)η〕霈F(xiàn)在個(gè)區(qū)組中。
