利用Z／P^αZ上矩阵构作多个结合类的结合方案与PBIB设计

USING MATRICES OVER z/p￣αZ TO CONSTRVCT ANASSOCIATION SCHEME AND PBIB DESIGNS WITHSEVERAL ASSOCIATION CLASSES

本文利用有限局部环Ｚ／ｐαＺ上的１×ｎ矩阵集合构作具α个结合类的方案与ＰＢＩＢ设计，并计算了它们的参数．

In this papers we use set of all 1×n matrices over a finite local ring Z/PαZ toconstruct an association scheme and PBIB designs with α association classes and computetheir parameters.
