利用有限Abel群构造一类结合方案

Constitute a Type of Association Scheme by Using Finite Abelian Group

根据任一非循环Ｐ群的有限Ａｂｅｌ群Ｇ均可分解它的子群的直和这一事实，利用Ｇ的直和分解式构造出了一类具有ｎ个结合类的结合方案．

According to the fact that any finite Abelian group G but cyclic p-group can be breaked down into the direct sum of subgroups of G, a new type of association scheme with n association classes has been constituted by using the decomposition of G.
