摘　　要：引进并刻划了分次 Bass环 ,讨论了分次环 R及由它导出的非分次环 R,Re,R# G之间的 Bass环性质的关系 ,得到在有限群 G-型强分次环 ( |G|是 R的逆元 ,e是 G的单位元 )的条件下 ,R,Re,R# G与分次环 R在WT5BZ]Introduces and characterizes graded Bass rings,discusses the relations among graded rings R and the rings which are derived by it,R,R e,R#G and obtains R,R e,R#G and graded ring R are identical on the properties about Bass rings on the conditions of finite group G type strongly graded rings｜G｜ is inverse of R,e is the identity of G ).
