摘要
首先定义了具有足够幂等元的群分次环的Ｓｍ ａｓｈ 积并讨论其性质，其次，借助Ｓｍ ａｓｈ 积给出了这类分环上的分次Ｍｏｒｉｔａ对偶的刻划．
In this paper, smash products over group graded rings with enough idempotents are defined, some of its properties are proved and the characterization of Morita dualities over group graded rings with enough idempotents are given by means of the smash products.
