| Abstract: | This paper makes studies on injective precovers and injective covers of objects in Grothendieck categories.It also points out the sufficient and necessary conditions in which all objects in Grothendieck categories have injective preco- vers and injective covers.The main results are generalizations of Enochs and Teply. |
