Abstract: The Gorenstein projective and Gorenstein injective properties of modules over rings were studied. Firstly,under the framework of an Artin ring,the sufficient and necessary conditions for any left R-module to be a Gorenstein projective module and a Gorenstein injective module were discussed by the characterization condition of a special ring. Then,the Gorenstein projective and Gorenstein injective properties of modules over a general ring were described in terms of the embeddability of the right R-module to free Rmodules and projective modules,as well as the zero-dependent lifting chain. The results of the existing literature were partially extended.

Key words: Gorenstein projectivity, lGorenstein injectivity, lQF-ring, Artin ring
