摘　　要：引入Gorenstein弱内射复形,研究Gorenstein弱内射复形的同调性质,并给出了Gorenstein弱内射复形的等价刻画。讨论复形的弱余合冲与Gorenstein弱余合冲之间的关系。The notion of Gorenstein weak injective complexes is introduced,and some homological characterizations of Gorenstein weak injective complexes are given.Moreover,the relationship between weak cosyzygy and Gorenstein weak cosyzygy of a complex is discussed.
