摘　　要：引入绝对D-纯模的概念,并讨论了绝对D-纯模类对直和、D-纯子模、扩张的封闭性;研究了D-纯平坦模和D-纯内射模的关系与性质.The concept of absolutely D-pure modules is introduced, and the properties of absolutely D- pure modules are studied, that is, the class of absolutely D-pure modules is closed under direct sums, D- pure submodules and extensions. It is shown the properties of D-pure injective modules and the D-pure flat modules.

关 键 词：绝对D-纯模 D-纯平坦模 D-纯内射模
