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.
