摘　　要：引入了n-强丁投射模的概念,它是强丁投射模的推广.研究了这种模类的同调性质,并讨论了当m≠n时,m-强丁投射模和n-强丁投射模的关系.The notion of an n-strongly Ding projective module was introduced,which is a generalization of the strongly Ding projective module.The homological behavior of n-strongly Ding projective modules was investigated and the relation between m-strongly Ding projective modules and n-strongly Ding projective modules were studied whenever m≠n.
