摘　　要：构造由Ding-投射模构成的特殊同伦范畴,并给出其性质.此外,若环R满足一定条件,给出该同伦范畴中稳定的t-结构及其对应右的Recollement.We constructed some special homotopy categor ies composed of Ding-projective modules,and gave some properties of them.In addition,if ring R satisfied certain conditions,we gave a stable t-str ucture and its corresponding right Recollement in the homotopy categories.

关 键 词：Ding-投射模 稳定的t-结构 右的Recollement
