中文摘要:
      本文引进分次直投射模的概念,得到分次直投射模的一个判定定理,并利用分次直投射模刻划了分次左遗传环,分次左半遗传环,分次左半单环和分次左PP-环,
英文摘要:
      In this paper, we introduces the concept of graded direct projective modules, ob-tains a critical theorem of graded direct projective modules and characterize graded(left) hereditary rings, graded(left) semihereditary rings, graded(left) semisimple rings and graded(left) pp-rings via graded direct projective modules,
