摘要In this paper,the I-ring which satisfies almost descending chain conditions(shorten writting A.D.C.C)on principal left ideals is studied.Two main results are gaven:(1)I-ring which satisfies A.D.C.C on principal left ideals is Boolen.(2)Ring with identity whose principal left ideals satisfy A.D.C.C and of which each element except identity is a left zero-divisor,is Boolean.These results generalize the results of[1],[2]and[3].
