摘　　要：讨论群G上的幂半群Г，即以G的非空子集为元素，在G的集的乘法运算下所成的幂半群。给出了Г是G的一个正规子群列的正规子群的陪集的集合的条件。Let Г be a power semigroup on a group G, that is all elements of Г are sub-sets of G and the operation is subset product of G. In this paper, We gave the condition of Г is set of quotients of normal groups in a normal series of G.
