摘　　要：用纯子群刻画并讨论了Abel群同态扩张的条件,给出了同态扩张的惟一性条件,并讨论了Abel群的矩量问题有解的条件。A condition of extension of homomorphism of Abelian groups is given by using pure subgroups,and the uniqueness of extension of homomorphism is discussed.Furthermore,a condition for solvability of the moment problem of Abelian groups is obtained.
