摘　　要：在文献[1]的基础上,给出了任何给定的有限正有理数均可用调和数列收敛子数列表示的必要条件,并在给出等价关系的情况下,对必要条件进一步讨论.Based on reference [1], this essay deduces the necessary condition of any finite positive rational numbers can be represented by a convergence subsequence of harmonic sequence numbers. With the equivalence relation, it also takes further discussion for the necessary condition.
