| Abstract: | 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. |

| Keywords: | harmonic sequence numbers subsequence numbers finite rational numbers equivalence classes |
