【Abstract】 This paper discusses the algebra structure of the set of Positive reciprocal metrices,It asserts that the set of positive recip-rocal metrices is a Abelian group’that the set of uniformly positive reciprocal metrices is a invariant subgroup of the set of positive reciprocal metrices,aud that the set of positlve reciproCal metrices is the direet product of the set of uniformly positive reciprocal met-rices and tho set Of standard positive reclprocal metrices.更多还原
