摘要：An analysis of the thematic categories of the reported references in the scientific literature of the Mexican physics in the period 1990-1999 was made, with the purpose of determining the thematic lines of influence of the area at the moment of its greatest growth. Two modules were used: one of references and another of JCR thematic categories and the PACS classification system. Two different situations were found: on the one hand, in quantitative terms a clearly endogenous pattern of influences, strongly dependent on central literature of the area and, on the other hand, according to the diversity of thematic areas, a rising pattern of influences for the decade of the nineties.
