[Abstract]:In this paper, 11624 citations of all the papers published from 1990 to 1993 in four kinds of medical journals sponsored by Sichuan Provincial Health Department and their subordinate health institutions are taken as statistical objects. The time series distribution, maximum citation years, attenuation coefficient and so on are analyzed quantitatively by means of mathematical statistics. The results showed that the literature published within 10 years by medical workers in our province accounted for 74.73% of the total citations, and the average attenuation coefficient was 37.14%. The maximum citation years of Chinese and foreign literature were about 4 years and 6 years after their publication. The half-lives of Chinese and foreign citations were 4.2931 and 5.7262 respectively.
