【摘要】：本文以四川省卫生厅及其下属卫生机构所主办公开发行的４种医学期刊１９９０～１９９３年发表的全部论文所附１１６２４条引文为统计对象。对其时序分布，最大引用年限，衰减系数等指标，应用数理统计方法进行了量化分析。结果表明，，我省医学工作者引用１０年内发表的文献占引文总量的７４．７３％，平均衰减系数为３７．１４％；中、外文文献最大引用年限分别在其发表后的第４年和第６年前后，中、外文引文半衰期分别为４．２９３１年和５．７２６２年。
[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.
