【摘要】：基于数学、计算机科学、经济学和历史学四类学科期刊样本1980-2009年间发文量与被引量的统计数据,结合SPSS统计工具软件,分析4门学科期刊30年间文献增长的数量特征及其曲线拟合结果,并结合插值被引半衰期与B-K被引半衰期剖析两种文献老化测度指标之间的数量差异,以及两者共同反映出的科学文献老化趋势延缓与学科差异化特征。最后,基于上述分析结果定量化揭示影响文献老化的学科、文献增长、文献介质类型等外部因素及内在机理,以期对当前环境下科技期刊长期老化状况做一个全面客观的认识。
[Abstract]:Based on the statistical data of the samples published and cited from 1980 to 2009 in four disciplines, mathematics, computer science, economics and history, combined with SPSS statistical tool software, The quantitative characteristics and curve fitting results of literature growth in four subject journals during the past 30 years were analyzed, and the quantitative differences between the two indices of literature aging were analyzed by using interpolation citation half-life and B-K cited half-life. The aging trend of scientific literature and the characteristics of discipline differentiation are reflected by both. Finally, based on the above analysis results, the external factors and internal mechanism of the subject, literature growth, literature media type and so on affecting the literature aging are revealed quantitatively, in order to make a comprehensive and objective understanding of the long-term aging status of sci-tech periodicals in the current environment.
