摘要
本文分析了科学领域内的文献老化问题和期刊文献出版延时现状,介绍了常用的老化测度,分析了文献发表延时转移到引文年龄分布上的过程,并定义这一转移过程为文献引用延时效应,建立了实际老化过程的传递函数模型,利用引文分析法和数学模拟方法对出版延时对文献老化的影响进行科学计量研究,得出科技文献出版延时延缓科技成果和信息老化和延缓科学发展的结论。
In this paper, the aging of literature and the publication delay are analyzed in the science field. Aging measure methods in common use are introduced. Then the process that the delay is transfered to the aging function is analyzed, and is defined citation delay response. The transfer function model of the aging process is established, based on the model the influence of publication delay on the aging of literature in the science field is quantificationally studied using citation analyzing and mathematical simulating and the conclu- sion is gained that the publication delay postpones the aging of scientific knowledge and science development.
