摘要:
【目的】分析了“近年来”后引用参考文献的发表时间的离散特点、普赖斯指数、半衰基期与“近年来”所指时间段之间的关系。【方法】以2012—2016年发表的208篇出现了“近年来”且有引用参考文献(共计1096条)的化学学科论文为例,利用Origin8.1和Burton-Kebler老化模型对这些参考文献的发表时间进行分析。【结果】引用文献的发表时间有一定的离散分布特点,四分位数间距说明引用文献发表时间集中的时间段为4~7年。“近年来”引用文献的普赖斯指数2012—2014年为50%左右,半衰期为4~7年,2015年的普赖斯指数为69.75%,半衰期为3年。【结论】科技期刊的编辑处理科技论文遇到“近年来”时,需注意“近年来”后引用参考文献的数量、时间和内容的合理性。

Abstract:
[Purposes] The aim of the study is to analyze the data distribution characteristics, Price index, and half-life of publishing time of references after“in recent years” in scientific journals.[Methods] A total of 1096 references after“in recent years”from 208 chemistry papers are studied using Origin8.1 software and Burton-Kebler equation.[Findings] The publishing time of literature referenced “in recent years” have the dispersion characteristics.Four points spacing is range from 4 to 7 years.From the year of 2012 to 2014,Price index and half-life of literature are about50%,4-5 years,respectively.In 2015,Price index and half-life of literature are 69.75%,3 years, respectively.[Conclusions] Editors should pay more attention to number,Mublishing time and content of references after“in recent years” in scientific journals.
Key words:
“In recent years”,
Half-life of literature,
Burton-Kebler equation,
Price index,
Literature obsolescence
