【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。
【Objective】 The paper analyzes the relationship between the discrete characteristics of published references after the “recent years”, the Price index, the half-decay period and the time period in recent years. 【Method】 A total of 208 published papers published in the period of 2012-2016 in “recent years” with cited references (1096 in total) were used as examples to analyze these references The publication time of the literature was analyzed. 【Result】 The publication time of the cited documents has a certain discrete distribution. The interquartile range shows that the time period for the publication of the cited documents is 4-7 years. The Price Index cited in recent years is around 50% from 2012 to 2014 with a half-life of 4 to 7 years. In 2015, the Price Index was 69.75% with a half-life of 3 years. 【Conclusion】 When the scientific and technical journals of sci-tech periodicals encounter “recent years”, attention should be paid to the rationality of quoting the number, time and contents of references in recent years.
