通过中国知网学术文献总库和中国知网引文数据库,获取我国6个学科30种期刊2000年发表的论文在2000~2009年各年度的被引量,确定国内科技期刊论文被引量的峰值年代。获取2005年发表的论文在2005~2009年各年度的下载量,确定国内科技期刊论文下载量的峰值年代。结果显示:从我们统计的6个学科期刊来看,5个学科期刊的被引量峰值年代在论文发表后第8年(2000年为当年,2001为第2年),只有临床医学类期刊在论文发表后第7年。关于论文下载量的峰值年代,6个学科期刊论文下载量的峰值年代全部在论文发表后的第2年。因此,我们认为,我国科技期刊论文被引量的峰值年代在论文发表后的第7-8年,绝大部分期刊在论文发表后第8年;论文下载量的峰值年代在论文发表后第2年。
Through the China National Knowledge Infrastructure and Chinese Knowledge Citation Database, we obtain the quoted quantity of the papers published in 2000 from 30 kinds of journals in 6 disciplines of our country in each year from 2000 to 2009, and determine the quoted peak of the papers of domestic scientific journals Age. Obtain the number of papers published in 2005 in each year from 2005 to 2009, and determine the peak age of papers published in domestic science and technology journals. The results show that from the six subject journals we counted, the top five cited journals of the five subject journals are the eighth year after the publication of the essay (in year 2000 and the second year in 2001), only journals of clinical medicine in The seventh year after publication. In the peak years of the dissertation downloads, the peak years of the dissertation downloads of the six dissertations were all in the second year after the dissertation was published. Therefore, in our opinion, the peak times of citations of papers in Chinese scientific journals are the 7th to 8th year after the papers are published, the most of the journals are in the 8th year after the papers are published. The peak age of paper downloads is the second year.
