通过中国知网的引文数据库,获取10个学科门类50种期刊2001年发表的论文在2001～2010各年度被学位论文和期刊论文引用的频次,分析科技期刊论文被学位论文引证的规律。结果表明:从统计的10个学科来看,科技期刊论文被学位论文引用的时滞更长,50种期刊合计在第8年(2001年为当年,2002年为第2年)达到峰值,比被期刊引用的平均峰值年代(5年)延后了3年。学位论文对期刊论文引用的峰值年代学科间差异较小,全部在第7年或第8年。科技期刊论文被学位论文引用的频次从第6年开始超过被期刊引用的频次,所占比例最高时达到59.8%,表明将学位论文作为引文统计源计算期刊的影响因子能更好地反映我国科技期刊的影响力。
Through the citations database of CNKI, we can get the frequency of the papers published in 2001 by 50 dissertations in 10 subject categories in 2001 and 2010, respectively, and analyze the regularity that the dissertations of science and technology dissertations are cited by the dissertations. The results show that the statistics of the 10 disciplines point out that the sci-tech periodical dissertation citation time lags longer, the total of 50 periodicals in the eighth year (in 2001 for the year, 2002 for the second year) peaked The average peak age cited by journals (5 years) was delayed by 3 years. The dissertation disagrees little about the period of peak essay cited in the journal articles, all in the 7th year or the 8th year. The frequency of dissertation dissertation cited by dissertation is more than that cited by journals in period 6, accounting for 59.8% of the total. This indicates that using dissertations as the citation statistical source can better reflect the impact of science and technology Periodical influence.
