本统计分析依据2010~2012年版的《中国学术期刊影响因子年报(自然科学与工程技术)》提供的统计数据,分析了中国核科学技术类12种期刊2008~2011年间的变化趋势。首先对比了期刊的基本信息和收录情况,然后对其影响因子、总被引频次、可被引文献量和即年指标进行了综合分析。结果显示,核科学技术类期刊整体国内影响力较高,但国际竞争力需提升,平均复合影响因子(U-JIF)为0.413、平均综合影响因子(MS-JIF)为0.279,但他引影响因子与平均影响因子位次有所不同,说明存在自引率偏高的情况,绝大多数期刊的总被引频次呈逐年上升的趋势,但各期刊的总被引频次相差悬殊,总被引频次与可被引文献量呈正比关系,需进一步提升刊物的国内国际影响力。统计分析结果对提升上海应用物理所的刊物水平有所帮助。
The statistical analysis is based on the statistical data provided in the 2010-2012 edition of the Annual Report of China Academic Journals Impact Factor (Natural Science and Engineering), and the trend of changes in China’s nuclear science and technology 12 journals from 2008 to 2011 is analyzed. First of all, the author compares the basic information of the periodicals and their collection status, and then makes a comprehensive analysis of their influence factors, the total number of cited cites, the amount of citing documents available and the immediate indicators. The results show that the nuclear science and technology journals generally have a higher domestic influence but their international competitiveness needs to be improved. The average composite impact factor (U-JIF) is 0.413 and the average comprehensive impact factor (MS-JIF) is 0.279. However, The rankings of factors and average influence factors are different, which indicates that there is a high self-cited rate. The total citation frequency of most journals tends to increase year by year. However, the total citation frequency of each periodical differs greatly, It is necessary to further enhance the domestic and international influence of publications in proportion to the amount of quoted documents. Statistical analysis of the results of the Shanghai Institute of Applied Physics to help improve the level of publications.
