针对期刊网络老化速度研究较为薄弱的状况，以CNKI为数据源，通过对图书馆学情报学期刊下载量半衰期的实证分析研究，解读了下载量半衰期的特点，剖析了其与其它期刊评价指标的区别与联系。结果显示：期刊下载量半衰期明显小于被引半衰期和引用半衰期，与被引半衰期之间存在显著的相关性；与期刊其它计量指标相比有其特质与独立性；开展期刊下载量半衰期研究，有利于突破老化研究中引文分析的藩篱，提升期刊评价的时效性，拓展考察范围及促进期刊出版机构主动缩短网络版与印刷版之间的出版时滞，对期刊整体影响力的提升将产生积极影响。

Aimed at the unsubstantial research on aging speed of network periodicals and taking CNKI as data source, the paper interprets the characteristics of half-life period of downloads, and analyses its differences and relations with other periodical evaluation indexes through the empirical analysis research on half-life period of downloads as to library &information science periodicals. The result shows that half-life period of journal downloads are much smaller than cited half-life period and citation half-life period, and there is significant correlation with the cited half-life period among them as well;but compared with other periodical evaluation indexes, there exist its own traits and independence; it avails for the research of half-life periodical downloads to break through barriers in the study of aging citation analysis, to improve the timeliness of periodical evaluation and expand the scope of inspection, and also to promote periodical publishing organizations to take the initiative shortening of the delay between online and print publication, which will have a positive impact on the promotion of overall journal influence.
