期刊引用半衰期是衡量期刊文献老化速度的指标之一。本文通过对我国五官科学三个子学科耳鼻咽喉科学、眼科学及口腔科学的期刊引用半衰期进行了计算与分析,以此研究我国五官科学文献老化情况。文章采用CMSCI收录五官学期刊引用数据,计算相关期刊的引用半衰期。分析得出结论:五官科学各期刊的每年期刊引用半衰期集中在5至6年之内,其中,偏向于实践的期刊,其引用半衰期要短于偏向理论的期刊,文献老化速度较快,总体上看期刊引用半衰期逐年增加,五官科学发展开始趋于成熟。
Journal citation half-life is one of the indicators to measure the aging rate of journal literature. In this paper, we calculated and analyzed the half-lives of the cited papers of ENT, Ophthalmology and Stomatology in the three sub-sciences of ENT in order to study the aging of ENT documents in our country. The article uses CMSCI to collect the reference data of the five-functional journals and calculate the reference half-life of the related journals. The analysis concluded that the reference half-life of each periodical in the five-year science journals concentrated within five to six years. Among them, journals that tended to practice tended to be shorter than half-life journals, and the literature was aging at a faster rate. On the whole, Look at the journals cited half-life increased year by year, the development of facial features science began to mature.
