摘要
目的了解《中华放射肿瘤学杂志》引文引用规律及该刊情报吸收能力,探讨该刊的文献引用半衰期及肿瘤学专业的核心期刊,发现我国放射肿瘤学研究领域科研人员的文献需求特征,为该学科研究人员查阅文献提出建议。方法采用引文计量分析法按文章发表的时序逐篇统计该刊2001—2004年间各栏目刊载的475篇文章所引用的参考文献。结果引文率为70.5%,篇均引文8.6条,主要的引文类型分别为期刊(91.7%)和图书(7.8%),普赖斯指数41.6%,自引率6.2%。被引用频次前20位的中外文期刊的文献引用量占总引用期刊文献量的57.0%。结论该刊涉猎文献范围广,引文类型以期刊为主,语种以英文文献为主,引文的外文语种结构较为单一,文献引用半衰期逐渐延长,专业人员利用新文献能力有待进一步提高。
