| 摘 要： | 抽取2005—2006年中山大学公共卫生学院硕士研究生的学位论文共202篇，以其中的148篇MPH学位论文为研究组，54篇公共卫生全日制研究生学位论文为对照组，比较分析了两组学位论文引文规律及信息需求的差异。结果表明，MPH组的引文量及外文文献的引用率均低于全日制组，且引文率及外文文献引用率存在学科间差异；两组引文类型基本一致，但各类引文所占比例不同，普赖斯指数和半衰期也存在差异。建议通过多种方式提高MPH研究生的信息检索技巧、文献吸收能力。

| Abstract: | Two hundred and two postgraduate dissertations in School of Public Health, Sun Yet - Sen University from 2002 to 2006, were divided into research group （148 written by postgraduates at their post） and control group （54 written by full - time postgraduates） to compare the differences in their literature citation patterns and information needs. The results indicate that the number of citations and the foreign literature citation ratio were lower in the research group than those in the control group. There was a significant difference between the number of citations and the foreign literature citation ratio. The types of literature cited by the two groups were basically identical. However, the proportion of citations was different, and there was a difference in Price index and halflife of the literature cited. It is, therefore, necessary to improve the information retrieval tech- niques and utilizing ability of postgraduates at their respective posts by various means. |
