| 摘 要： | 根据期刊影响因子的定义,分析了影响期刊影响因子的相关因素。然后基于时间和专业因素对影响因子的影响,利用新兴学科的期刊文献引用量在一段较长时间内呈现短期内快速增长并到达一个顶峰、之后呈现逐年下降趋势的特点,建立了期刊发行期内基于W eibu ll分布的扩展影响因子模型。最后结合R因子和两年期刊影响因子对JCR中的8种生物类期刊进行了实证研究。

| Abstract: | The aspects which affect impact factor(IF) are discussed based on the definition of IF in this study.Citation vintage and subjects as important aspects of impact factor are emphasized.Based on the theory of Weibull distribution and the characters of the times of citation that increase quickly to the top in a long period of time and then decrease yearly,an extended impact factor model is established in issue periods.And then,an empirical study of eight journals on biology from JCR is launched compared with R... |
