摘要
为了提高文献增长和文献老化模型的拟合精度,采用级数模型的方法,得出了文献增长和文献老化的级数模型,相对于原有的文献增长和文献老化模型,级数模型的拟合精度高.
In order improve the fitting accuracy between the literature growth and the literature aging model, the series model of literature growth and literature obsolescence is obtained by this paper with the method the series model. Series model fitting is higher precision, as opposed to the original document growth and literature obsolescence model.
