摘    要:针对文献老化问题,介绍了文献老化常用几种数学模型.根据文献4]提出的通用老化模型,在分析其与伯顿一开普勒公式的关系的基础上,提出了一个文献老化的新模型.结合几个实例利用非线性回归进行模型计算,并与伯顿一开普勒公式及其修正式比较,结果表明该算法用于文献老化是可行和有效的,具有一定的应用参考价值.

关 键 词:文献老化  数学模型  半衰期  比较分析

Abstract:For the literature aging problem,this article introduces several mathematical models in common use.According to the general aging model in Reference 4],a new model of literature aging is presented based on the analysis of the relationship between the general aging model and Burton-Kebler equation.The model is calculated by the use of nonlinear regression and compared with the Burton-Kebler equation and its modified equation in combination with several examples.The result shows that the model is feasible an...
Keywords:literature aging  mathematical model  half-life period  comparative analysis
