摘要
为了模拟方志类文献老化过程,本文对几种常见文献老化模型进行了比较,并结合志鉴类文献实际情况,最终在莫地列夫公式和丁学东公式的基础上,提出新的老化模型——"丁—莫"修正式,并给出其回归分析的具体解法。
This article is intended to simulate obsolescence of regional documents.By comparing several common literature aging models,combined with the actual situation of regional documents,this article proposed a new obsolescence model——＂D-M＂modified equation,which was based on Мотылев equation and Ding Xuedong equation,and gives out the specific solution of the regression analysis.
