20世纪70年代以来生物化学文献量的动态分析

Kinetic Analysis on the Amount of Biochemistry Documents After 20th 70s'

通过1972—2000年CA中所摘录的生物化学文献量以时间为单位的动态分析,对该学科近30年的发展情况进行了讨论,认为该学科在文献数量上经历了线性增长—停滞—线性增长三个阶段,在部分年份存在幅度较小的波动,在不同的小学科上发展情况有较大差异。

By a Kinetic analysis of the amount of biochemistry documents in CA from 1972 to 2000, this paper makes a study of the development rules in biochemistry amory 30 years. It indicates that the docaments have three changing steps : Line increasing, stopping and ling increasing. The amount of biochemistry documents have little rang fluctuation in some years and large difference in the little subjects development.
