摘要
本文对文献[2]中绘出的科学文献老化规律服从Poisson分布的结论进行了讨论,分析结果表明,科学文献老化规律服从Poisson分布的结论是不能成立的,因此在此基础上给出的计算文献半衰期的Pauline公式亦不能成立。本文对文献[2]给出错误结论的原因进行了分析。
The conclusion that the average citation per article in chemistry by ageof citation is ielated to the Poisson frequency distribution,given by Pauline in reference[ 2] ,is discussed,The X2 test shows that Pauline’s law is incorr-ect,Therefore,the formula for calculation of a half-life for chemistry which based on the former conclusion is also incorrect,The cause which led the in-correct conclusion in reference[ 2] is analyzed.
