在对科技期刊引文的统计分析中,一些作者常常对文献老化规律与泊松(Poisson)分布进行拟合研究,并得出文献规律符合泊松分布的结论.1994年第13卷第5期《情报学报》在《学术讨论》专栏发表了刘文与王庆林合作的文章《科学文献老化规律 Poisson 分布质疑》,对文献老化规律服从泊松分布以及计算文献半衰期的 Pauline 公式提出了否定的见解.这篇持不同见解的文章作者是在对Pauline Brown《The Half-Life of the Chemical Literature》一文中关于化学文献老化规律服从泊松分布及其计算文献半衰期的公式进行了分析,用 X~2法作了检验,于是得出否定结论的.文献老化规律服从从泊松分布以及计算文献半衰期的 Pauline 公式受到我国文献工作者的相当重视,现在刘文等对之提出了质疑,值得文献工作者重视和深入研究.
In the statistical analysis of citations of sci-tech periodicals, some authors often study the fitting laws of aging law and Poisson distribution and conclude that the law of literature complies with Poisson distribution. In 1994, Volume 13, Number 5, Intelligence Journal “published in the column of” Academic Discussion “Liu Wen and Wang Qinglin article” Aging Law Poisson distribution of scientific literature “, the literature obedience Poisson distribution of aging law and the calculation of the literature half-life Pauline formula proposed a negative view of this. The article with different views is based on the Pauline Brown’s ”The Half-Life of the Chemical Literature," a document on the compliance of chemical literature Poisson distribution obedience Poisson distribution and calculation of the literature half-life formula was analyzed using X ~ 2 method The test leads to a negative conclusion.The literature aging law follows the Poisson distribution and the Pauline formula to calculate the half-life of the literature by our country’s literature workers considerable attention, and now Liu Wen et al questioned it, it is worth the attention and In-depth study.
