论文在期刊中分布规律的低频公式

Low Frequency Law of the scattering of articles

本文重点对布拉德福定律中Ｇｒｏｏｓ下垂问题进行了研究，并首次给出了一个描述论文在期刊中分布规律的低频公式。本文的工作包括三个部分：１）对布拉德福定律与布拉德福统计数据（１９３４）的吻合情况进行了检验，指出布拉德福定律与布拉德福数据之间存在的明显差异；２）作为本文的重点，给出了一个描述论文在期刊中分布规律的低频公式，并用布拉德福（１９３４）和Ｐｏｐｅ（１９７５）给出的经典统计数据进行了验证，证明了公式的正确性；３）将本文提出的低频公式应用于对布拉德福统计数据的修正，并通过计算表明，利用本文给出的低频公式修正后的布拉德福数据同布拉德福定律的图象描述取得了高度的一致，证明了本文低频公式的应用价值。

The Groos' drop of the scattering of articles on a given subject among journals is studied in this paper. A low frequency law of the scattering of articles is presented. First, by the examination of the data, it has shown that Bradford's law does not fit Bradford's observed data well. Second,a low frequency law of the scattering of articles is presented and confirmed by the examination of the typical data given by Bradford in 1934 and by Pope in 1975. Finally,Bradford's observed data is modified by the new low frequency law,and the examination shows that modified Bradford's data fit Bradford's law remarkably well. This shows that the low frequency law of the scattering of articles is quite effective and applicable.
