布鲁克斯认为用户获取知识的过程遵循对数转换机制。为探究这一理论的一般表现形式，将引文作为主要研究对象，分别从时间、学科对数据挖掘领域的引用文献进行对数规律探析，再从该领域文献的被引用情况，探讨文献使用率问题。结果表明，引文在时间轴上具有明显对数函数关系，本学科或相关度高的学科(领域)文献被引用的比重较高。而经对数转换的文献使用率，能够更好地揭示科研成果在后期科研工作中发挥的作用。%The general law of knowledge obtaining is explained by B. C Brookes, who believes that the process of knowledge acquiring follows the principle of logarithmic perspective. In order to explore the general form of the law, the documents of data mining and their ci-tations being taken as the main way of knowledge acquiring are studied in this paper. Then, time logarithmic perspective of knowledge ac-quiring and subjects or fields logarithmic perspective are analyzed. Besides, the rate of papers utilization is analyzed based on the observa-tion of papers cited after the publication in the field of data mining. As a result, time logarithmic function of citations is showed clearly, higher proportion of related subjects is accounted for, and document usage after logarithmic transformation is found to be more accurate in revealing the role of existing researches to support the future research work.
