摘要
简要分析高校图书馆借阅集中与分散现象的原因,通过实例统计数据对布鲁克斯公式的回归,证实高校图书馆借阅集中与分散十分类似于文献分布定律。最后对该规律作详细归纳与总结,引入核心系数(λ)与未用系数(δ)概念,结合实例讨论合理的λ与δ的取值范围,并进一步讨论根据核心区与外围区或未用区确定复本的方法。
The paper briefly analyzes the phenomenon of concentration and decentralization of borrowing books in college libraries and proves that it is similar to the document distribution law through finding that the counting data is the regression of the Brookes Equation. The paper further makes detail conclusions about this rule and introduces the concepts of core region（λ ）and unused region（ δ ）. It also discusses the reasonable value range of λ / δ with examples, and gives the methods which can ensure the number of duplicates according to the core region, external region and unused.
