摘要
为了分析水稻病毒期刊论文被引分布规律,以中国知网《中国学术文献网络出版总库》为统计源,对1963年至2011年间水稻病毒期刊论文进行统计。结果表明:水稻病毒在期刊上累计发表论文1007篇,其中,525篇论文被累计引用4467次;水稻病毒论文被引频次分布存在着明显的集中与分散现象;水稻病毒论文被引频次与论文数量拟合模型不符合幂函数分布、洛卡特规律和齐普夫模型;采用布拉福德定律中较为精确的莱姆库勒模型对水稻病毒论文累积论文数量比值(x)与累积被引频次比值(y)进行拟合得出y=0.2892ln(1+30.7499x),预测值与实际值通过K-S检验,符合布拉福德分布曲线。
In order to analyze the rule of times cited on rice virus periodical papers,data from＂China Academic Journal Network Publishing Database（CAJD）＂from 1963 to 2011 had been statically counted. The results showed that：1007 periodical papers were published,among which 525 periodicals were cited for 4467times; distribution of cited frequency of rice virus periodical papers showed obvious centralization and decentralization; fitting model of cited frequency and quantity of rice virus periodical papers did not meet the power function distribution,law of Luo Kate and Zipf model; Lyme Kule model,the precise model of Bradford＇s law,was fitted to the ratio of cumulative number of papers（x） and the ratio of cumulative citation frequency（y）and fitting result showed as y=0.2892ln（1＋30.7499x）,predicted values and actual values were tested through K-S test,which were in accordance with Bradford.
