This paper makes statistical analysis on the published papers quantities, authors, quotations, paper publishing time lag and other materials of Journal of Information Theory and Practice in period of 2001-2004, and sums up the features of the papers published in this journal. 统计和分析了2001&2004年期间《情报理论与实践》的载文量、作者、引文、论文出版时滞等资料,总结了该刊的载文特点。
The measurement with step voltages, using CIGRE ⅱ electrode system, showed that the statistical distribution of the discharge time lag depends on the applied voltage, the time lag being shorter with increasing voltage. 实验结果显示放电时延的统计学分布与外施电压有关,电压增大,时延缩短。
The Statistical Method of Average Cumulative Inclusion Lag, a method for the statistics of database inclusion time lag, can be used easily for the statistics of cumulative lag in a long period of time, and eliminates errors caused by short statistical period in manual sampling. 平均累积报道时差统计法用于数据库报道时差的统计,可快捷精确地统计较长年限的累积时差,消除了手工抽样统计由于统计年限较短带来的统计误差。
In this paper, this kind of nonlinear characteristics was analyzed by using the BDS statistical analysis method and the nonlinear time lag correlated character determination method. 采用BDS统计分析和非线性时滞相关性判定法,研究这种非线性特性。
