The application of Benford's law to groud lightning data(Benford定理在地闪数据中的应用)
自然界数据库中的首位非零1~9数字并不等概率出现,其出现概率符合对数分布,即Benford定理.概述了 Benford定理及其适用范围,在研究浙江省闪电定位系统的2007~2012年监测数据时,发现正闪和负闪的每日地闪频次的首位数字占比情况非常符合Benford定理(相关系数分别为0. 995 6和0. 997 9).正闪雷电流幅值的首位数字占比情况与Benford定理相当吻合(相关系数为0.997 9),但负闪雷电流幅值的首位数字占比却与定理的相关性较差(相关系数为0. 704 9),首位数字“1”的占比明显偏低,推测原因可能为负闪的探测效率明显低于正闪,特别是幅值为十几千安的负闪探测效率可...
