Multifractal Analysis of ELF Transient Events Based on MF-DFA

  • 摘要: 利用三个测站实测极低频全球闪电活动背景信号南北及东西方向磁场分量资料, 应用多重分形方法对极低频瞬态事件发生时前1s背景信号中的长程关联性及多重分形特征进行了分析. 发现极低频瞬态事件发生时, 最大脉冲前1s背景信号南北及东西方向磁场均具有长程关联性和多重分形特征. 其中南北方向最小标度指数0.15 < amin< 0.22, 分形谱宽度1.09 < Δa < 1.51; 东西方向最小标度指数0.23 < amin< 0.59, 分形谱宽度0.75 < Δa < 0.99. 多重分形谱参数Δaamin可以很好地自动识别Q-burst发生.
