AN IMPROVED ALGORITHM FOR EARTHQUAKE SERIES MULTIFRACTAL SPECTRUM
【摘要】 通过分析地震记录多重分形谱的不同计算方法,引入一种新的多重分形概率测度概念,同时也提出了一种时间序列多重分形分析的改进方法。该方法具有计算量小、计算时间短的特点,并同时也可以快速、有效地求出地震记录的多重分形谱。
【Abstract】 By comparing several general multifractal spectrum algorithms,a new definition of multifractals probability measure is introduced and an improved algorithm of time series multifractal analysis proposed.The a1gorithm can save computation and time. Using this algorithm we can compute multifractal spectrum of earthquake series quickly and effectively.
