摘要
从分形和混沌理论出发,应用VB程序设计语言,设计了混沌时间序列的吸引子关联维和Kolm ogorov熵的计算机算法,并以黄河花园口断面年平均径流量时间序列资料为例,具体进行了计算。结果表明,该算法具有较强的时效性和可操作性,可作为一般的分析工具应用于复杂系统时间序列的混沌分析。
An algorithm is described for using fractal and chaos theory to analyze the nonlinear time series. The related fractal and chaos theory are introduced first, then use Visual Basic program language is designed to calculate the attractors＇ correlation dimension and timeseries Kolmogorov entropy. Then, with the example of the annual average runoff time series at Huayuankou section of the Yellow River, results obtained by the designed program are presented to test the effectiveness of the proposed method. This approach, therefore, turns out to be of high processing speed and maneuverability, and it can be one of analytical tools for chaos analysis of complex systems.
