Study on Some Problems of Chaotic Time Series Analysis and Its Application;

According to the closing nature frequency method,a new way to determine the embedding state dimension in the analysis of chaotic time series is provided in the paper.

The method of determining predictable size of chaotic time series based on maximal Lyapunov exponent is deeply analyzed, and its defect is also pointed out.
