中文摘要: 应用代替数据法计算振动噪声环境影响下脉搏信号的混沌特性，根据所得到的几个特征参数值对不同振动噪声环境下的脉搏信号进行非线性特性对比与分析；阐述了基于代替数据法的时间序列的混沌特性计算原理，通过实验测量不同振动噪声参数并计算与之相应的脉搏信号，获得了振动噪声参数对脉搏信号特征参数的数值变化及影响规律.

中文关键词: 振动噪声脉搏信号代替数据法特征参数

Abstract:The chaos of pulse wave are identified by surrogate data method.Firstly,the main principle of chaotic identification is introduced,in which the median absolute error (MAE) of one-step prediction for pulse wave is set as the statistic.The algorithm is checked with a known chaotic system response and a colored noise signal.Then,some typical pulse waves under vibration and noise conditions are analyzed by means of surrogate data,and some characteristic parameters from this method are compared.

keywords: vibro-noise environment pulse wave surrogate data method characteristic parameters
