| 摘 要： | 表面肌电信号是肌肉收缩时的电变化在皮肤表面的综合反映，根据表面肌电信号（ＥＭＧ）属于短数据量的时间序列的特点，提出了利用替代数据方法对ＥＭＧ信号的动力学特性进行了分析，研究表明，ＥＭＧ信号是非噪声的确定性信号，并具有确定性的非线性特性，为进一步分析其混沌动力学特性提供了客观依据。

| Abstract: | The surface electromyograph(EMG) signals (SEMGs) are a complex interference pattern of the electrical activity during muscle contraction. Since the surface EMG signals are short time series, it was proposed using the surrogate data to analyze dynamic property of EMG signal. The results show that EMG data is non noisy and has determinate nonlinearity. This paper provides an objective basis for the further analysis of chaos dynamic feature of the surface EMG signal. |
