| 摘 要： | 肌电信号的检测与分析对于临床诊断和康复工程具有重要的现实意义。从生理学角度上讲各种动作是肌肉的收缩产生的,同时伴有肌肉内部各运动单位电位的变化产生了肌电信号。通过对肌电信号一维时间序列的研究,发现其具备一定的混沌特性。信息熵是一个信息量的概念,在重构后的二维相空间中计算了各种肌电信号的信息熵,并对所得结果进行分析,确定了肌肉与动作之间的规律,此规律能为假肢的研究提供科学依据。

| Abstract: | The detection and analysis of surface electromyogram(sEMG) are important in the clinic diagnose and recovering enginedring.In physiology,sEMG was generate by the shrink of muscles,which is associated with the changing of voltage.Through the reconstruct of the sEMG signal discover,it has chaos character.The sEMG information entropy is calculated in two-dimension space.The rules between the muscles and actions are established,which could afford science foundation to the investigate of artificial limb. |
