摘　　要：根据非线性动力系统理论 ,对纱条不匀数据中的混沌特性进行了分析 ,在对其不匀序列进行相空间重构的基础上 ,通过对关联维数的逼近及最大李雅普诺夫指数的计算 ,得出在所分析的棉条不匀序列中 ,存在混沌现象。The chaotic phenomenon in terms of the observation time series of yar n evenness was studied. According to nonlinear dynamical systems(NDS ) theory, e vidence of chaotic behavior was searched:the correlation dimension and the large st Lyapunove exponent extracted was gotten from a single observed time series. The result shows that chaos exists in the series of yarn evenness which exhibit very differ ent character from white noise series.
