摘 要: 具有vanderPol边界条件的一维波动方程是一种最简单的可能产生迷向或非迷向混沌振动的模型。用混沌振动理论刻画非迷向混沌振动。给出了空间区间上的snapshots在长时间水平线上关于2个参数的变化一个更大有界变差增长区间,改进了已有的结果。 The one-dimensional linear equation with a van der Pol nonlinear condition is one of the simplest models that may cause isotropic or nonisotropic chaotic vibrations. Nonisotropic chaotic vibration by means of the total variation theory is characterized. A larger regime on the growth of the total variation of the sanapshots on the spatial interval in the long-time horizon with respect to two parameters is given which sharpens the corresponding results by Huang.
