在空间分立点加时间周期信号控制时空混沌,以一维非线性漂移波方程为模型 ,讨论了其时空混沌运动的控制.研究表明 ,通过在空间分立点加上自然频率的时间周期信号 ,可以控制时空混沌运动.这种方法较之在连续空间加周期信号的方法 ,在有些系统中 ,实验上更容易实现-Discrete point in space plus time cycle signal control spatiotemporal chaos to one-dimensional nonlinear drift wave equation as a model to discuss its spatial and temporal control of chaotic motion. Studies show that the separation in space combined with the fact that the natural frequencies of time periodic signal, spatiotemporal chaos can be controlled movements. This approach than in the continuous space plus periodic signal method, in some systems, easier to realize experimentally
