为了描述耦合映象格子(CML)的冻结化随机图案模式,定义和计算了与格点位置相关的李雅普诺夫指数谱,并和由雅可比矩阵乘积计算的李雅普诺夫指数谱做了比较.对格点扰动传播过程的研究表明,这种李雅普诺夫指数谱能很好地描述耦合映象格子在随机化冻结图案模式下的时空动力学行为.

The spatiotemporal dynamical behavior of frozen random pattern modes of coupled map lattice(CML) is investigated .The space-related Lyapunov exponent spectrum is defined and calculated from perturbations to each site for various perturb intensities and compared with that obtained from the products of Jacobean matrices.The diffusive process of a single site perturbation shows that the space-related Lyapunov exponent spectra can well characterize the spatiotemporal dynamic behavior of the frozen random pattern mode of CML.
