摘要: 利用带阻尼参数激励的一维双原子非线性耦合摆阵，实验上观察到局域孤子的摆幅随激励参数的变化，而呈现稳定的、准周期的、周期的或随机的现象，并在理论上用一个五次非线性Ｓｃｈｒ?ｄｉｎｇｅｒ方程来解释

Abstract: Using a one-dimensional damped and parametrically driven diatomic nonlinear coupled pendulum lattice ,we find for the first time in the macro-experiment that the amplitude of localized soliton is stable, quasiperiodic, periodic or random depending on the driven parameter. Theoretically, these experimental results can be explained by the solution of a quintic nonlinear Schr?dinger equation.
