摘要
The chaotic behaviors of the time series of the breather(soliton)amplitude have been observed experimentally in the shallow water in the trough subjected to parametric exciting vertically.The results predict that the water solitary waves should be described by some chaotic equations in the higher order approximations as well as by the nonlinear Schördinger equation in the first order.
