摘要
利用Bell多项式和Hirota双线性方法研究了流体力学中广义浅水波方程,得到了广义浅水波方程的单孤子解、双孤子解和三孤子解,以及N-孤子解的解析表达形式.通过多孤子的演化图形,讨论了不同类型的孤子解的性质.
In this paper, via the Bell polynomial and Hirota method,the generalized shallow water wave equation in certain fluids is investigated. The bilinear form, N-soliton solutions analytic expression and B^icklund transformation of the generalized shallow water wave equation are obtained. The one-soliton, two-soliton and three-soliton solutions of the generalized shallow water wave equation are obtained with N-soliton solutions analytic expression. Through graphical analysis, the dynamic features and elastic interactions of different types of multi-soliton solutions for the generalized shallow water wave equation are discussed.
