摘要: 本文是讨论一类时滞非线性扰动长波系统的孤波解。首先,引入非扰动的典型长波方程的精确解。然后,用同伦映射和改进的技巧构造了非线性扰动时滞长波系统孤波行波解的近似展开式。Abstract: The solitary wave approximate solutions for a class of nonlinear-disturbed time delay long-wave system are con-sidered. First, we introduce into exact solution of a non-disturbed typical long-wave system. Then, by using the homotopic mapping and an improved technique, the approximate expansions of the traveling wave solutions for the nonlinear-disturbed time delay long-wave systems are constructed.
