| 摘 要： | 基于KdV方程的较低级的两个守恒量——动量和质心,重新研究了近可积KdV物理系统中扰动对单孤子解的影响,导出了单孤子参数演化的一般方程,最后对耗散效应作了讨论.

| Abstract: | Based-on the two lower conserved quantities of KdV equation, momentum
and mass-center, the influence of perturbation on single-soliton solution in nearly integrable KdV physical systems was re-investigated. The evolution equations for the single-soliton parameters were obtained and the dissipative perturbation effects were discussed. |
