摘要
对于两个具有任意非零色散系数的弱耦合Korteweg-deVries（KdV）方程，得到一类微扰孤子解及其存在性条件．数值结果表明，弱耦合相互作用仅给未扰孤子对以小的修正，不改变孤子的特性．
By two weakly coupled Korteweg-de Vries equations with arbitrary nonzero dispersion coefficients, the paper has obtained a kind of perturbed soliton solutions and the corresponding existence conditions, The numerical result shows that the weakly coupled interaction only gives small carrections to the unperturbed solitons. The soliton feature is preserved under the perturbafion.
