| 摘 要： | 本文研究了基底具有线性波动的流体表面波,着重分析了线性波对表面孤波的影响.在基底线性波为长波、小振幅条件下,利用多重尺度摄动方法导出了流体表面波满足的基本方程.结果表明,在二级近似下,流体表面出现与基底波动同频率的简谐波以及传播KdV孤立波,该表面简谐波与传播孤立波互不干扰,各自独立传播。

| Abstract: | Using the multiple scales perturbation method,the author studythe long, weak nonlinear solitary waves on the surface of the fluid witha harmonic wave on the bed.Results under the two-order approximationshow that there are solitary waves and a harmonic wave on the surfaceof the fluid and they propagate independently. |
