摘要
本文用多重尺度微扰方法研究了矩形槽中三维不可压缩无旋流体表面波的弱非线性调制,考虑了外加驱动及粘牲对流体运动的影响,修正了Larraza-Putterman方程,得到了与Miles相一致的结果。
The weak nonlinear modulation of the surface wave of a three dimensional im-
compressible fluid without rotation, which is contained in, a rectangular trough is studied by using the method of multiple scales perturbation theory. The effects of viscid and external drive on the motion, which modifies the Larraza-Putterman equation, are considered. The results are consistent with that of Miles.
