| 摘 要： | 本文讨论了二流体系统界面上内孤立波的分裂,发现上下层流体密度比对分裂成两个内孤立波的条件没有影响,此时只要孤立波从较深的流体运动到较浅的流体就会发生分裂,但分裂成二个以上孤立波的条件受密度比和上游上下层流体厚度比的影响。

| Abstract: | In this paper, the fission of interfacial solitary waves in a two-layer fluid system is investigated. It is found that the density ratio of the upper and lower fluids has no effect on the fission conditions of forming two solitary waves. It means that the fission may occur provided that solitary wave travels from deeper fluid to shallower fluid. But the fission conditions of forming more than two solitary waves are related to the density ratio and upstream depth ratio of the upper and lower fluids. |
