Theory of Non-Propagation Solitons Including Surface-Tension Effects

摘要: 本文研究了表面张力对非传播孤波运动的影响,对Larraza和Putterman的理论进行了修正。发现表面张力使孤波横向振动频率范围增大,振幅增高,宽度减小。当表面张力系数a=0时,结果与Larraza和Putterman的理论相一致。

Abstract: In this paper, the surface-tension effects to non-propagating solitons is studied. Thus the Larraza and Putterman's theory has been modified. It is found that the surface-tension makes the frequency range of crosswise Oscillation of solitions larger, the amplitude higher and the width smaller. When the surfacetension coefficient is equal to zero (α=0), the results are consistent with those of Larraza and Putterman.
