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.
