Abstract: The contradictory between experiments and theory about the effect of the surface tension on the non-propagating soliton was discussed in this article. Since the lateral wave length was short, the effect of the surface tension on the non-propagating soliton was discussed by Miles and Zhou. They modified the relation between the frequency and the wave length by the surface tension, and brought it into higher order. According to the theoritical analysis, Zhou divided the kh-σ plane into three regions (Fig.1), ...
