摘要
A 2-D KdV equation of two-layer stratified o-cean with 2-D topography isrecapitulated in the present paper. Based on a reduced version of this 2-D KdV equation, the fissionlaws of the initially internal solitary waves are studied by means of numerical calculation. Fromthe numerical results , it is shown that the initially interface solitary waves can fission on thecontinental slope like the initially surface solitary waves and the fission process is a significantgenerating mechanism of internal interface soliton packet on the continental shelf.
