摘要: Abstract : In this paper, we numerically investigate the unified Kadomtsev-Petviashvili (uKP) equation derived by Chen & Liu (1995), which described weakly nonlinear and dispersive surface interfacial waves propagating primarily in longitudinal direction of a slowly rotating channel with varying topography on propagation solitary wave stationary Kelvin channel. We find that absence rotation, an oblique incident over three-dimensional shelf straight wide will eventually develop into series uniform straight-crested waves, together train small oscillatory upstream; proper phase shifts, shapes these final two-dimensional coincide those emerged from corresponding normal shelf. two-layered channel, variation does not have much effect depression, whereas it can significant influence elevation. Explanations for numerical findings are given. (AN)
