【Abstract】 Based on a new extended Hirota bilinear form of the(3+1)-dimensional shallow-water wave equation, the solitary wave and interaction solutions of the equation are constructed following the idea of the three-wave method by using auxiliary functions of a specific form, and the physical structure and dynamical evolution of some of the solutions are demonstrated by numerical simulation given suitable parameters.更多还原
