摘要 研究了带正负指数的(2+1)维Boussinesq水波系统,运用正余弦拟设方法计算出了具有不同物理性质的确切解,并指出了影响解物理结构变化的主要参数. This paper deals with a two-dimensional Boussinesq water system with negative and positive exponents. We use the sinecosine ansatz to get exact solutions of different physical structures such as compactons, solitary patterns, solitons and periodic solutions. It is shown that the physical structures are directly dependent of the main coefficients present in the Boussinesq system.
