利用齐次平衡法推导出二维色散长波方程组的Backlund变换,并根据Backlund变换构造出4种精确解,其中包括多孤子解、双曲函数和指数函数混合型解、三角函数和指数函数混合型解等.
In this paper, the Backlund transformation to the (2+l)-dimensions nonlinear dispersive long wave equation is derived by using the homogeneous balance method. And the exact solutions of 4 families are given by means of Backlund transformation, including multi-solitary solutions, the exponential function solutions, the hyperbolic function solutions and the triangular function solutions.
