运用经典对称方法解决广义四阶色散方程问题,得到对称约化和群不变解,包括双曲函数解,三角周期解和孤立子解,最后得出该问题的守恒律。
By applying the direct symmetry method to a generalized fourth-order dispersive equation,the symmetry reductions,group invariant solutions of this equation were obtained,which included hyperbolic function solutions,trigonometric function solutions and soliton solutions.At last,the conservation laws of this equation were given.
