摘要：
A technique based on reduction of order for solving ordinary differential equations is developed to find exact solutions for a generalized KdV-mKdV equation that possesses high order nonlinear terms.The analytical expressions of several types of travelling wave solutions for the equation are obtained in terms of sin,cos,tan,cot,sinh,cosh,tanh,coth and algebraic profiles.It is shown that the wave speed of travelling wave solutions and the coefficient of low order derivative term in the equation are two main factors to determine the change in the physical structures of solutions.
