摘　　要：利用直接积分方法将广义KDV-MKDV方程化为一阶变系数非线性常微分方程组,然后用待定系数法确定相应的常数获得了广义KDV-MKDV方程新的精确解;利用先作假设变换后选取试探函数的方法来直接构造广义KDV-MKDV方程新的精确解.Using direct integration method generalized KDV-MKDV equation was converted the equation into a first-order nonlinear ordinary differential equation,then some new exact solutions were got using undetermined coefficient method,the exact solutiobns were also got using the method that,the assumption transformation was firstly done,then trial function was selected.The result by making the assumption that the use of trial function.
