摘要:
本文用修正的简单方程法对sine-Gordon方程和广义的变系数KdV-mKdV方程进行求解，并给出了它们的行波解，当给参数取特殊值时，便可以得到相应的精确行波解。
The modified simple equation method is used to construct the exact solutions for the sine-Gordon equation and the generalized variable-coefficient KdV-mKdV equation. Some exact solutions of the hyperbolic function form for the sine-Gordon equation and the generalized variable-coefficient KdV-mKdV equation are derived by the method. When taking special values of the parameters, the exact traveling wave solutions of the equations are derived from the exact solutions.
