The Exact Travelling Wave Solution to(1+1)-Dimensional KdV Equations

The existence of the exact traveling wave solutions of a class of mixed(1+1)-dimensional KdV
equationswas put under examination. Firstly, by introduction of the wave variable, the partial differential equations are transformed into ordinary differential equations. And then, by means of the initial integral method, the solution to the ordinary differential equation is obtained. And therefore, the exact traveling wave solutions to the mixed(1+1)-dimensional KdV equations are worked out.
