Abstract:A class of exact solution to two-dimensional KdV-Burgers equation are abtained by the help of the method of analogy-undeternimed coefficient which involve known results ,These slolutions,generally,cna be expressed by u=uB+бuk--бu,where uB is the solution of 2D-Burgers equation and uk is the solution of 2D-KdV equation.
