Abstract：A fully diagonalized Chebyshev dual-Petrov-Galerkin spectral method is proposed for the generalized KdV-Burg-ers equation in a finite region.This method is accurate and effective in the kink wave solution of the numerical model KdV-Burgers equation.The numerical results show the accuracy and efficiency of this method.Compared with the previous algorithm,the new al-gorithm optimizes the calculation process,reduces the amount of calculation,and is simple and easy to operate.
