In this paper, a finite difference method for a initial-boundary value problem of regularized long-wave equation was considered. A energy conservative finite difference scheme of three levels was proposed. Convergence and stability of difference solution were proved. The scheme needn't iterate, thus, requires less CPU time. Numerical experiment results demonstrate that the method is efficient and reliable.
