摘要：

Self-adjoint theorem is introduced to match the corresponding functional of the given differential equations, and then Noether's theorem is used to determine the extended conservation laws of the original equations. Finally, as the application of the method, the conservation laws of Drinfel'd-Sokolov-Wilson equation and Benjamin-Bona-Mahony equation are constructed.
