【Abstract】 Symmetry is an important method to find out conserved law in modem analytical mechnics.In the present paper,the authors first introduce the relationship between symmetry and conserved law for mechanical systems.Then we focus on Lagrangian symmetry,including its origin,development,status quo and its promising works discussed in the last section,together with some suggestions on the study of Lagrangian symmetry.更多还原
