Abstract  This paper analyzes the symmetry of Lagrangians and the conserved quantity for the holonomic non-conservative system in the event space. The criterion and the definition of the symmetry are proposed first, then a quantity caused by the symmetry and its existence condition are given. An example is shown to illustrate the application of the result in the end.
Keywords:  symmetry of Lagrangians      event space      holonomic nonconservative system      conserved quantity
