摘　　要：Perturbation to Noether symmetry of discrete mechanico-electrical systems on an uniform lattice is investigated.First,Noether theorem of a system is presented.Secondly,the criterion of perturbation to Noether symmetry of the system is given.Based on the definition of adiabatic invariants,Noether adiabatic invariants of the system are obtained.Finally,An example is given to support these results.
