摘要 Based on the concept of adiabatic invariant,the perturbation to Lie-Mei symmetry and adiabatic invariantsfor Birkhoffian systems are studied.The definition of the perturbation to Lie-Mei symmetry for the system is presented,and the criterion of the perturbation to Lie-Mei symmetry is given.Meanwhile,the Hojman adiabatic invariants andthe Mei adiabatic invariants for the perturbed system are obtained.
