【摘要】The perturbation problem of symmetries for the holonomic variable mass systems under small excitation is disrncussed. The concept of high-order adiabatic invariant is presented, and the form of adiabatic invariants and the rnconditions for their existence are given. Then the corresponding inverse problem is studtied. Finally an example is rnpresented to illustrate these results. 【总页数】5页(721-725) 【
