The present paper aims at reconsidering the Kapitsa method in the case of rf traps or multipole ion mass filters. Based on this method a couple of invariants of the corresponding motion are derived in some particular cases. The method and the invariants presented here are useful in numerical analyses which investigate of stability of motion that a charged particle develops in nonlinear rf fields
