The cyclotron motion of ion in a nonuniform electromagnetic wave is analysed using the multiple-time-scale-expansion method. A set of nonlinear equations which describes the evolutions of the gyroradiusρ, the gyrophase β, and the average velocity <ν_z> along the magntic field B_0 is obtained. The set is found exactly integrable and three conservation relations are obtained for an arbitrary harmonic amongρ, β, <ν_z> and the drift coordinates perpendicular to B_0. The theory includes the one obtained for the fundamental harmonic and a uniform amplitude wave and is also applied to ion acceleration in a non-uniform field near an antenna used in an ion-cyclotron-range-of-frequencies (ICRF) wave heating. Thus the theory seems to be more rigorous and general than the previous ones.
