the particle motion in central potential field are investigated respectively.Based on the manifest symmetry that each
of problem possesses，part of degrees of freedom are decoupled from the full theory and thus the corresponding
effective Lagrangians and effective Hamiltonians are derived.These examples slow the superiority of effective-theory
method in studying classical mechanics.
Key words： effective-theory method; symmetry; decoupling
