corrosion of mass- spring. Based on this model，we further solve the adiabatic invariant in the

case of slow corrosion of electrolyte liq- uid in parallel plate capacitor. The mathematical

methods and physical ideas in the process provide a feasible direc- tion for the quantization of

classical physics. In addition，the model can also be simply extended to the adiabatic in- variant

in the case of magnetic medium degradation.
