Abstract
To explain the dielectric properties of relaxer ferroelectrics, the de ficiencies of relaxation models which corresponds to the flip-flopping of polar regions are indicated to compare with the experimental resul ts at low temperature. A resonance polarization mechanism which corres ponds to the breathing of polar region is introduced. It is indicated that the dielectric constant at low temperature is mainly contributed by the resonance polarization.
