| Abstract: | The behaviour of the dielectric constant s of polyerystal ferroelectric PbMg1/3 Nb2/3O3 was measured in the temperature range -196℃-50℃ at the different pressures and the ε-P relation was obtained. The results were analysed by the statistical model of diffuse phase transition and the effect of pressures on diffuse phase transitions was discussed. |
