摘要： 在0~14kbar之间的不同压力下,测量了多晶PbMg1/3Nb2/3O3铁电体的介电常数ε在-196℃~50℃温区内随温度变化的关系,并得到了在不同温度下较完整的ε-P关系.

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.
