摘要：
The influences of hydrostatic pressure on the relation between dielectric constant (Εr) and temperature of PMN-PT single crystals have been studied. Dielectric frequency dispersion phenomenon of poled single crystals was observed under high hydrostatic pressure. It has been found from experimental results that the dielectric constant decreases quickly and the dielectric frequency dispersion is more notable when the hydrostatic pressure is higher.
