在25 ° C、700MPa的压力下，研究了沿[001]方向极化的菱方相Pb [（Zn1 scin3Nb2 scin3）0.91] Ti0.09O3单晶的压电性能。对于横向机电性能，阻抗和相频特性曲线上的压电响应在500MPa以上突然消失。对于纵向的，在共振和反共振频率的曲线的形状的锐度变得更广泛的500 MPa以上，和压电响应迅速降低与p。这种快速抑制的压电响应高于500 MPa被认为是由于减少的贡献剪切模式的基础上的体积收缩引起的静水压力。
Piezoelectric properties of Pb[(Zn1∕3Nb2∕3)0.91]Ti0.09O3 single crystal poled along the [001] direction in rhombohedral phase was investigated under pressures (p) up to 700MPa at 25°C. For the transverse electromechanical property, piezoelectric response on impedance and phase frequency characteristic curves abruptly disappeared above 500MPa. For the longitudinal one, sharpness of shape in their curves at resonant and antiresonant frequencies became broader above 500MPa, and piezoelectric response rapidly depressed with p. Such rapid suppression of piezoelectric response above 500MPa is considered to be due to decrease in contribution of shear mode based on volume contraction caused by hydrostatic pressure.
