摘要：
The electromechanical performance characteristics of electrostrictive 0.9 Pb(Mg1/3Nb2/3)O-3-0.1 PbTiO3 and piezoelectric 0.7 Pb(Mg1/3Nb2/3)O-3-0.3 PbTiO3 ceramics have been investigated under uniaxial stress (sigma). The results demonstrate that the large-signal electromechanical properties of electrostrictive ceramics are decreased with increasing sigma, whereas those of the piezoelectric are increased but accompanied by significantly increased hysteretic losses.
