A nonlinear constitutive model for piezoelectric ceramics is proposed, in which the polarization switching and electricsaturation are taken into account.
提出了一个简单的包含有极化反转及电饱和影响的压电材料的本构模型。

The variation of CHGR with depth is available from the calibration of the porosity, gas saturation of electric log interpretation of the reservoir and hydrocarbon gases expansion coefficient.
This article studies the change of threshold voltage and saturation voltage affected by external electric field with the change of various parameters such as anchor strength, elasticity coefficient.
