弛豫基铁电（1 - x）Pb（Zn（1/3）Nb（2/3））O（3）-xPbTiO（3）和（1 - x）Pb（Mg（1/3）Nb（2/3））O（3）-xPbTiO（3）单晶由于其超大的压电系数和机电耦合系数，给性能表征带来了新的挑战。大的错误可能会发生在一些派生的材料常数使用传统的表征技术。本文将分析传统表征方法的不足，并提供一些基本的指导方针，正确表征压电材料具有极高的压电和机电耦合系数。(C)2002年由Elsevier Science B. V.出版
The relaxor based ferroelectric (1 - x)Pb(Zn(1/3)Nb(2/3))O(3)-xPbTiO(3) and (1 - x)Pb(Mg(1/3)Nb(2/3))O(3)-xPbTiO(3) single crystals provided new challenges in property characterization because their extraordinarily large piezoelectric coefficients and electromechanical coupling coefficients. Large errors may occur in some of the derived material constants using conventional characterization techniques. This paper will analyze the inadequacy of the traditional characterization methods and provide some basic guidelines for properly characterizing piezoelectric materials with extremely high piezoelectric and electromechanical coupling coefficients.
