本文提出了一个描述受主掺杂铁电陶瓷中由于缺陷随时间的重新取向而引起的材料性能老化的定量模型。通过这种重新取向，畴壁被时间依赖性的力夹紧，导致在老化期间观察到的材料性能的降低。该模型的实验证实与钛酸钡和锆钛酸铅陶瓷的老化和去老化测量。
A quantitative model which describes the aging of the material properties in acceptor doped ferroelectric ceramics as a result of the reorientation of defects in time is proposed. By this reorientation the domain walls are clamped by a time dependent force leading to the observed decrease of the material properties during aging. The model is experimentally confirmed with aging and deaging measurements on barium titanate and lead zirconate titanate ceramics.
