用准静态法和共振法测量了20 ~ 300 ℃温度范围内软、硬锆钛酸铅陶瓷的压电系数d（33），-d（31），d（15），g（33），-g（31），g（15）。结果表明，用这两种方法测得的压电系数d（33）、-d（31）和d（15）随温度的升高而增大，而压电系数g（33）、-g（31）和g（15）随温度的升高而减小。在本文中，所观察到的结果进行了讨论的压电响应的内在和外在的贡献。
The piezoelectric coefficients (d(33), -d(31), d(15), g(33), -g(31), g(15)) of soft and hard lead zirconate titanate ceramics were measured by the quasi-static and resonance methods, at temperatures from 20 to 300 degrees C. The results showed that the piezoelectric coefficients d(33), -d(31) and d(15) obtained by these two methods increased with increasing temperature for both hard and soft PZT ceramics, while the piezoelectric coefficients g(33), -g(31) and g(15) decreased with increasing temperature for both hard and soft PZT ceramics. In this paper, the observed results were also discussed in terms of intrinsic and extrinsic contributions to piezoelectric response.
