摘　　要：叙述热释电材料居里点的一种自动测量装置，它基于铁电体居里点在ε－Ｔ关系曲线上显示峰值的原理，将振荡信号通过可变温的被测样品，经放大，相敏检波，Ａ／Ｄ转换，由微机给出ε－Ｔ关系曲线及居里点Ｔｃ值。这一装置已用于出口ＴＧＳ系热释电材料的批量检测工艺线上，经美国用户送交美国标准局（ＮＢＳ）复测，样品数据得到认可。本装置还可用于测量其他铁电材料，如ＰＺＴ等。Based on the theory that the Curie point is at the peak of the ε-Tdependence curves, an apparatus has been developed to measure the temperature ofpyroelectric materials, including PZT. This apparatus has been used in the production lineof TGS materials as testing equipment The measurement results get the approval of USNational Bureau of Standards.
