中文摘要：

与通用测试机器和温度测试房间，在我们的实验室与 PZT/epoxy 准备的 1-3 和 1-3-2 piezocomposites 的行为上的压力和温度的效果通过电的阻抗和绝缘的分析被调查了。介电常数，反响的频率和 composites 的绝缘的损失在垂直应力和温度下面被测量了，并且在压力和温度下面的材料性质的变化能也被获得。composites 的压力和温度稳定性通过实验被估计了。composites 的这二种类型的数据显示与压力合成的 1-3-2 的稳定性比 1-3 的好合成，并且二 composites 几乎与温度有一样的绝缘的稳定性。然而， 1-3-2 合成显示出的更慢的频率变化比 1-3 合成。

英文摘要：

With the universal test machine and temperature test chamber, the effect of pressure and temperature on the behavior of 1-3 and 1-3-2 piezocomposites prepared with PZT/epoxy in our lab has been investigated through electrical impedance and dielectric analysis. The permittivity, resonant frequency and dielectric loss of the composites have been measured under vertical stress and temperature, and the variety of the material properties under pressure and temperature could also be obtained. The pressure and temperature stability of the composites have been assessed through experiments. The data of these two types of composites indicated that the stability of 1-342 composite with pressure was better than that of 1-3 composite, and two composites have almost the same dielectric stability with temperature. However, 1-3-2 composite showed slower frequency variation than 1-3 composite.
