讨论了串联２－２型压电复合材料的介电损耗ｔａｎ δ、介电击穿Ｅｂ等介电特性。通过测试复合材料的谐振频率ｆｒ和反谐振频率ｆａ，计算出了２－２型复合材料的压电常数ｄ３１、ｄｈ，ｇｈ以及优值ａｄｈｇｈ并讨论了它们的变化规律。文章对压电常数作了数学模拟，实验结果表明：在压电陶瓷（ＰＺＴ）体积含量较高时，实验值与计算值比较吻合。
The dielectric loss tan δ, dielectric breakdown Eb and other dielectric properties of series 2-2 piezoelectric composites are discussed. The piezoelectric constants d31, dh, gh and the excellent value adhgh of 2-2 composites were calculated by testing the resonant frequency fr and the antiresonance frequency fa of the composites, and the variation rules of them were discussed. The article made a mathematical simulation of the piezoelectric constant. The experimental results show that the experimental value is in good agreement with the calculated value when the content of piezoelectric ceramic (PZT) is high.
