用压力脉冲法研究了在钙掺杂ＰＴ（钛酸铅）陶瓷粉末与Ｐ（ＶＤＦ－ＴｒＦＥ）（偏氟－三氟乙烯共聚物）复合材料中ＰＴ粉末与聚合物基体对于总的压电效应的贡献。实验结果表明，在此类复合型压电材料中，聚合物基体对于整体压电性的作用是不可忽视的，而且，陶瓷粉末与聚合物基体对于整体压电性的贡献恰好是相互抵消的。
The effect of PT powder and polymer matrix on the total piezoelectric effect in Ca-doped PT (lead titanate) ceramic powders and P (VDF-TrFE) (PVDF) composites was investigated by pressure pulse method Contributions. Experimental results show that in such composite piezoelectric materials, the effect of the polymer matrix on the overall piezoelectricity can not be neglected. Moreover, the contribution of the ceramic powder and the polymer matrix to the overall piezoelectricity exactly cancel each other out.
