| 摘 要： | 本文从压电学的基本定义出发,推导出两相系0—3型连通性复合压电材料的压电应变常数表达式,进一步修正了T.Furukawa压电应变常数表达式的缺陷,使理论和实验结果更相吻合。利用SEM、X-ray等先进分析手段,探讨了影响0—3型复合压电材料压电特性的机理,得出了影响压电特性的三个主要因素。

| Abstract: | This paper deducts the piezo-constant expression of 0-3 type connectivity according to the basic definition of piezoelectricity, and amends the flaw of T. Furukawa's piezo-constant expression. This makes the theory more correspondent with the experimental results. By means of the analytical methods such as SEM and X-ray, we also discuss the mechanism which affects 0-3 type composite piezoelectricity and get three main factors affecting the piezoelectricity. |
