| 摘 要： | 通过调整1－3型压电复合材料换能器中压电相的分布，可以控制换能器辐射面上振动幅度和相位的分布，从而获得具有特殊性能的声场．作为辐射源表面振动速度等相位不等幅和等幅不等相位的两种典型情况，本文对边线高斯型换能器和Wesnel聚焦换能器进行了实验研究，讨论了其声场特性．

| Abstract: | Presented is the investigation of 1-3 inhomogeneous piezrycomposite materials which have arbitrary spatial velocity distribution when excites uniformly. As specialcases, we have studied experimentally the sound fields of an edging-Gaussian- distributiontransducer and a nesnel transducer. The method of manufacturing the transducers usinginhomogeneous 1-3 piezo/epoxy composites is discussed. |
