摘要
在以往几年内,已经研制出了一些具有大的各向异性压电特性的改性PbTiO_8陶瓷。它们在水声和超声技术的应用上是一些很有前途的材料。本文简要地叙述了PbTiO_8陶瓷的改性,着重介绍了这些改性后的材料在水声和超声换能器上的应用。
In the past few years, tnodified PbTiO3 ceramics have been developed which possess extremly anisotropic piezoelectric proderties. They are the promising materials for applications in underwater acoustics as well as ultrasonic technology. This paper briefly presents the modification of PbTiQ3 ceramic with emphasis on applications of modified materials in underwater acoustic and ultrasonic transducers.
