压电与压磁声电转换材料的研究及应用

Research and Applications of Piezoelectric and Piezomagnetic Acoustoelectric Transducer Materials

对应用于声电转换方面的两类材料──压电与压磁声电转换材料的制备作了研究，对它们的压电效应与压磁效应、电致伸缩与磁致伸缩及其应用作了归类比较。并且指出，在有些重要应用方面它们将长期共存及相互不可替代。

In this paper,the preparations of piezoelectric and piezomagnetic materials for a-coustoelectric transducers are studied,And,their piezoelectric and piezomagnetic effects,elec-trostriction and magnetostriction as well as their applications are classified and compared. It is-pointed out that these two kinds of acoustoelectric materials can’t replace each other in some im-portant applications and will be longterm coexistence。
