由栾桂冬、张金铎、王仁乾编著,北京大学出版社出版的《压电换能器和换能器阵》一书,即将与读者见面。 北京大学声学专业多年来一直为高年级和研究生开设换能器和换能器阵课程。在这门课长期教学基础上,广泛征求读者意见,经多次修改,并补充近年来换能器和换能器阵研究方面的成果和分析方法编成这本书。 全书四十多万字分上下两册,共十五章。上册包括第一章至第九章,下册包括第十章至第十五章。第一章简述了压电换能器和换能器阵的发展及这门学科对声学的发展、研究和应用的重要性。第二章系统讲述了晶体的宏观对称性,晶体的弹性、介电性和压电 Written by Luan Guidong, Zhang Jin Duo, edited by Wang Ren, Peking University Press published “piezoelectric transducer and transducer array,” a book, is about to meet with the reader. Acoustics at Peking University has been offering transducers and transducer arrays for senior and graduate students for many years. Based on the long-term teaching in this course, we solicit the opinions of readers extensively and make several amendments to it. We have supplemented the achievements and analytical methods of transducer and transducer array research in recent years into this book. The book more than four hundred thousand points in two volumes, a total of fifteen chapters. The first volume includes the first chapter to the ninth chapter, the second edition includes the tenth chapter to the fifteenth chapter. The first chapter outlines the development of piezoelectric transducers and transducer arrays and the importance of this discipline to the development, research and application of acoustics. The second chapter systematically describes the macroscopic symmetry of crystals, the elasticity of crystals, the dielectric properties and the piezoelectricity
