中文摘要:
      介绍一种采用压电加速度计作敏感元件的球形声压梯度水听器.从理论上分析了球体直径及重量对水听器灵敏度频率响应和指向性的影响;描述了该水听器的设计细节;给出了作者所研制水听器的性能测试结果.
英文摘要:
      This paper reports on a kind of pressure gradient hydrophone with co-osillating sphere in which piezoelectric accelerators are used as sensing elements. Influence of diameter and weight of the sphere on the sensitivity freqency reponse and the directivity of hydrophone are analyzed theoretically, detalls of design of the hydrophone are described and experimentally measured sensitivity and directivity characteristics are given.
