摘　　要：本论文所阐述的水听式传感器基于一种新概念而开发,以影响塑料管道漏水探测效果的核心因素为设计框架,通过判定和分析来自塑料管道漏水声的频率,从而提高相关仪的非金属管漏水检测能力。本文中所论述的新型水听器具有独特的结构,并在塑料管道漏水探测方面得到了现场印证。The hydrophone in this study was developed based on a new concept by id entifying problems affecting efforts to detect water leakage from plastic pipelines and finding frequencies of leakage sound propagating through plastic pipelines,to improve the ability to detect water leakage from the same,which had proved relatively difficult.The hydrophone developed this time is uniquely structured and assessment of its performance revealed an ability to detect water leakage which conventional piezoelectric sensor could not detect.The results obtained are summarized below.
