中文摘要:

      针对压力容器的微裂纹缺陷，以S25H-20型有机热载体锅炉为被测对象开发了声发射缺陷监测系统，该系统采用LabVIEW软件设计人机界面，包含了声发射信号采集、存储与回放，提取关键参数等功能，并通过接口功能结合Matlab强大的信号处理能力进行混合编程，实现对圆柱体压力容器的底面缺陷的快速准确定位。

英文摘要:

      An acoustic emission (AE) monitoring system has been developed for micro-crack monitoring of pressure vessel，and used on S25H-20 organic heat carrier boiler.In this system，human-machine interface (HMI) designed by LabVIEW，with functions of signal acquisition，storage and replay，and key-parameter extraction is adopted.With the powerful signal processing capability of Matlab，the defects on cylindrical pressure vessel bottom surface can be rapidly and accurately located.
