采用声发射方法监测储运设备及压力容器中304不锈钢的点腐蚀，采集其在质量分数为6%的FeCl₃·6H₂O溶液中的点腐蚀声发射信号，研究声发射信号的规律及特性，总结出点腐蚀信号的特征参量，为工业现场声发射检测的应用提供借鉴。

In industrial production, when the damage and losses caused by corrosion have occurred, it not only reduces the reliability and service life of structures and pressure vessels, also poses a threat to the social economy and people's lives and property safety. Thus, monitoring and forecast related to corrosion should also have received attention. This article will use acoustic emission method to monitor pitting test handling equipment commonly used in industry and pressure vessels of 304 stainless steel. The acoustic emission signals by pitting in 6% FeCl₃·6H₂O solution shall be collected and the change law and characteristics of pitting acoustic emission signal feature parameter shall be summarized up to provide basic data for the industrial field inspection applications.
