对一放置2年时间的储罐试验模型进行长周期的声发射腐蚀监测，通过研究其在稳定腐蚀状态下的声发射信号特征，分析其腐蚀的机理和信号产生的原因，形成对储罐腐蚀更深入的认识。文章还对稳定腐蚀状态下的储罐声发射特征参数进行统计分析，为后续的储罐在线声发射检测评价打下数据基础。%AE (Acoustic Emission) monitoring of a storage tank model placed for 2 years is carried out. By studying the AE signal feature in stable corrosion condition, analyzing the mechanism of corrosion and the cause of AE signal, a more in-depth understanding of storage tank corrosion is formed. Statistics on AE feature parameters of stable corrosion is also performed, laying data foundation for subsequent AE online detection and tank evaluation.
