摘　　要：声发射技术作为一种无损检测技术,在金属结构的疲劳探伤中得到了广泛的关注和研究。介绍了声发射的基本原理,分析了声发射参数与疲劳力学参数的关系,总结了声发射技术在金属疲劳研究中所取得的成果及在工程中的应用情况,最后展望了声发射技术在金属结构疲劳损伤检测领域的应用前景。The technology of acoustic emission as an effective non-destructive testing method for metal structures has at- tracted wide attention and research. Here, the basic principles of acoustic emission were introduced, the relationship be-tween acoustic emission parameters and mechanical parameters of fatigue were analyzed. The research results and the ap- plication of acoustic emission in the metal fatigue damage were reviewed. At last, prospects of acoustic emission technolo- gy in the field of fatigue damage for metal structure were presented.
