综述了近几十年来国内外大气腐蚀研究方法的发展，重点介绍了大气腐蚀的加速试验方法、电化学研究方法和实时监测技术。湿热试验、盐雾试验、周期喷雾复合腐蚀试验、干湿周浸循环试验和多因子复合加速腐蚀试验是目前使用较多的加速试验，而多因子复合加速试验是模拟大气腐蚀加速试验方法以后发燕尾服的方向；发展了研究薄液膜的电化学测试技术，大气腐蚀监测电池ACM和Kelvin探头参比电极技术，极化和阻抗测量方法通常用于干湿交替加速试验中，也用于测试带锈试样在浸渍液中的电化学行为；原位动态实时监测技术的发展促进了从微观水平对材料大气腐蚀机理的研究工作的开展，最后提出了今后大气腐蚀研究方法的发展趋势。

The present status and development of research methods on atmospheric corrosion were comprehensively reviewed. Acclelerated laboratory test, electrochemical measurements and in-situ monitor tecnology were emphatically introduced. Wet and hot test, salt spray test, periodic spray complex test, wet and dry intermittent immersion cyclic test, multi-factor complex accelerated corrosion test. While multi-factor complex accelerated corrosion test is the development trend in the future;electrochemical measurement technology for studying the corrosion mechamism in the thin layer electrolyte was generated:atmospheric corrosion monitor and kelvin probe vibrating capacitor technique, polarization and impedance measurement methods was usually used to cyclic wet and dry accelerated test and also used to test electrochemical behavior of sample wit rust in the immersion solution;the application of in-situ monitor technology contributed to launch the research on the mechanism of atmospheric corrosion from microcosmic aspect. In the end, this article puts forward the development trend of the future of atmospheric corrosion research methods.
