研究了二胺和三胺对铜在酸性介质中的缓蚀作用效率，结果表明，二胺的缓蚀作用效率比三胺的作用效率要大。实验所采用的方法为电化学方法和重量法。酸性介质中铜腐蚀的阻抑
The effects of diamine and triamine on corrosion inhibition of copper in acid medium were studied. The results showed that the corrosion inhibition efficiency of diamine was higher than that of triamine. The method used in the experiment was electrochemical method and gravimetric method. Inhibition of copper corrosion in acidic media
