通过分析气柜防护层失效原因，建议对该类气柜的防护应采用涂料、阴极保护和缓蚀剂联合保护措施。
The combination protection measures of application of corrosion-resistant coatings, provision of cathodic protection, and addition of corrosion inhibitor are suggested to prevent corrosion.
该类缓蚀剂对阳极反应和阴极反应均有抑制作用，属于混合型缓蚀剂。
They can inhibit reaction of cathode and anode, and thus be regarded as a mixed corrosion inhibitor.
实验表明，该缓蚀剂可与碳钢表面螯合形成致密的覆盖膜，表现出明显的阴极型缓蚀剂特征。
The results showed that, with the inhibitor YWY, a compact overlayer film was obtained on the metal surface and YWY showed cathode corrosion inhibitor.
