应用浸渍－润湿－干燥循环法研究了氯化物、硫污染物对碳钢大气腐蚀的影响。用△Ｗ＝Ｋ·ｔｎ对数据进行了回归处理。结果表明：在腐蚀初期Ｃｌ－与ＨＳＯ＿３￣－存在协同作用，但随着腐蚀的进行，这种作用减弱。文中对协同机理进行了探讨。
The effects of chloride and sulfur on the atmospheric corrosion of carbon steel were studied by impregnation-wetting-drying cycle method. The data is regressed using ΔW = K · tn. The results show that there is a synergistic effect between Cl- and HSO3- during the early stage of corrosion, but this effect is weakened with the progress of corrosion. The paper discusses the cooperation mechanism.
