研究了不同含硫化合物对铁素体不锈钢和奥氏体不锈钢在０．５ｍｏｌ／ＬＨ２ＳＯ４溶液中阳极溶解行为的影响．结果表明，含有带孤对电子的硫原子的化合物都可以催化不锈钢的阳极溶解．然而不同含硫化合物的催化能力并不相同，对于无机含硫化合物，Ｎａ２Ｓ２Ｏ３，Ｈ２Ｓ，ＫＳＣＮ等的催化能力较强，而Ｎａ２ＳＯ３的催化能力较弱．对于有机含硫化合物，其催化能力随分子体积的增加而降低 The effect of different sulfur compounds on the anodic dissolution behavior of ferritic stainless steel and austenitic stainless steel in 0.5 mol / LH 2 SO 4 solution was studied. The results show that the compounds containing sulfur atoms with lone pairs of electrons catalyze the anodic dissolution of stainless steel. However, the catalytic ability of different sulfur compounds is not the same, for inorganic sulfur compounds, Na2S2O3, H2S, KSCN strong catalytic ability, and Na2SO3 catalytic capacity is weak. For organic sulfur-containing compounds, the catalytic capacity decreases with increasing molecular volume
