摘　　要：通过室内试验证明硫酸盐还原菌 (SRB)对钢铁腐蚀有较大的影响 ,并且与温度及二价铁离子浓度有关。对于Q2 35A钢而言 ,温度为 2 5～ 37℃时 ,SRB的存在会促进腐蚀 ,且随Fe2 + 浓度的增大腐蚀作用增强 ;温度为 6 0℃时SRB能抑制腐蚀。对J- 5 5钢而言 :温度为 37℃时 ,SRB促进腐蚀 ,且随Fe2 + 浓度增大腐蚀作用增强 ,温度为 6 0℃时 。The laboratory tests indicated that the sulfate reducing bacteria (SRB) had a greater impact on the iron and steel corrosion, which were also related to the temperature and the concentration of diadic iron ions. For Q235A steel, SRB could promote the corrosion when the temperature was 25～37℃ and the corrosion increased with increasing Fe 2+ concentration, whereas SRB could inhibit the corrosion at a temperature of 60℃. For J-55 steel, SRB could promote the corrosion when the temperature was 37℃ and the corrosion increased with increasing Fe 2+ concentration, whereas SRB could inhibit the corrosion at a temperature of 60℃.
