摘　　要：应用动电位扫描技术研究了油溶性咪唑啉酰胺缓蚀剂对碳钢在弱酸性H2S／HCl复合酸溶液中的缓蚀行为，并采用三参数拟合方法对极化曲线进行拟合计算，算出相应的βA，βk。Icorr等值。Inhitition behavior of two imidazolines WS-l andHT01 was studied in acidulous H2S solution by dynamic potential scanning method controlled by computer,then three parameters evaluation process was adoptedin cathodic-anodic polarization carve analysis, so electrochemical parameters βA,βk, Icorr were gained selatively. The results showed that the inhibition of HT01 was better than that of WS-l. Farther calculation enunciated the absorption of WS-1 on carbon steel surface obeyed Langmuir rsotherm equation much better than HT01.
