摘　　要：用失重法及极化曲线方法研究了在CO_2饱和的水溶液中几种硫脲衍生物对碳钢的缓蚀作用.利用缓蚀协同效应得到了在较高温度下缓蚀效果良好的缓蚀剂.Inhibitive effect of some thiourea derivatives on corrosion of carbon steel in CO2-saturated brine is studied by weightloss method and polarization curve measurement. Desired inhibitive efficiency of inhibitor for using at relative high temperature is attained by means of synergistic effect between certain inhibitors.
