摘　　要：用失重法研究了撑绿杂交竹竹叶固体提取物在1.0mol/LHCl溶液中对冷轧钢的缓蚀作用。结果表明:撑绿杂交竹竹叶提取物对冷轧钢在1.0mol/LHCl中具有良好的缓蚀作用,且在钢表面的吸附符合Langmuir吸附等温式,并详细讨论了缓蚀剂浓度、腐蚀时间、温度对缓蚀作用的影响规律。The inhibition effect of the solid extractive from Bambusa pervariabilis × Dendrocalamopsis oldhami leaves on the corrosion of cold rolled steel （CRS） in 1.0 - 7.0 mol/L HCl has been studied by weight loss method. The results show that the extractive acts for CRS, and the adsorption on the CRS surface follows the as a good inhibitor in Langmuir adsorption 1.0 mol/L HC1 isotherm equation. Effect of inhibitor concentration, temperature, acid concentration and immersion time was also studied and discussed in detail.
