摘　　要：利用电化学方法测定了缓蚀剂烯丙基硫脲在不同温度和不同浓度下的缓蚀性 ,初步探索了缓蚀剂烯丙基硫脲的吸附机理 .并比较了不同条件下缓蚀剂烯丙基硫脲和苯基硫脲缓蚀作用的差异 .初步分析了缓蚀剂分子的结构对缓蚀性的影响 .The inhibitory action of Allyl thiourea at different temperature in sulphuric acid media has been studied by using electrochemical methods. And the mechanism are briefly discussed. The different inhibitory action of Allyl thiourea and Phenyl thiourea have been compared with. And from their structure and inhibitory effect, the influences of some organic structure and functional groups have been briefly analyzed.
