It influences the miaow thiazole quinoline to lose slowly that the experiment is drawn the pharmaceutical loses slowly the factor of performance has temperature mainly, density, the membrane time in advance, and design many group's simulation systems for different influence of these three factors, is it is it should lose pharmaceutical to lose pharmaceutical slowly one positive pole type , lose performance is it is it form space location hinder after the membrane to absorb to come from mainly slowly slowly to appear to prove, thus isolated the carbon steel base body and corrode the medium.

实验得出影响咪唑啉缓蚀剂缓蚀性能的因素主要有温度，浓度，预膜时间，并针对这三个因素的不同影响设计了多组模拟体系，验证出该缓蚀剂是一种阳极型的缓蚀剂，缓蚀性能主要来自于吸附成膜后形成空间位阻，从而隔离了碳钢基体和腐蚀介质。

The resul ts indicated:(1) When micrococcus existed,carbon steel corrosion was accelerated by a loose and heterogeneous biofilm formed on its surfaces;(2)Rpo an d Cc values were close after two days and four days immersion respectively in solutions with micrococcus,which indicated that the metabolization of bacteria became sta ble,and the biofilms under two conditions were tend to be ripe and accordant;(3) The equivalent circuits for situations without or with bacteria were proposed respectively,and the parameters in circuits were also calculated;and (4) Corrosi on reaction impedance with micrococcus showed dispersion effect.

结果表明：（1）小球菌存在时试样表面上所形成的疏松、不均匀的生物膜加速了碳钢的腐蚀过程；（2）有菌存在时暴露2 d、4 d的Rpo值和C c值较为接近，表明细菌的生长代谢过程渐趋于稳定，两种暴露条件下所形成的生物膜趋向于成熟一致；（3）分别提出了有菌和无菌条件下EIS的等效电路，并计算了相应的等效元件参数；（4）小球菌影响下腐蚀反应的阻抗行为存在弥散效应。
