%X 微生物的代谢产物醋酸,对黄铜管的耐蚀性能影响较大.通过对黄铜管在不同醋酸浓度的循环水中的电化学阻抗谱(EIS)的测定和拟合,确定了合适的模型.根据此模型循环,在循环水中加入少量醋酸,可使膜电阻R<sub>1</sub>和电荷转移电阻R<sub>2</sub>的值大大减小,而膜电容C<sub>1</sub>和双电层电容C<sub>2</sub>的值均有增大,这表明黄铜管的耐蚀性能大为降低.;Acetic acid as a metabolite of microbe has a great influence on the corrosion resistance of the brass tube. The electrochemical behavior of the brass tube in recycling water containing acetic acid at different concentrations is studied by electrochemical impedance spectroscopy, and an appropriate model is established through fitting. It is shown that the film resistance R<sub>1</sub> and charge transfer resistance R<sub>2</sub> greatly decrease while the film capacitance C<sub>1</sub> and double-layer capacitance C<sub>2</sub> both increase in the presence of acetic acid. As a result, the corrosion resistance of the brass tube greatly decreases
