本文描述了与开发金属释放和腐蚀在线监测新方法相关的实验结果和理论建模。这是通过测量停滞和流动期间的腐蚀电位（Ecorr）变化（CPSF方法）来实现的。在没有游离氯的情况下，Ecorr值与铜的浓度密切相关。在有氯存在的情况下，Ecorr的行为还有一个额外的特点:在停滞期开始后，腐蚀电位迅速降低，并达到最小值。基于数值模拟对这种生态抑制行为进行了检验。据确定，Ecorr瞬态的强度对氯的存在很敏感，并随其浓度线性增加。 得出的结论是，对于探索了CPSF电池中不含氯的Ecorr行为的系统，其在含氯情况下的量化可用于确定游离氯衰减速率和由氧还原定义的腐蚀电流。包括7个参考文献、表格、图表。

This paper describes results of experiments and theoretical modeling relevant to the development of a new approach to on-line monitoring of metal release and corrosion. This is done by means of measurements of changes of the corrosion potential (Ecorr) during stagnation and flow (CPSF approach). In the absence of free chlorine, the values of Ecorr are strongly correlated with the concentration of copper. In the presence of chlorine, the behavior of Ecorr has an additional feature: immediately following the start of a stagnation episode, the corrosion potential rapidly decreases and reaches a minimum. This type of Ecorr behavior was examined based on numerical modeling. It was determined that the intensity of the Ecorr transients is sensitive to the presence of chlorine and increases linearly with its concentration. It was concluded that for systems for which the behavior of Ecorr without chlorine in CPSF cells has been explored, its quantification in the presence of chlorine can be utilized to determine the rate of free chlorine decay and the corrosion current defined by the reduction of oxygen. Includes 7 references, tables, figures.
