本文提出了一个模拟电化学法从混凝土中提取氯化物的数学模型。该模型考虑了离子浓度对带电离子扩散和迁移的影响。推导了外加电场作用下的带电离子在浓溶液中的输运方程。给出了数值计算结果，并与实验结果进行了比较。
This paper presents a mathematical model for simulating electrochemical chloride extraction from concrete. The model considers the effects of ionic concentrations on diffusion and migration of charged ions. The transport equations of charged ions under the influence of an externally applied electrical field in concentrated solutions are derived. Numerical results are shown and they are compared with experiments.
