| 摘 要： | 有限元法已被证明是计算阴极保护场中电位、电流密度分布的有效方法。作者建立了二维的有限元数学模型,并讨论了模型中电化学场的非线性边界条件的处理和非线性方程组的迭代法解法。用构建的模型对简单的阴极保护模拟体系进行了分析,得出了较合理的结果。

| Abstract: | The 2-D finite element method was an effective method to calculate the potential and current density distribution of cathodic protection fields. The author developed a mathematical model of 2-D finite element, especially discussed how to deal with no-linear boundary conditions of electrochemical fields and used iterative method to solve no-linear equation groups. A simple simulated CP example was analyzed through this model and proved that the finite element was a powerful tool. |
