| 为了解介质中的LAPLACE方程,根据有限元法能够预测复杂体系中阴极保护电化学场的分布原理。使用8节点立方体和合适的形状函数对构筑物表层和周围场域进行了离散。通过对各单元的分析和整个求解区域的综合,建立了三维的有限元数学模型,根据此模型编写了相应的C语言程序。通过对模型的计算得出了电位电流密度分布图,发现规律与经典电场原理相符合。 |

| Abstract: |
| Finite element technique was applied to predict the distribution of CP electrochemical field in a complicated system. To solve LAPLACE equation, 8-nod cubic unit and appropriate function were applied to discrete the structure surface and its environment. After analysing each unit and the whole area, a 3-D finite element nodel and a corresponding c language program were constructed. The potential and iso-current density distributions were obtained. The results agreed with classical electric principles. |
