中文摘要：

沿海、盐碱地电厂等混凝土建、构筑物受盐害作用，导致其使用寿命降低。故建立二维模型，以理想溶液中离子的质量守恒方程、Nemst-Plank方程、电流平衡方程、电中性方程这4个方程为理论基础，结合溶液和试块中离子初始含量以及溶液一试块交界处的边界条件，求解偏微分方程得出三乙烯四胺阻锈剂双向电渗技术处理后溶液、试块中离子浓度等理论解，然后和试验数据进行对比。结果表明，在趋势上，理论解较好的拟合了试验结果，采用合适的理论分析模型可以很好的指导双向电渗技术在实际工程中的应用。

英文摘要：

In coastal and saline alkali area,power plants and other concrete structures are subjected to salinization, resulting in decrease of service life.Therefore, it intends to establish two-dimensional model, which bases on the four equations of the mass conservation equation,Nernst-Plank equation,the current balance equation and neutral equation of the ions in the ideal solution.And combine with the initial ion content in the solution and the block, as well as the boundary condition at the junction of solution and block.To solve partial differential equations and get the theory solution of ion concentration in solution and block after bilateral electro-osmotic method with triethylenetetramine inhibitor.Then they are compared with the experimental data.Results show that the trend of the theoretical solution better fitting the experimental results, the appropriate theoretical analysis model can be a very good guidance for electro-osmotic method in practical engineering application.
