【摘要】 研究腐蚀电场平面问题的边界元理论和分析方法。首先,详细论述腐蚀电场平面问题的边界元理论。其次,针对电极极化曲线的非线性特性,提出一个求解含非线性边界条件的边界元问题的迭代解法。最后,按本文所述理论和方法,具体计算了某些电偶腐蚀电场的电位与电流密度分布,并与有关实驻结果比较,发现二者相符甚好。更多还原

【Abstract】 This paper concerns with the applications of the boundary element method to electric field problem associated with corrosion.To treat the nonlinear boundary conditions introduced by nonlinear polarization characteristics, an iterative technique is proposed. This analysis is applied to a galvanic corrosion couple and compared with the experimental results. Procedures presented in this paper have been shown to be accurate, convergent and efficient.更多还原
