摘要
对涂装金属体系通入恒定电流进行极化,测量的充电曲线数据可以用多种方法进行解析.提出使用数值微分方法求出充电曲线的一阶和二阶导数,将充电微分方程式转变为线性方程,从而很容易求出涂装体系的等效电路参数.
After galvanostatic charge curve data of a painted metal system were obtained. The first and second time differentials of charge curve at every sampling point were calculated with numerical differentiation and the charging differential equation was transformed to a set of linear equations with three unknown coefficients, which could be solved easily. The electrochemical parameters in equivalent circuit of the system could be obtained from these coefficients of linear equation.
