| 摘 要： | 利用单纯形推移法，对三参数和四参数极化方程式求取电化学动力学参数拟合，然后将拟合结果作为高斯－牛顿法的初值，解决了后者初值选择限制问题。将其应用于实测数据与模拟数据的拟合，取得比较好的效果。

| Abstract: | The simplex method is firstly applied to fit the data which derive from the three-and four-parameter weak polarization curve equation of electrochemical dynamics in the corrosion process. Then the above results are used as initial value of Gauss-New ton to calculate parameters. This simpiex Gauss-New ton method breaks the initial value limit of Gauss-New ton and obtains better fitness between calculations and measurements of parameters. |
