摘　　要：本文证明了含ｎ个时间常数的腐蚀电极系统在恒电位阶跃暂态电流过程中任意相邻的ｎ＋１个数据点满足多元线性方程．通过对该方程的多元线性回归分析，可方便地算出暂态过程的电化学参数，判定出未知体系所含时间常数的个数．Abstract It is deduced that any (n+1) consecutive equi-spared data points on a transient curve of a corroding system containing n tine constants under potential step control can be correlated by a multivariate linear equation. Through the multivariate linear regression of the equation, some electrochemical parameters of the transient system can be easily obtained without fitting process, and the number of time constants of the system could be estimated. The validity of the proposed processing is demonstrated for several practical systems.
