多个时间常数线性体系暂态响应方程参数的代数求解法
摘要:
从线性条件出发, 推导了含n个时间常数体系恒电位阶跃时暂态响应方程, 并提出一套解析形为ΔI=ΔI_∞+sum from i=1 to n k_iexp(-t/τ_i)暂态方程各未知参数的代数解法。该方法可对未知体系时间常数个数进行判定, 比起一般曲线拟合更加快速简便, 且抗干扰能力较强。

A New Aproach for Processing Data of Transient Response to a Small Amplitude Potential Step
Abstract:
The equation of transient response to a small amplitude perturbation of potential step for multi-time constant electrode processes was deduced, and a method of calculating the parameters in the equation of transient response containing one, two or three time constants was proposed. Using this method, the number of time constants can be determened unambigiously, and the kinetic parameters of the electrode process studied can be estimated easily.
