摘要
本文用菲涅尔积分推导了非稳态条件下的第一周期示波计时电位方程,用球形扩散的边界条件和Fick第二定律,推导了球形电极示波计时电位理论方程,获得了一些有用的结论。
Equations for the first cycle and spherical-controlled diffusion of oscillographic chronopotentiometry were derived in this paper. Incision of dE/dt-E curve under the condition of the first cycle is more censitive than that under the steady process. Upon the polarization of alternating current with high sweep, the diffusion-layer on the electrode surface becomes as thin as a wafer, so the equation of spherical-controlled diffusion is equal to that of plane-controlled diffusion.
