阶跃伏安法离散数据连续化及导数卷积的方法 Ⅰ.样条插值法

Method of Discrete Data Serialization and Derivative-convolution for Step Voltammetry Ⅰ.Spline Interpolation

本文对采用样条函数插值法解决阶跃伏安法中离散数据连续化及进一步的导数卷积处理进行了详细讨论。用模拟数据和实验数据进行了该方法的效果测试。结果表明,样条函数插值法处理连续化问题,具有显著的优越性,能成功地解决阶跃伏安法在大阶梯增量(△E)快速扫描时存在的由于采样点不多而造成的波形显示、导数卷积后波形杂散等问题。

Spline interpolation.a fine mathematical tool for approximation.was introduced into step voltam-metry in this paper. In this way.it became acceptable that display for the voltamogram with not much data points and derivative-convolution was adopted when the larger step height (ΔE) was used in fast scan. Testing the interpolation effect with theoretical and experimental data.it showed that spline interpolation not only solved the problem in step voltammetry but also expands the application widely.
