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。
In this paper, spline function interpolation is applied to solve the discrete data continuity and further derivative convolution in step-voltammetry. The effectiveness of the method was tested by using simulated data and experimental data. The results show that the spline function interpolation method is of great advantage in dealing with the problem of continuation, and it can successfully solve the problem that the step voltammetry is not available due to the small number of sampling points Waveform display, waveform convolution waveform spurs and other issues.
