摘要： 本文提出一种新的富里叶变换平滑算法并应用于处理阶梯扫描伏安法的实验数据。方法的建立主要是基于平滑原理的缩减步骤、三角函数周期性及和角公式计算正弦、余弦的简化方法。本法对新极谱法实验数据的处理较最小二乘多项式拟合平滑效果更显著。

Abstract: Anew algorithm which performs Fourier transform smoothing has been presented and applied to data of staircase voltammetry. The establishment of this method is mainly based on the cordensation procedure of the smoothing principle,on the periodicity of trigonometric functions and on the simplified method of evaluating sines and cosines with the formula for summation of angles. The practical effect of Fourier transform smoothing Las been compared with that of least-squares-polynomial-fit smoothing.lt maybe seen that Fourier transform smoothing is particularly powerful in the processing of experimental data of neopolarography.
