时变数据和谱数据测量中干扰数据的剔除与取代

Rejection and Replacement of Disturbed Data in the Measurement of Time Variable Data and Spectral Data

根据时变数据和谱数据的特点，提出了时变数据和谱数据测量中干扰数据合理剔除与取代的几种方法。给出了数据采样频率是物理量变化频率１０倍、８倍和６倍以上时测量精度的适用范围。在大量时变数据和谱数据的处理中应用本文提到的方法对干扰数据进行剔除和取代，均获得了满意的实验结果。

This paper presents several methods of rationally rejecting and replacing the disturbed data when we measure time variable data and spectral data, according to their characteristics. And it gives the suitable limits of measurement precision respectively, when the sampling frequency of data is 10 times.8 times and 6 times of the frequency of physical change. When we deal with lots of time-variable data and spectral data, using the method of this paper to reject and replace disturbed data, the satisfactory experiment results have been achieved. It proves this method is effective.
