介绍了利用一阶差分对原始数据的虚假点进行识别与纠正的方法,提出在严重冲击干扰时,在一阶差分处理之后,可再采用平均法进行平滑处理,以削弱随机干扰的影响.
The method of identifying and correcting the false data of the original data by first-order difference is introduced. It is proposed that after the first-order differential processing, the average method can be used again to smooth the impact of severe impact interference to reduce the influence of random interference.
