摘　　要：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 recognition and correction method for false point by using first order differential is introduced. It is stated that under heavy shock disturbance after processing with the first order differential the influence of random interference can be eliminated by average method for smoothing.
