其次用一种新方法建立了一个区间，以至于矩阵的所有奇异值包含在每一个区间内，并且这个区间是一个递减序列。
Secondly, construct an interval in such a way that all the singular values are contained in each interval, and this interval is a decreasing sequence.
传统的模极大值序列处理方法虽然可以保留信号特征，但降噪后的信号在奇异点有毛刺和轻微的振荡。
Although traditional processing method of modulus maximum array can retain characteristics of signal, the signal after de-noising exists thorns and slight oscillation at singularity point.
