If you take a spring, it is true that the period of oscillation is independent of the amplitude but only up to a point.

如果用弹簧，周期的确和，振幅无关，但也只是点到为止。

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.

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。

Due to intense oscillation of these integral, calculation using direct numerical integral, i. e., GPSS (the generalized point source synthesis method), is complex.

由于这类积分的强烈振荡性，直接数值积分，即通常的广义点源叠加方法(GPSS)，计算比较复杂。
