小波函数是具有时域和频域良好局部化特性的函数，理论上可以用于非整次谐波的检测。

The wavelet function is such a function which possesses good localization characteristics, so theoretically it can be applied to the detection of non-integer harmonics.

传统的傅里叶分析由于在时域不能局部化，难以精确检测到信号发生突变的时间。

Conventional Fourier transform can 't localize in time field, so it can' t inspect signal 's break time accurately.

小波变换具有很好的时域和频域局部化特性，它对以非稳态振动为特征的信号提供了很好的分析手段。

Wavelet transformation possesses excellent properties of time-frequency localization and thus provides an effective means for analyzing signals characterized by unstable vibration.
