title: [Wavelet transform and its application in spectral analysis].
abstract: Recently, a new mathematical technique known as wavelet transform(WT) has become the focus of many science areas. In analytical chemistry, wavelet transform has been mainly utilized for signal smoothing, de-noising and compression. In this paper, the wavelet transform theory is introduced and its applications in spectral analysis are reviewed.
