Abstract: An introduction of wavelet transform and multiresolution analysis is presented.The IRspectra of polyethylene are compressed and reconstructed successfully by Daubechies'compactly supported orthogonal wavelet bases and Mallat's algorithm.The IRspectra can be reconstructed satisfactorily even though the original data are compressed 5 times,and the mean variance is 0.260.This makes the storage,index and processing of IRspectra more conveninet.

Key words: Wavelet transform, Multiresolution analysis, IR spectra, Data compression
