摘      要：The thesis has profoundly studied the compression of IR spectra by wavelet transformation. The conclusion indicates: IR spectral characteristics themselves greatly influence the compression ratio(CR). The sampling length of IR spectra made the greatest effect on CR, but the increase of sampling points doesn’t have the same step with that of CR. Under the same reconstructed root-mean-square difference, the probable maximal compression ratio which to be decided by IR spectral complexity of simple spectra is greater than that of complicated ones.
