摘要：
The technique of wavelet analysis is discussed in the context of line-profile variations in rapidly rotating stars undergoing non-radial pulsation. This technique may be used to determine the harmonic degree l of the pulsation using isolated residual spectra; it is able to handle spectra with relatively low signal-to-noise ratio levels, and is well suited to extracting previously unobtainable information from low-quality, patchy data. A demonstration of the technique is presented using data generated from a spectral synthesis code.
