WAVELET ANALYSIS OF EN DATA

摘要

This project has been concerned with an examination of wavelet methods for the identification of corrosion type. A number of authors have examined the use of wavelet methods for the interpretation of EN data, but as yet no clear advantages have been found for this method. This paper reports a new method of presentation of wavelet results that may help to provide better discrimination of the type of corrosion occurring. The discrimination ability of the method appears to be similar to that of the characteristic frequency determined from a shot-noise analysis, but the ability of the wavelet method to discriminate on the basis of frequency may provide benefits in some circumstances.
