| Abstract: | A new pattern recognition technique of fluorescence spectra based on vector distance in n-dimen- sional space was established for the source identification of oil spills on sea. Four wavelengths of both excita- tion and emission were used as digitizing points of fluorescence spectrum. Three unweathered crude oils, four heavy fuels and two lubricating oil. were analyized, and their digitized fluorescence spectra were studied. The reliability of this pattern recognition technique was tested by analiyzing 11 bunker oils collected from different ships, and the smallest vector distance under the experimental conditions was given. |
