AbstractNOVELTY - The method involves collecting overflow crude oil and Raman fingerprint data. A horizontal coordinate is measured by a Raman spectrograph. A visible light laser is formed as an excitation light source. The Raman fingerprint data is obtained for realizing cluster analysis. A crude oil spill areas clustering result is obtained. A vector is formed in a multi-dimensional space by installing SPSS software. A coefficient of a vector included angle is obtained. USE - Micro-con-focal Raman spectroscopy based short-term weathered oil tracing method. ADVANTAGE - The method enables avoiding uncertain Raman data processing software deducting baseline forming factors and processing error generating phenomenon, improving short-term weathered oil tracing reliability and realizing responsibility affirming and economic compensation operation of oil spilling event. The method enables effectively realizing pollution controlling and polynomial environmental restoration operations. DESCRIPTION Of DRAWING(S) - The drawing shows a graph illustrating relationship between micro-con-focal Raman spectroscopy based short-term weathered oil tracing characteristics.'(Drawing includes non-English language text)'
