| Abstract: | The trace paint evidences in traffic accidents are identified by IR microscope and scanning electron eicroscope/energy dispersive X-ray spectrometer(SEM/EDS).The infrared spectrum characteristic peaks of all kinds of vehicle paints in markets were analyzed,and the practical identification method of the trace paint evidences in traffic accidents was studied.The method is convenient and fast with the characteristic of nondestructive analysis,and the sample can be analyzed without pretreatment and the amount of sample needs a little.The method can meet the need of the trace paint evidences in traffic accidents rapid identification,and the experiment result can provide a scientific basis for case. |
