Analysis On The Test Of Micro - Material Evidence Of Traffic Accident

Traffic accident material evidence of trace material evidence identification technology is to use modern scientific knowledge and inspection technology, discovery, collection, inspection and material evidence identification of traffic accident, and the inspection and appraisal principle, method and technology, to provide evidence for the traffic accident of a technology science. At the same time, it is also a traffic accident treatment, kinematics, mechanics, forensic science and analysis chemistry, the formation of a multidisciplinary edge discipline. It depends on the development of natural science and social science, more dependent on the modernization of the development of new technologies. Traffic accidents more for the exchange of collision and friction force, the material exchange theory is that every contact must be left in each other. When the material is relatively little, you need to trace material evidence identification technology in traffic accident identification, and trace material evidence in the traffic accident and has its own characteristics, thus appraisal is difficult. Trace material evidence identification technology at present, the traffic accident at the start-up stage, some basic principles and basic laws still need systematic and in-depth research. Starting in the 90 s, the analytical method of trace material evidence gradually to the diversity, scientific direction. Have infrared spectrometry, atomic absorption spectroscopy, Raman spectroscopy, thermal analyzer and other technology applied to trace material evidence identification, greatly improved the role of trace material evidence identification in traffic accidents. But the steps of the progress of science and technology has never stopped, analysis of the new technology of the 21 st century have? Can be used to trace material evidence of identification? Apply to the identification of what are the advantages? Are we need to solve the problem. Trace material evidence is a based on the analysis of the instrument discipline, to make its development, will be constantly updated detection method, discover new testing instrument, detection more accurate.
