Study On Infrared Spectrum Virtual Laboratory Basing On The Intelligent Analysis Infrared Spectrum

As a kind of new teching modes of experiment the virtual laboratory is an outcome of the information ages, and it has the vast applied foregroung in the realm of education and research, it is a new development direction of the experiment teaching, therefore, the development of the virtual Laboratory.The IR experiment has many different Preparations, the IR spectrum is sensitive to Experimental conditions, therefore, the construction of virtual IR laboratory is a comparatively complicated process. Based on the technology of Flash 8.0 and ActionScript 2.0 program, The module-design idea, the technology of Flash 8.0+PHP+MY SQL, a Networked and opening virtual laboratories of IR has been constructed. The virtual laboratory makes the study of theory and simulated experiment to become an organic integration, it can automatically recognize and Analysis Infrared Spectra. The module-design idea and opening IR spectrum Datas not only increase networked speed but also maintain and update of the virtual laboratory. A feasible way has been set up for building IR chemical NVL. It is the key point and the difficulty to automatically recognize and Analysis Infrared Spectra, Design for IR spectra datas and simulate infrared imaging's workstation.Infrared spectrometry is a modern instrumental analysis, it has been used for qualitative and quantitative ananlysis of material evidence in judicial identification. Infrared spectrometrycan provide accurate data and analysis conclusion for drug smuggling, explosive detonation, faking cash.Base on the characteristics of material evidence in judicial identification, a IR virtual laboratories for Expert testimony has been constructed. Not only does include drugs and paint being used for infrared spectrum analysis, it also includes inkpad and Roller Pen Inks being used for infrared image analysis. In the NVLs, the whole experiment processes were simulated according to the real instruments operating process. In addition, the NVLs have real scene, simple and convenient operation and can be promulgated on network. The NVLs can good meet demand of experiment education in judicial identification. The NVLs is the beneficial exploration to Theory and Practice of Vocational Education on Criminal Investigation.
