Construction Of NMR Virtual Laboratory Based On Flash Technology

With the development of virtual simulation technology and the rapid popularization of computer network technology, much attention has been paid to the application about virtual instrument, virtual experiment and virtual laboratory in military training, scientific research and teaching, especially the experimental teaching and distance education, industrial design, and related skills training, etc. It becomes a academic research hot spot at home and abroad. With the advantages of the sharing and efficiency, interactivity and autonomy, openness and collaborative, authenticity and immersion, economy and safety, virtual laboratory will have good prospects for development.Analytical instruments has become one of the important application field of virtual experiment technology, however, at present the virtual laboratory about nuclear magnetic resonance spectrum analysis is rarely reported. The literature full compliance with the virtual laboratory of nuclear magnetic resonance spectrum analysis does not been found. Therefore, the development of nuclear magnetic resonance spectrum analysis virtual laboratory has great practical significance and application value. Based on this, this paper used modular ideas for NMR virtual laboratory for the overall design, designed the open spectral library, chose flash as the main design tool, used the object-oriented programming method and advanced application technology such as component combination, then built NMR virtual laboratory with more scenes, highly interactive, easy to maintain and expand. The build mode and technology will also have certain reference significance for other analysis instruments virtual laboratory research.Using the Flash CS3.0animation function and the ActionScript2.0language programming platform, nuclear magnetic resonance spectrum analysis virtual laboratory is constructed. The complete NMR virtual laboratory is constructed by virtual instrument, virtual experiments, spectrogram paint and spectra analysis, simulating the whole experiment. Using the filter technology, true to nature and fake3d virtual laboratory scenes is constructed, achieved strong immersive. Virtual instrument can achieve various functional simulation, the user can undertake all kinds of interactions.The software can automatically and intelligently analysis spectrogram, transform NMR spectrogram into a vector spectrum diagram, accurately provide information about the corresponding functional groups in compounds according to the information of spectra and molecular formula. The molecular structure can be assembled freely by the user. Spectral library is designed to be open type, so it is easy to expand and maintain. Developers and users can add and change the spectrogram according to the demand of themselves. Modular thought facilitate the secondary development of software.The software is small, can be promulgated on network and run stand-alone. It is easy to use and spread.
