The Construction Of The Three-dimensional Web Atomic Absorption Spectrophotometry Virtual Laboratory

Virtual laboratory has attracted great attentions and widely untilized on various arrears because of their important roles in experiment teaching, distance education, vocational training, scientific research, and so forth. With the rapid improvement of computer science and deep investigation of virtual reality technology, people increase their demand of virtual laboratory, such as sharing and efficiency, interaction and independence, openness and coordination, reality and immersion, economy and security, etc. So for, the virtual experiments and instruments hardly satisfy the whole requirements of users from the basic experiment technique to further exploration and research. Therefore, it is significant to construct one kind of virtual instruments and laboratory with three-dimensional scene, real-time interaction, multi-level control and auto-regulative parameters. In addition, integrating different techniques and models during the development and supplying the user comprehensive virtual learning and research experience via network become challenges of virtual laboratory.According to research status of virtual reality technique and virtual laboratory in domestic and abroad, this article deeply discusses technical solutions for building virtual laboratory system, in order to establish realization method and development route of three-dimensional network atomic absorbance spectrometry (AAS) analytical laboratory. Based on Virtools three-dimensional software development platform, this work, using module formula and expansion technique on VSL, constructs three-dimensional network high-interactive AAS virtual laboratory, which contains multi-sample pretreatments, multi-element collections, multi-atomization methods, multi-parameter selections, multi-layer data transfer, instant interaction and information compilation, feedback and evaluation. During the construction, relative factors curves were derived from the actual experiment results and transferred to the virtual laboratory. So that, the users can not only get different experiment data under various conditions by autonomously adjusting the parameters on virtual instruments, but also quickly set up best operation condition under multi-factors through orthogonal test. The users can also obtain spectra data and analysis results under the situation with variable parameter. This virtual laboratory achieves self-simulation with virtue scene and complex analytic process. The described virtual laboratories in this paper possesses the advantages of high simulation, flexible interaction operation, perfect virtual work station, powerful data processing and complete virtual experiments. This work has great potentials to apply on instrument operation training, on-line AAS experiments learning, and so on. Its development model is of reference value to other spectrometry analysis virtual laboratory and analytical instrument virtual laboratory.
