Abstract


As modern society and the rapid economic development, People are moving into a knowledge, information and learning-oriented society.Educational technology and methods put forward higher requirements. However, in addition to revising the theory of teaching. It should also focus on experimental procedures, improving their ability.Virtual laboratory is a virtual simulation of the important applications in the field of education. Virtual experiment is application experiment. It uses computer graphics, virtual model to simulate the actual experiment in order to achieve the purpose of experiment. Chemistry experiment is an important part of high school chemistry teaching.But due to funding, space, equipment and other factors, chemistry experiment failed to achieve the desired results. Experimental teaching quality is concerning.In this paper, it based on a detailed analysis of the theory of virtual experiments, development and related technologies.Using the method of external devices into the virtual model of experimental to improve the work efficiency.Particle system by using to simulate clarifying lime with sodium carbonate precipitation reaction phenomenon.Research focused on this type of chemical dumping of liquid precipitation phenomena simulation experiment.Taking into account the reaction is in the liquid.The movement of liquid impacted precipitation of small particles is also very significant. Based on the famous formula Navier-Stokes Equation,to solve the phenomenon of fluid movement.It is one of the difficulties of the paper.But this study do not care about the accuracy aspects of thermodynamics and the energy . The main algorithm of the model is based on Euler equation of continuity equation and momentum conservation equations.The last experimental development tools in a virtual environment of VC + +6.0 with OpenGL technology to complete a chemical experiment design example of the reaction of clarify lime and sodium carbonate.
