Research On The Domain Model Expression Method In Physical Simulation Experiment

With the fast development of national education information, the education resources construction becomes a focus of the Information technology education application. Whether for the creation of the digital environment to provide resources services, or to explore collaborative learning autonomy, learning resources always be the center to start.The design and development of the three-dimensional imaging system play an important role in educational resources.The secondary school physics experiment is the content of physical simulation experiment,and the virtual reality technology is the mean of it. It constructs a set of modelling's tool which serve the teachers in class as well as the students after class. The simulation experiment not only assist teacher for teaching and help the student to study independently, and it reduced the experimental cost, also has overcome the difficult position which the condition limited and the high danger is unable to demonstrate.Three-dimensional imaging system with a lively, visual image, interactive characteristics, and they can independently explore .The conventional teaching methods could not deal with the problem . At present, both at home and abroad the three-dimensional technology, virtual reality technology applied to the teaching still relatively be little, to the field of three-dimensional imaging system model method of expression even less.This paper research the the domain model expressed method in physics simulations experiment.It poposes one kind of thought which based on the decomposition and the combination and the discipline domain model structure characteristic hierarchical structure domain model expression method, its goal lies in the physical question solution and the physical experiment simulation question expression unifies in the same domain model. The research indicated that this kind of expression system is feasible, it has direct-viewing, clear and the natural merit.
