The Development And Application Of Physics Experiment Data Processing System

In physics experiment course, The students should comply with the compliance of the experiment, and process the experiment data in accordance with the requirements of experiments, which is a quite important step during the whole experiment process.The physics experiment need to measure a huge universe of initial data.The math formulas are miscellaneous. Human data-processing work is very cumbersome and prone to error. To avoid complicated manual calculation and mapping for increase the accuracy of data processing and improve the learning efficiency, using computer for powerful data processing and graphics, the experimental physics data processing system is necessary to set.Physics experiment data processing system is to achieve manual data input in the first part, to exclude the highly unusual data, according to the law of propagation's uncertainty to calculate, to achieve data processing by the error theory, according to demand to do the relevant curve drawing, and the results of the experiment can be automatically evaluated. Using the second part of the physics experiment data processing system, the sensor and data acquisition can read the data in real time and processing data can be synchronized with the drawing of experimental curve. All experimental data can be safely queried by physics teachers. Thus to improve student's interesting in physics experiment course, to improve overall physics experiment teaching level.In this paper, the physics experiment data processing system are developed using the object programming languages Visual C++6.0, the technology of hybrid programming between VC+ and Matlab, according to the individual characteritics of VC++ and matlab and the technology of ADO access the ACCESS database.Physics experiment data processing system is now in trial operation stage.Students can accurately and rapidly process the experimental data by using this system, thereby increasing student's interesting and experimental capabilities in physics experiments, reinforcing student's understanding in physics experiment.At the same time, teachers can inquire student's experimental results from physics experiment, get communication with students, continue to improve teaching, and heighten the standard of teaching physics experiments.
