Making of the Intelligent Data Processing System for the Experiment in the Determination of the Thermal Coefficient

Abstract

For the problem that the intelligent physics experimental data processing system based on Multimedia ToolBook is only suit for 32 bit computer, the new developing intelligent experimental data processing system based on Flash is put forward. The intelligent experimental data processing system is used to quickly checking the results of the student Physics Experiment report. The results of the Physics Experiment report are descripted on the average and the uncertainty which the reliability is 99.7%. The uncertainty is kept one digit and it is aligned with the last digit of the significant figure. The uncertainty carried and the significant figure rounded. The intelligent experimental data processing system of the Thermal Coefficient Determination is an example. There are two aspects based on Flash. The first one is the interface design. Another is program design. In the program design the intelligent look-up table from the temperature difference electromotive force to temperature is designed with the principle that if it is the same the temperature is given directly and it is not the same the temperature is obtained with linear interpolation. The coordination transformation is used to show the experimental data points. The Least Square Method is used to fitting curve of the temperature and the cooling time with logarithm operation. The successful development of the intelligent data processing system of the Thermal Coefficient Determination is good for development of other experimental data processing system.
