摘要：The Planck constant is an important constant in modern physics. Its experimental verification is generally by the experiment of photoelectric effect. The data processing is very complex. In order to simplify the complex question the intelligent system “Measuring of the Planck constant with photoelectric effect” had been developed with multimedia authoring tool Multimedia ToolBook. The experimental data was of large number that obtained by user after the leakage current between electrodes and the anode current had been compensated. When the data had been filled the corresponding fields, the intelligent system could display dynamically the volt-ampere curve and the speed displayed could be adjusted. Especially when the user only completed the 3 or 4 filters experiments and the number of the clamp voltages was 3 or 4, the intelligent experimental data processing system could display the slope of the fitting straight line and the Planck constant. In laboratory it provided five filters. The intelligent system used the technologies such as the statistics method of “Non zero plus one”, “the least square method”, “rounding off”, “The uncertainty had a bit and it was aligned as the last bit of the significant figure”. After the arbitrarily 3 or 4 values of the clamp voltageor all 5 values of the clamp voltage had been filled in the fields, the slope of the fitting straight line could be calculated and be drawn, and the Planck constant and its uncertainty could becalculated and be displayed. The fitting straight line was the relationship between the clamp voltages and the incident light frequencies. The Planck constant was obtained by multiplying theslope of the fitting straight line with the electronic charge. These methods could be applied to develop various intelligent experimental data processing systems
