| Abstract: | The data-processing system for Photoelectric Effect experiment is designed based on LabVIEW. Multi panel control function is realized by technology of VI server. The problem of the quantity of data is limited which is solved by array control. The function of curve fiting, displaying curve graph, calculating the Planck constant and the relative error are realized by the system. The problem of the complex calculation of data processing is solved. And the efficiency of the experiment is improved. |
