| Abstract: | This paper describes the experimental method and principle to measure the Planck constant with the curvature method.First,the curve is simulated both automatically and accurately by using Origin7.5.Then a mathematical formula of cut-off voltage is derived with the aid of higher mathematics.And finally the C language editing procedure is applied for automatic processing of the experimental data.This paper proves the feasibility of the experiment for measuring the Planck constant with the curvature method,providing researchers with a method which not only makes the data processing faster and more accurate but also improves the efficiency of the experiment. |
