摘　　要：在测定普朗克常量实验中,利用光电效应法测出不同频率的入射光对应的截止电压,然后运用Mathstudio对实验数据进行拟合,并与最小二乘法、MATLAB、Origin和Excel的处理结果进行对比。结果表明:Mathstudio具有其他方法相同的准确性和精度,并且更具便携性和可操作性。Mathstudio的运用能够促使学生不断探索新知识,进一步培养学生的创新精神,同时推动实验教学方法的改革,完善教学效果。The cut-off voltages corresponding to incident light with different frequencies were measured through photoelectric effect method in the experiment of measuring Planck’s constant. Mathstudio was used to fit the experimental data and the processing results of least square method,MATLAB,Origin and Excel were compared.The results show that Mathstudio has the same accuracy and precision as other methods and is more portable and operable. The application of Mathstudio can help students to continuously explore new knowledge and further cultivate students’ creative spirit. Meanwhile,it can promote reform of experimental teaching method,and then perfect teaching effect.
