摘　　要：建立了三棱镜光路图的数学模型,应用MATLAB绘制光路图,检验了模型的正确性.随着三棱镜的旋转,直观地演示了分光计中光路图和偏向角的变化过程,指出了最小偏向角.After establishing mathematical model,the light-path map in refraction index measurement of three prism with spectrometer was drawed by MATLAB,and the correctness of mathematical model was verified.The change process of light-path map and deviation angle in spectrometer was demonstrated intuitively by rotating a triangular prism.Furthermore,a minimum deviation angle was pointed out during animation demonstration.In the course of teaching,the MATLAB program in the appendix can be displayed by the teacher.
