摘　　要：在分光计测量三棱镜顶角实验中,改进了传统的方法,即对分光计进行二次调整.结果误差明显减小,提高了测量精度.In measuring angle of the prism by the spectrometer, there are rather large error in the traditional experiment method is improved. The experiment is modified by operating the spectrometer once more so that errors are reduced and measuring precision is improved.
