摘　　要：结合教学实际情况,为了在有限的学时内使学生能较好地理解光栅衍射条纹分布特点,通过振幅矢量法与半波带法分析光栅衍射的比较,提出用半波带法分析光栅衍射是可行的简化方法。因为在学习光栅衍射之前学生已学习了用半波带法分析单缝衍射,所以用半波带法分析光栅衍射,能够使学生较易于理解。To make students have a clear understanding the stripe distributing character of grating diffraction in limited lecture-time on the basis of teaching condition, this essay shows that 'half-wave spectrum method' to analyze grating diffraction is feasible and simple compared to 'amplitude vector method'. Half-wave spectrum method is easier for the students to understand because they have already known how to use 'half-wave spectrum method' to analyze single-slit diffraction before they learn grating diffraction.
