摘　　要：在大学物理中,对圆孔衍射的讲解时,对于暗环衍射角公式一般都没有作详细的推导,只把它作为一个已知条件给学生,同时学生在实验室也很难做到精确测量圆孔衍射,或根本就没有做过圆孔衍射实验.为此,通过MATLAB对圆孔衍射做了精确的数值计算,同时利用MATLAB对圆孔衍射现象进行了演示.In the explanation of hole diffraction in College Physics, dark loop diffraction formulas arc generally not well deducted but given to students as a known condition. Meanwhile, students can hardly measure hole diffraction when doing experiments, and some students haven＇t done hole diffraction experiment at all. In this paper, by means of MATLAB, hole diffraction is accurately calculated and demonstrated.
