摘　　要：根据半波带法的思路 ,介绍了利用计算机课件演示对单缝夫琅和费衍射的条纹光强与衍射角之间的关系 ,以便有效地化解教学难点 ,帮助学生对该知识点形成清晰的认识和深化理解 ,同时对课件制作要点作了简要说明 .Based on the half-wave belt theory, we demonstrated the relation between the intensity distribution of single-slit Fraunhofer diffraction and its direction using CAI software. It would help students to understand the phenomena easily. Even more, we briefly explained the making of CAI software.
