摘　　要：文献［１］提出“修改的边界衍射波理论”与“π跃变”的观点，本文用它计算了圆孔衍射场，却得不到与实际定量相符的结果。说明“π跃变”提法欠妥。The literatrue[1]has essentially revised the theory of boundary diffraction wave and declared an idea of 'π jump'. The author calculated the diffraction field of a circular aperture with this recised theory and conclude that the revised theory of diffraction can not obtain correct results quantitatively and point out that the 'π jump' idea is not suitable.
