摘　　要：分析比较了Kirchhoff—Fresnel(K—F)和Rayleigh—Sommerfeld(R—S)衍射公式之间的差异.用实验测得单缝衍身的光强分布与理论曲线比较,结果表明R—S衍射公式与实际相吻合,而K—F衍射公式在衍射狭缝较小衍射角较大时与实际有较大的差异.The differences between Kirchhoff—Fresnel diffraction formula and Rayleigh—Sommerfe diffraction formula are pointed out. The coincidence of Rayleingh—Sommerfeld formula and t reality is verified. But the Kirchhoff—Fresnel formula is far from reality, specially when slit small and diffraction angle is large.
