摘　　要：利用数值分析的方法分析了由边界波理论公式所得的圆形光阑衍射场的光强分布 .通过对边界波理论公式所得的光强分布曲线 ,对几何照明区与阴影区的光强分布曲线与面衍射积分公式所得的光强分布曲线进行比较 。The light intensity distribution of diffraction of circular aperture was investigated by numerical analysis.In the case of the light intensity distribution function according to the boundary diffraction wave theory formula scaled along the axis direction of light intensity respectively in the shadow zone and the geometrical zone,then by comparing the above light intensity distribution curse and one directly by using the dualistic integral,the accuracy of the boundary diffraction wave theory formula was analyzed in some certain areas.
