摘　　要：对环形光栅的Ｆｒａｕｎｈｏｆｅｒ衍射场进行了详细的理论研究．给出了衍射光强的一般表达式和确定光强权大值及零点位置的自洽方程．应用电子计算机对衍射场进行了数值模拟，计算结果与实验值相符．The Fraunhofer diffraction of grating with circulary concentric rings is studied in detail. The intensity distribution of the diffraction field is given. The self-consistent equations of the positions for relative intenstities of maxima and minima are obtained. The results of some numerical simulation on computer conform to the experimental facts.
