应用振幅矢量法讨论夫琅和费单缝衍射光强分布

Discussion of insensity distribution for Fraunhofer Single-Slit diffraction by method of amplitude vector

本文提供了夫琅和费单缝衍射（简称衍射，下同）光强计算公式，与一般文献中的理论公式相比，不但完全等效，而且计算简便精确，对衍射光强分布的实际应用及实验测量￣［３］具有一事实上的参考价值。

This paper puts forward formulas concering the intensity distribution for Fraunhofer Sin-gle-Slit diffraction.Compared those with intensity formula in current literatures,they are not only wholly equivalent but also simple and precise in calculation. They are valuable for reference to practical application and experimental measurement of the diffractional intensity.
