夫琅和费型单缝衍射光强公式的修正

Modification for the Formula of Fraunhofer Diffraction on Single Slit

依据通常的夫琅和费型单缝衍射光强公式计算结果与实验结果有较为明显的歧异，其原因是在公式推导过程中忽略了衍射角和入射角变化所带来的影响．考虑到这些倾斜因素，对夫琅和费型单缝衍射光强公式做了理论上的修正，得出了更普遍更准确的光强公式．

There is large margin between normal diffraction strength formula with the resultof experiment of Fraunhofr diffraction on single slit. The reason is that the various of incident and diffraction angles is negected during the formula calculation. It is shown a modification result in this paper. A more general and more corrected result is obtained.
