| 摘 要： | 实验中发现平面衍射光栅各级明条纹的亮度随衍射角和入射角的变化而变化，这与理想状况下光强公式存在较为明显的歧离，其原因是公式推导过程中忽略了入射角和衍射角变化所带来的影响，考到这些倾斜因素．对平面衍射光栅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。

| Abstract: | There is large margin between normal diffraction strength formula with the result of experiment of plane diffraction grating.The reason is that the various of incident and diffraction angles is neglected during the formula calculation.It is shown a modiffication result in this paper.A more general and more corrected result is obtained. |

| Keywords: | diffraction grating optic intensity |
