| 摘 要： | 在光的衍射实验中，一般看到的是由通过衍射片的直射光形成的衍射图样，但在衍射片的另一面，同样存在着另一个衍射图样，它是由衍射片的背面反射光形成的，两个衍射图样关于衍射片对称．文章给出了这种实验现象，并用巴比涅原理解释了这种现象．

| Abstract: | In the experiment of diffraction of light, we can notice the diffraction pattern formed from the point--blank light. But in another side of the diffraction screen, we can notice another diffraction pattern formed from the reflection light of the back of the diffraction screen too. And the two diffraction patterns are symmetrical on the diffraction screen. This article is to show the experiment phenomena, and explain the phenomenon with the Babinet principle. |
