衍射环 [yǎn shè huán]
[光] diffraction ring
- 其电子衍射具有稀疏的斑点和较少的衍射环。
The scattered diffraction pattern and smaller rings were shown in the electronic diffraction analysis through TEM. - 举头仰望湛蓝的天空，你将不时地看到眼球里的漂浮物，包着一圈淡淡的衍射环；
Looking upward into a clear blue sky, you will occasionally notice floaters in your eye surrounded by tiny diffraction rings. - 按照这个方法，用衍射环间距取代了传统方法中的半径。
Using this method the substitution of distance between diffraction rings for the radii of rings results in a very considerable reduction in centre error.
