Following, the English physicists-Braggs 'obtained a simpler equation-the Bragg's law to show the relation of diffraction and made it easier to be accepted. 紧接着,英国物理学家布拉格父子又将此衍射关系用简单的布拉格定律表示,使之易于接受。
Based on the Bragg's law, the ordered TiO2 inverse opal films were successfully used as refractive index sensors with a resolution of0.01. 用这种二氧化钛反蛋白石光子晶体膜对溶液折射率的检测实验表明该传感膜分辨率可达0.01。
