Each crystal structure consists of alternating layers of silicon dioxide and a polymer material, so that the spacing between similar layers matches the wavelength of phonons.
每个晶体结构由相间的二氧化硅层和高分子聚合材料层组成，相同材料层之间的间距与声子的波长相匹配。

The polymer spheres and carbon particles arrange themselves spontaneously into the correct crystal structure when encouraged by a little heat, so manufacturing opalescent film should be easy.
只要加入一点聚合体球体和碳颗粒就可以自然地安排成正确的晶体结构，因此生产光亮的薄膜就很容易了。
