1·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。
2·As the principal component in glass, silicon dioxide was used as early as 5000 BC.
作为玻璃的主要成分，二氧化硅早在公元前5000年就被使用。
3·It's puzzling to try to understand why their chili would need to include an anti-caking agent such as silicon dioxide (also known as sand, or glass powder).
它很令人费解，为何他们的辣椒需要包括一个防结块的物质，如二氧化硅(也称为砂，或玻璃粉末)。
4·Or rather, it's slang for the disease you get when you inhale silicon dioxide which makes it hard to breathe.
或者，当你因为吸入二氧化硅而难以呼吸时所得疾病的俚语称谓。
5·Normally, silicon carbide is produced by heating sand (which is made of quartz, or silicon dioxide) in an electric furnace with carbon made from oil or coal.
通常，硅碳化合物通常由加热的沙子(通常由石英构成，或称二氧化硅)和石油或煤炭中提取的碳放在电气炉内反应而得到。
