This paper describes the study on the component and structure of the silicon oxide and silicon nitride films by infra-red absorbed spectrum. 利用紅外吸收譜等微觀分析對氧化硅和氨化硅薄膜的成分和結構進行了研究。
The absorption peaks arising from unsaturated and aromatic vibrations are considered in Chapter 3 and 5. 由不飽和以及芳香化合物振動產生的吸收譜帶將在第三和第五章中討論。
The ambers from the different localities may be of the same geological age, but exit the different ETIR absorption bands and strength according to the different polymeric grade. 不同產地的琥珀雖具有同樣的地質年代，但由於聚合化程度不同，其紅外吸收光譜峰的位置和強度存有差異。
