衰减全反射红外光谱技术是表层结构分析的有利手段。
Attenuated total reflection infrared spectroscopy (ATR) is a useful tool for surface analysis providing structural and chemical information about the sample.
对照全反射红外光谱和透射红外光谱的分析结果，从而确定样品中间层的成分。
The analysis results from the fully reflective infrared ray test and that from the transmission infrared ray test are compared to determine the component of the intermediate layer of the sample.
若是多层不同材质，先对样品的上下表面进行全反射红外光谱测试，确定上下表层成分。
If the structure is of multi layers, first the upper and the lower surface of the sample go through fully reflective infrared ray test; the components of the upper and lower surface are determined.
