The variations of crystal thickness and refractive index will lead to a shift of synchronous Angle of Attenuated TotalReflection (ATR) spectrum, and then bring reflectance variation.
晶体厚度和折射率的变化导致衰减全反射(atr)谱的同步角发生移动,进而引起反射率的变化。

In order to reveal the aging mechanism, the analyses of infrared attenuated totalreflection (ATR), mass spectrum (MS) and pyrolysis gas chromatograph-mass spectra (PYGC-MS) were performed.
