We analyze the theory of attenuatedtotalreflection (ATR) and find the coupling method to excite the SPR and introduce the coupling type of the SPR sensor.
The variations of crystal thickness and refractive index will lead to a shift of synchronous Angle of AttenuatedTotalReflection (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 attenuatedtotalreflection (ATR), mass spectrum (MS) and pyrolysis gas chromatograph-mass spectra (PYGC-MS) were performed.
