采用热脱附（TD）、电子激发脱附（ESD）、光子激发脱附（PSD）、X射线光电子能谱（XPS）和扫描电镜（SEM）研究了D2 O和H2O在铁氧化物薄膜表面的吸附和脱附行为。当加热速率为5 K/min时，吸附态D2 O在400 K和600 K左右脱附。吸附的D_2O加热到773 K不能解吸，可通过光子辐照或电子轰击解吸。
Adsorption and desorption of D2O or H2O, as a simulator of HTO, on iron surface covered with thin iron oxide film were studied by thermal desorption (TD), electron stimulated desorption (ESD), photon stimulated desorption (PSD), X-ray photoemission spectroscopy (XPS), and scanning electron microscopy (SEM). When the iron was heated under constant heating rate (5K/min), adsorbed D2O was desorbed around 400K and 600K. Adsorbed D2O which could not be desorbed by heating to 773K could be desorbed by irradiation with photon or bombardment with electron.
