The results show that the surface layer of the air-exposed ZrVFe getter is covered with H20, CO2 and hydrocarbons, both Zr and V exist in the oxidized state, and vanadium oxide starts to reduce at 200℃. The activation results in the enrichment of Zr on the getter surface and the formation of the metallic carbides. H2O, CO2 and hydrocarbons sequentially desorb from the surface with the increase of temperature. H2 is the main gas which desorbs above 200℃ and O2 is not discovered. ZrO2 is reduced to near-metallic or metallic state because O in ZrO2 leaves the getter surface through diffusing into getter bulk.

结果表明：暴露于过大气的吸气剂表面覆盖着H2O、CO2及碳氢化合物等，Zr和V主要以氧化态存在；在吸气剂加热激活过程中，V的氧化物在200℃开始还原；激活过程导致表面近金属态Zr的富集以及部分金属碳化物的生成；随着温度的升高，H2O、CO2及碳氢化合物逐渐从吸气剂表面脱附，在200℃以上，主要脱附气体为H2，整个激活过程未发现O2；ZrO2还原为近金属态或金属态，主要是由于ZrO2中的O通过向吸气剂内部扩散而离开吸气剂表面所致。
