利用微量吸附量热技术定量地表征了Ｅｕ２Ｏ３、ＣｅＯ２、ＭｇＯ、ＺｎＯ、Ａｌ２Ｏ３和ＮｉＯ等氧化物表面酸碱中心的强度和数量，结果表明，样品的ＮＨ３和ＣＯ２起始吸附热与其Ｓａｎｄｅｒｓｏｎ电负性相关．
The intensity and amount of acid-base centers on the surface of oxides such as Eu2O3, CeO2, MgO, ZnO, Al2O3 and NiO were quantitatively characterized by means of micro-adsorption calorimetry. The results showed that the initial adsorption heat of NH3 and CO2 was negatively correlated with the Sanderson electronegativity Related.
