【摘要】 提出用反应动力学的理论对ｎ型金属氧化物中的各类氧空位的浓度［Ｖ０×］，［Ｖ０＋］，［Ｖ０＋＋］的公式进行推导的方法，以［Ｖ０＋］＞［Ｖ０＋＋］的要求为依据，对一些金属氧化物费米能级ＥＦ的位置进行了估算．并对在气敏和在催化问题中金属和氧化物载体之间电子相互作用的规律作了讨论．更多还原

【Abstract】 The formulas of all kinds of oxygen vacancies concentration [V0×], [V0+],[V0++] in n-Type metal oxide is deduced by the method of theory of reaction kinetics. According to the requirement of [V0+]>[V0++], then estimates the position of Fermi Levels EF in some metal oxides. And makes the discussion about electronic interaction rule between metal and metal-oxide supports in some questions relative to the gas sensor and the catalysis.更多还原
