氧传感器的测氧方法是在氧化锆电解质(ZrO2)管的两侧面分别烧结上多孔铂(Pt)电极，在一定温度下，当电解质两侧氧浓度不同时，高浓度一侧(Ⅱ侧Pref)的氧分子被吸附在铂电极上与电子(4e)结合形成氧离子O2-，使该电极带正电，氧离子通过电解质中的氧离子空位迁移到氧浓度低的一侧（Ⅰ侧PO2）的Pt电极上放出电子，转化成氧分子，使该电极带负电。Makeing dumpling is really teamwork .Usually all family members will join the work .Some people starte to make dupling when they were kids in the family ,so most chinese know how to make dumpling .
