The oxidation curve and sem images show that the oxygen evolution at the interface plays a key role in the transition from the compact al oxide layer to the porous membrane 分孔道的產(chǎn)生說明析氧反應(yīng)不但在致密膜電解液界面發(fā)生,而且在多孔膜孔壁電解液界面也同時發(fā)生。
The contributions of non - leaf organs to photosynthesis next , studies on photosynthetic pigment , the rates of photosynthetic oxygen evolution and 77k fluorescence emission spectrum of awns and lemmas in rice and wheat were carried out 隨著小麥芒的衰老過程,其中葉綠體的數(shù)量也隨之減少,并且這種減少的趨勢在旗葉中先發(fā)生。
Some researches have been carried out to learn about the oxygen evolution properties of rumn , ruco , ruce and rueu etc in haso ^ solution , and their electro - catalysis towards methanol oxidation if added into the anode coating 實驗研究了rumn , ruco , ruce和rueu等在硫酸溶液中的析氧性以及它們被添加到pt / ti電極陽極涂層中后對甲醇的電催化作用。
The result indicates that the anode coating containing the powerful oxygen evolution metal oxide such as rumn , ruco or rueu exhibit a higher electro - catalytic activity than pt / ti electrodes without metal oxides in coating 結(jié)果表明鉑涂層中添加rumn , roco和rueu等強析氧性金屬氧化物后,同涂層中不含金屬氧化物的pt / ti電極相比,對甲醇電氧化顯示了更高的催化活性。

百科解釋
Oxygen evolution is the process of generating molecular oxygen through chemical reaction. Mechanisms of oxygen evolution include the oxidation of water during oxygenic photosynthesis, electrolysis of water into oxygen and hydrogen, and electrocatalytic oxygen evolution from oxides and oxoacids.
