After purging, oxygen pulses are injected until the detection system no longer indicates oxygen adsorption . 脫氧后,注射氧脈沖直到測檢系統(tǒng)表明不再有氧吸附為止。
Method for identifying tendency of coal to spontaneous combustion by oxygen adsorption with chromatograph 煤自燃傾向性色譜吸氧鑒定法
The authors measure their electrical transport properties in air and in vacuum respectively and find that the electrical transport of sodium titanate nanowires devices is affected . this is attributed to oxygen adsorption on the surface of nanowire 分別在大氣和真空兩種環(huán)境下測量了該器件的電學(xué)特性,發(fā)現(xiàn)器件所處的氣體環(huán)境可以影響其電傳輸特性,這可能是由于納米線表面的氧分子吸附造成的。
The results indicate that the osc and reductibility of the ceo2 - zro2 solid solution are not improved after adding e ions . while after incorporating m ions into the ceo2 - zro2 , the samples exhibit high osc probably by reason that m - o itself also has good capability of oxygen adsorption . after aged at high temperature , the osc of these samples decreased dramatically for the formation of m2o3 and mo2 and for the separation of tetragonal phase of ceo2 - zro2 在ceo _ 2 - zro _ 2固溶體中引入m后,由于m - o本身具有氧吸附性能,使得樣品表現(xiàn)出很好的儲氧能力,但經(jīng)過高溫老化后,原四方晶相的ceo _ 2 - zro _ 2固溶體發(fā)生了相分離,且生成了大量的m _ 2o _ 3和mo _ 2相,使得樣品的儲氧量急劇減少,可還原性能明顯降低。
