Liquid oxygen storage requires specific regulations to be known and respected 液氧貯罐需要有特別的規(guī)[定,并清楚規(guī)定的內(nèi)容,遵守該規(guī)定。
When 20 % ( wt ) polymerb was added , the oxygen storage materials get the most ideal synthesis properties 比較發(fā)現(xiàn),以聚合物b的添加量為20 ( wt )時(shí),所得儲(chǔ)氧材料的綜合性能最佳。
In present paper , the influence of additives and preparation methods on the performance of oxygen storage materials was studied in detail 本文詳細(xì)研究了元素e和m的添加,聚合物的添加以及制備方法對(duì)ceo _ 2 - zro _ 2固溶體的影響。
Main physical and chemical processes including heat and mass transfer , flow distribution , chemical kinetics , oxygen storage and catalyst deactivation are discussed 討論了催化轉(zhuǎn)化器中主要的物理和化學(xué)過程,包括傳熱傳質(zhì)、氣流分布、化學(xué)動(dòng)力學(xué)、儲(chǔ)氧和催化劑中毒。
The appropriate addition of polymers into oxygen storage materials can improve the osc obviously and can make the samples become high - temperature - resistant materials with favorable surface area even after aged at high temperature 研究表明適量聚合物的添加可以明顯提高儲(chǔ)氧材料的儲(chǔ)氧性能和抗高溫老化性能,使樣品在老化前后的比表面積得到更好的保持。
