蓝宝石上覆盖奈米管后，就可在任意的位置安装电晶体的金属电极，再以高度离子化的氧气除去不需要的奈米管。 - the combustion of c2h2 with oxygen gas will yield earbon dioxide and water, calcutate the % yield of carbon dioxide when 13 grams of c2h2 are burned with oxygen which is in excess and 33 grams of co2 was formed
乙炔在氧气中燃烧产生二氧化碳和水,当13克乙炔在足量氧气中燃烧产生33克二氧化碳,求二氧化碳的产率 - it was concluded that the effect of process parameters on the structural electrical and optical properties of zao films had great influence . in addition zao films were also deposited in a mixed argon and oxygen gas, through this way, the effects of oxygen on the properties of the films were studied
结果表明成膜过程中各工艺参数对其结构和光电特性存在较大的影响，另外还采用了在氩气和氧气的混合气氛中制备铝掺杂的氧化锌薄膜，以此研究了溅射过程中氧气分压的作用。 - it is not clear that how different enriched oxygen gas protects aircrew and passenger during emergency oxygen supply, especially, under the condition of passenger's mask not hermetic in 12 000m high altitude, and whether molecular sieve oxygen generation system ( msogs ) can vi be used above 8 500m . these problems are all need molecular biological proof
在现代航空飞行员和乘客的防护问题上，高空应急供氧时间内不同供氧水平对机体的影响尚不清楚，如12000m高度旅客面第四军医大学硕士学位论文罩不气密时供氧防护效果，以及采用分于筛供氧能否提高适用高度等问题，急需从分子生物学水平提供理论参考。 - the result of experiment showed that the reaction between ti and c is a thermodynamic course, when 2 wt % mg is added to melt, it can restrain the formation of fragility phase al3ti, and gained al matrix composite which contained tic reinforced particles only . because mg reacts with the forms a micro-high temperature field around the oxide around the graphite particles and the oxygen gas which is brought by the immersion bell, and the reaction gives out a lot of heat energy, thus forms many high micro-fields in melt, which prompt the reaction between the al and ti
加入适量的mg(2wt)可以抑制tical复合材料中的脆性相al_3ti的产生，生成仅含tic的铝基复合材料；由于活化剂镁在体系中与石墨颗粒周围的氧化物、以及外来的氧反应放热，在熔体中形成微高温区，促进al-ti反应，同时，al-ti反应也是放热反应，因此体系中的内能急剧增大，促使al_3ti分解以及ti朝c颗粒扩散，缩短反应的孕育时间。 - meanwhile, the structural stability of delithiated cathode materials is also improved by ti doping . it results in the suppression of thermal decomposition reaction of delithiated cathode material, which will produce heat and oxygen gas as the fuse of electrolyte decomposition and combustion reaction . hence, thermal stability of delithiated cathode material is also enhanced by ti doping
同时，钦的掺杂增强了电极材料在脱铿状态下的结构稳定性，抑制了电极材料自身热分解反应的发生，阻止了氧气和热量的释放，减少或延迟了电解液的分解或燃烧反应，从而提高了电极材料的热稳定性。
