One may conclude that these two materials exist as a chemical mixture with distinct particles of lead oxide and lead . 人们可以认为这两种物质是作为一种化学混合物而存在的,它具有明显的氧化铅和铅的颗粒。
Other atmospheric pollutants such as oxidants and sulfur oxides may produce adverse cardiovascular effects, but the evidence is limited . 其他空气污染物,如氧化剂、硫氧化物可能对心血管产生有害影响,但这方面证据不多。
With regard to the oxide minerals, chromite is almost entirely contained in the olivine-rich ultramafic rocks in the lower part of the intrusion . 关于氧化矿物,铬铁矿几乎全部含于侵入体下部的富橄榄石的超镁铁质岩石中。
The effect of sulfur oxides could be anticipated from the earlier experience in the acute smog episodes described above and from the studies in great britain and japan . 硫氧化物的效应可根据上述早期的急性烟雾事件以及英国和日本的研究进行预测。
temperatures(around 950℃)will prevent stress-induced defect formation in a recessed structure(recess approximately land oxide growth approximately 2. 2μm). 温度在950上下就会避免在有凹槽的结构中形成应力诱发缺陷(凹槽约1m,氧化物层生长约22m)。
