查询词典 dioxide

Sulfur dioxide is one of primary air pollutant.

二氧化硫是造成大气污染的主要因素之一。

The United States is the world's largest polluter, accounting for 25% of all carbon dioxide emissions, a major cause of global warming, despite its population of just 4% of the world's total.

美国是世界上最大的污染排放国，尽管它的人口只占全球人口的百分之四，但二氧化碳排放量占全球总排放量的25%，而二氧化碳排放是引起全球变暖的主要原因。

Moreover, the effects of nano silicon dioxide (SiO2) particles and nano SiO2-g-PBA composited particles on the of polyoxymethylene were studied by means of mechanical properties test, scanning electron microscope and TEM.

力学性能、扫描电子显微镜及透射电子显微镜等测试表明：纳米SiO2在POM中团聚明显，而SiO2-g-PBA纳米复合粒子POM中分散均匀，导致POM/SiO2-g-PBA纳米复合材料的缺口冲击强度明显高于POM及POM/SiO复合材料，当SiO2-g-PBA纳米复合粒子的质量分数为2%时，POM/SiO2-g-PBA复合材料的冲击强度是POM的8倍多，同时拉伸强度有一定的增加。
