1、That is why, by day,ozone is hard to get rid of.(这就是白天空气中臭氧难于消散的原因。)
2、So, let's quickly go through the Lewis structure forozone.(那么，让我们很快地画出臭氧的路易斯结构。)
3、Breathing in too muchozone can cause lung damage.(吸入过多的臭氧会导致肺损伤。)
4、Theozone layer shields the earth from the sun's ultraviolet rays.(臭氧层保护地球不受太阳紫外线的辐射。)
5、It is widely known that CFCs can damage theozone layer.(众所周知氯氟烃会破坏臭氧层。)
6、ozone (O3)(臭氧（O3）)
7、The destruction of Earth'sozone layer, for example, could contribute to the general process of impoverishment by allowing ultra-violet rays to harm plants and animals.(例如，地球臭氧层的破坏会使紫外线伤害植物和动物，从而导致普遍的贫困进程。)
8、But theozone layer is not yet safe.(但是即使如此，臭氧层依然没有获得安全保障。)
9、ozone harms plants, which decreases food production.(臭氧对植物有害，会造成粮食减产。)
10、These are pollutants, particularlyozone and soot, that do not hang around in the atmosphere as carbon dioxide does.(这些污染物，尤其是臭氧和煤烟，不像二氧化碳那样悬浮在大气中。) 【hao86.com好查】
11、Theozone layer screens out dangerous rays from the sun.(臭氧层能遮挡住来自太阳的有害射线。)
12、ozone is produced by the reaction between oxygen and ultraviolet light.(臭氧是氧气与紫外线发生化学反应而产生的。)
13、The machine uses minute quantities ofozone to sterilize and deodorize refrigerated food vehicles.(这个机器用微量臭氧对食物冷藏车进行消毒和除臭。)
14、The absence of oxygen on other planets means that those planets lack anozone shield to protect life forms against UV radiation.(其他行星上没有氧气，这意味着这些行星缺乏保护生命体免受紫外线辐射的臭氧层。)
15、The absence of an oxygen atmosphere on Mars and other planets in our solar system means that these planets also lack anozone shield that would protect surface-dwelling life from UV radiation.(在火星和我们太阳系的其他行星上没有氧气，这意味着这些行星也缺乏保护地表生物免受紫外线辐射的臭氧层。)
16、In heavy concentrations,ozone is irritating to the eyes, nose and throat.(浓度极高时，臭氧对眼睛、鼻子和喉咙是有刺激的。)
17、They will press for international action to safeguard theozone layer.(他们将竭力要求国际行动来保护臭氧层。)
18、The size and shape of theozone hole is shown in 2009.(这幅图片上的阴影显示的是2009年的臭氧层空洞。)
19、Because early Earth lacked oxygen in its atmosphere, it also lacked a protectiveozone barrier.(因为早期的地球大气中缺乏氧气，所以也缺乏起保护作用的臭氧层屏障。)
20、These molecules burn more cleanly than gasoline, in part because they have fewer, if and, carbon-carbon bonds, and the hydrocarbons they do emit are less likely to generateozone.(这些分子燃烧起来比汽油更清洁，部分原因是它们的碳-碳键更少或者不存在，而且它们排放的碳氢化合物产生臭氧的可能性更小。)
21、ozone is the earth's barrier against ultra-violet radiation.(臭氧是地球防止紫外线辐射的屏障。)
22、ozone forms a protective layer between 12 and 30 miles above the Earth's surface.(臭氧在距地球表面12至30英里的地方形成一个保护层。)
23、ozone is more prevalent in places distant from highways.(臭氧在远离公路的区域更为普遍。)
24、ozone is a highly reactive form of oxygen gas.(臭氧是一种高度活跃的氧气形态。)
25、I smelled and tastedozone.(我闻到和品尝了臭氧的气味。)
26、What they find could provide clues to what might happen worldwide ifozone depletion continues.(如果臭氧的损耗继续下去，他们的发现能为全世界可能发生的情况提供线索。)
27、These molecules burn more cleanly than gasoline, in part because they have fewer, if any, carbon-carbon bonds, and the hydrocarbons they do emit are less likely to generateozone.(这些分子燃烧起来比汽油更干净，部分原因是它们的碳-碳键更少（如果有的话），而且它们排放的碳氢化合物不太可能产生臭氧。)
28、And when sunlight hits those compounds,ozone forms.(而当阳光照射在这些物质上时就会产生臭氧。)
