NO2 is the main source of nitrate aerosols, which form an important fraction of PM2.5 and, in the presence of ultraviolet light, of ozone.
臭氧提供天然的保护，防止太阳的有害紫外线的侵害，这种紫外线会导致晒斑，白内障，皮肤癌以及危害植物。
Ozone provides a natural protective filter against harmful ultra-violet rays from the sun, which can cause sunburn, cataracts and skin cancer as well as damage vegetation.
缺少了臭氧层对太阳紫外线辐射的抵挡，人类将有可能被迫过起“吸血鬼”般的生活——白天只能躲在屋子里。
The massive loss of protection against the sun's ultraviolet (UV) radiation would likely force humans into a vampire-style existence of staying indoors during daylight hours.
一个可能的原因是臭氧耗竭或云层高度改变引起紫外线辐射增强。
A likely candidate is rising ultraviolet radiation as a result of either ozone depletion, or a change in the level of cloud cover.
平流层大气包含臭氧层，臭氧层由紫外线照射导致的三个氧原子结合成的臭氧分子组成。
The still air of the stratosphere contains the ozone layer, which was created when ultraviolet light caused trios of oxygen atoms to bind together into ozone molecules.
为了对付这些病菌，LM系统的末端通常会配有紫外线、臭氧或者氯等的消毒装置。
To deal with this, the Living Machine often includes components at the end of the system that sterilize the water with ultraviolet radiation, ozone or chlorine.
科学家们相信灼伤是因为臭氧层变薄，致使紫外线辐射等级增加而引起的。
Scientists believe the sunburns are due to increasing levels of ultraviolet radiation resulting from the thinning ozone layer.
美国大部分的饮用水都由污水处理厂使用氯、臭氧、或紫外线等过滤处理。
Most of the country's drinking water is treated using chlorine, ozone, or UV rays at municipal filtration plants.
臭氧层可以保护地球上的生物免受有害紫外线的辐射。
The ozone layer protects life on Earth from harmful ultraviolet rays.
当臭氧层消失时，更多的紫外线辐射到达地球表面。
As the ozone layer is depleted, more UV radiation reaches the Earth's surface.
最后一项变冷效应是由于平流层臭氧减少所致，而臭氧可抑制平流层从太阳吸收紫外线。
This last cooling effect is caused by a decline in ozone in the stratosphere which prevents it absorbing as much ultraviolet radiation from the sun above.
晒伤增多的一个原因可能是臭氧层空洞，而臭氧层是保护地球不受太阳紫外线危害的保护层。
One reason for the rise in sunburn could be the hole in the ozone layer - the protective layer that shields the Earth from the sun's harmful ultraviolet rays.
臭氧：臭氧吸收一些太阳紫外线辐射。
地球臭氧层位于平流层，过滤来自太阳的紫外线辐射。
This is where the planet's ozone layer sits, filtering out ultraviolet radiation from the sun.
更多的紫外线到达平流层意味着会有更多的臭氧生成，而更多的臭氧则会导致平流层吸收更多的紫外线。
More ultraviolet light reaching the stratosphere means more ozone is formed. And more ozone leads to the stratosphere absorbing more ultraviolet light.
太阳光中的紫外线会损伤动植物(包括人类)的DNA和引起皮肤癌，而臭氧层的功能就是阻挡住这些有害的紫外线从而保护地球上的生命。
Earth's ozone layer protects life by absorbing ultraviolet light, which damages DNA in plants and animals (including humans) and leads to skin cancer.
