有关地球大气中臭氧层减少的国际讨论已持续了 30多年。科学家们还到极地考察,搜寻资料进行研究。所谓臭氧层就是大气平流层中臭氧集中的地区,其中臭氧浓度最大部份位于20-25千米的高空,是由太阳紫外线的光化作用所致;并且太阳幅射的紫外线绝大部份也被臭氧层吸收。因此,臭氧有保护地球上生物的作用。臭氧的化学分子式为O3。
International discussions on the ozone layer depletion in the Earth’s atmosphere have been going on for more than 30 years. Scientists also visited the polar regions to search for information for research. The so-called ozone layer is the concentration of ozone in the stratosphere of the atmosphere, of which the largest portion of the ozone concentration is located at an altitude of 20-25 km, which is caused by the actinization of the sun’s ultraviolet rays; and most of the ultraviolet radiation from the sun is also Ozone absorption. Therefore, ozone has the role of protecting the life on Earth. The chemical formula of ozone is O3.
