air
空气
Air is the gas mixture in the Earth's atmosphere. It consists essentially of 78% nitrogen, 21% oxygen, and 1% mixture of rare gases and impurities. The composition of the air is not fixed, with the height of the change, the pressure changes, the proportion of air composition will change. But for a long time people have always thought that the air was a single substance until the French scientist Lavoisie passed the experiment first to conclude that the air was composed of oxygen and nitrogen. At the end of the 19th century, scientists also found a lot of experiments, the air there are helium, argon, xenon and other rare gases. In the natural state the air is tasteless and odorless. Oxygen in the air is necessary for all aerobics. All animals need to breathe oxygen. In addition, plants utilize photosynthesis of carbon dioxide in the air, and carbon dioxide is the only source of carbon for almost all plants. ... 空气是指地球大气层中的气体混合。它主要由78%的氮气、21%氧气、还有1%的稀有气体和杂质组成的混合物。空气的成分不是固定的，随着高度的改变、气压的改变，空气的组成比例也会改变。但是长期以来人们一直认为空气是一种单一的物质，直到后来法国科学家拉瓦锡通过实验首先得出了空气是由氧气和氮气组成的结论。19世纪末，科学家们又通过大量的实验发现，空气裡还有氦、氩、氙等稀有气体。 在自然状态下空气是无味无臭的。 空气中的氧气对于所有需氧生物来说是必须的。所有动物需要呼吸氧气。此外植物利用空气中的二氧化碳进行光合作用，二氧化碳是近乎所有植物的唯一的碳的来源。...
The general term for the air surrounding the earth in the atmosphere. It is one of the important material conditions for all life on Earth to survive. Together with the ocean and land, the earth system is formed. It is the key to the momentum, heat and material circulation in the earth system. The total mass of the atmosphere is about 53 × 1018 kg, accounting for about one millionth of the total mass of the earth. The lower atmosphere consists of nitrogen, oxygen, water vapor, ozone, carbon dioxide and other components. The density declines and tends to lean as the ground height increases, generally defining the atmosphere 1000 km above the ground. 大气 包围地球的空气的总称。是地球上一切生命赖以生存的重要物质条件之一。与海洋、陆地共同构成地球体系。是地球体系中动量、热量与物质循环的关键。大气总质量约53×1018千克，约占地球总质量的百万分之一。低层大气由氮、氧、水汽、臭氧、二氧化碳等组成。密度随距离地面高度的增加而下降并趋于稀薄，一般将大气上界定为距地面1000千米处。
