氧是维持人类生命的四大要素(阳光、空气、食物和水)之一。人可以停吃三餐饭,但不能3分钟不吸氧。人一旦断了空气(正常空气中含氧20.95%),就会马上死亡,因此氧气被称为“生命之气”、“救命之气”、“养身之气”。看来,我们的老祖宗的确很会造字,而且造得很科学、很形象,造出这么一个“氧”字。氧是维持人体生命活动的必要物质之一,生物氧化是人体能量的根本来源,为了
Oxygen is one of the four major elements (sunlight, air, food and water) that sustains human life. People can stop eating three meals, but not three minutes without oxygen. Once people cut off the air (20.95% of the oxygen in normal air), they will die immediately, so oxygen is called “the gas of life”, “the gas of life-saving”, “the energy of keeping one’s health”. It seems that our ancestors did create words and made very scientific and vivid images of such an “oxygen” word. Oxygen is one of the necessary substances to maintain the life activities of human beings. Biological oxidation is the fundamental source of energy for the human body.
