- 1臭氧（臭氧層 = ozone layer）
Ozone is a type of gas. Its molecules are made of three oxygen atoms stuck together, instead of the usual two. High up in the sky, a thin layer of ozone protects us from the sun's harmful rays — people call this "the ozone layer." Near the ground, ozone is actually a kind of pollution and can be bad for our lungs. People also say the air by the sea smells "of ozone," meaning fresh and salty — though what they smell is not really ozone at all.
From the word’s history
From German Ozon, coined 1840 by Schönbein from Ancient Greek ózon, participle of ózō 'I smell', for its pungent odour.
借自德文 Ozon，1840 年取希臘文「我聞到」造出，指它的刺鼻氣味。
組成From a Greek word meaning "to smell" — ozone has a sharp smell, and that is how it got its name.
