Oxygen

氧气

Oxygen is the most abundant element in the earth's crust, making up about 46.6% by weight of the crust. It constitutes 89% of water by weight, 23% of the air, and nearly 50% of common silicate minerals. It is also present in carbonate, sulfate and phosphate minerals as well as in oxide minerals. As a gas, it exists as a diatomic molecule O₂.

氧是地壳中含量最多的元素，占地壳重量的约46.6%。它占水重量的89%，占空气的23%，并占常见硅酸盐矿物的近50%。它还存在于碳酸盐、硫酸盐和磷酸盐矿物以及氧化物矿物中。作为气体，它以双原子分子O₂的形式存在。

Ordinary combustion is the process of combining oxygen with other substances. The energy required for bodily warmth and the physical and chemical process of living organisms is obtained from the combination of oxygen with organic material in food.

普通燃烧是将氧气与其他物质结合的过程。生物体维持体温所需能量以及生命活动的物理和化学过程，来自于食物中有机物质与氧气的结合。
