这些燃烧过程同样释放化学物质如甲烷、氮氧化合物、挥发性的有机化合物和一氧化碳在光照下反应形成臭氧。

These same processes also release chemicals that combine in sunlight to form ozone: methane, nitrogen oxides, volatile organic compounds, and carbon monoxide.

但由于镁的化学性质活泼，非常容易氧化、燃烧，导致镁合金无法在大气条件下直接进行熔炼和浇注。

Since its chemical character is very active, Mg alloy is prone to oxidation and burning, which makes it impossible to be melted and cast in air.

由于燃烧是一个氧化过程，所以烧毛可以被认为是一个化学过程。

Since burning entails oxidation, this process may be thought of as a chemical process.
