If, however, they are subjected instead to pyrolysis-a process of controlled burning in a low-oxygen atmosphere-the result is charcoal, a substance that is mostly elemental carbon.

但如果经过高温分解—在低氧环境下有控制的燃烧—它将会形成木炭，其大部分是永久碳。

The energy of the Sun arises not from any burning process but from nuclear fusion, the transformation of hydrogen into helium, in part by a complicated process involving carbon and nitrogen.

大阳的能量不是来自燃烧过程，而是来自由氢到氦的核聚变，是部分由一个涉及碳和氮的复杂过程引起的。

Biomass combustion process is mainly concentrated on the burning of volatile combustion in the early stage, while coal combustion process focused on the burning of fixed carbon in the later stage.

生物质燃烧过程主要集中在燃烧前期的挥发分燃烧阶段，煤燃烧过程主要集中在燃烧后期的固定碳燃烧阶段。

The bioreactors will grow algae that can produce ethanol fuel through a special process that involves using carbon dioxide from nearby coal-burning power plants to promote faster growth of the algae.

As well as destroying such native ecosystems, deforestation also diminishes so-called "carbon sinks" -- thereby reducing the Earth's capacity to absorb and re-process atmospheric carbon dioxide -- while also adding to air pollution through the burning of land to clear it for cultivation (sugarcane fields are traditionally fired prior to harvest to remove leaves and drive away snakes).
