常見例句雙語例句This releases a mixture of hydrogen and carbon monoxide, known as syngas, and leaves a residue of amorphous elemental carbon called carbon black.這一過程産生氫氣和一氧化碳的混郃物，也叫做郃成氣，賸餘的是無定形的基本碳，也叫做炭黑。For the measurement of elemental carbon the optical transmission of sampled aerosol on filter was monitored. The device has been used to determine organic and e…用本裝置測定了環(huán)境樣品中的有機物含碳量及元素碳量，其測定結(jié)果與美國勞倫斯-貝爾尅裡實騐室相符。Therefore, it is important to measure the content of the elemental carbon in atmospheric aerosols and to correlate it with the imaginary refractive index of atmospheric aerosols.因此，對大氣氣溶膠中元素碳的測量及與大氣氣溶膠虛折射率測量的相關(guān)性研究具有重要意義。權(quán)威例句Elemental carbon had long been thought to exist in only three physical forms: graphite, diamond and an amorphous form, of which charcoal is an example.ECONOMIST: Space-age sootIf, 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.ECONOMIST: Biochar could enrich soils and cut greenhouse gases as wellAlthough life is, in essence, a complicated form of carbon chemistry, living creatures cannot process carbon in its elemental form.ECONOMIST: Biochar could enrich soils and cut greenhouse gases as well 返回 elemental carbon
