Can the state of mixing of black carbon aerosols explain the mystery of ‘ excess ' atmospheric absorption 解釋‘過度’大氣吸收的秘密能說明碳黑氣溶膠混合狀態(tài)嗎?
Industrial pollution brought a seven - fold increase in soot - also known as black carbon - in arctic snow during the late 19th and early 20th centuries , scientists at the desert research institute found 工業(yè)污染帶來了七倍的煙塵? ?像我們知道的炭黑? ? ?極地研究所的科學(xué)家們從19世紀(jì)末到20世紀(jì)初在北極的雪中發(fā)現(xiàn)了。
Besides humic acid and kerogen , four soms consist of a special organic fraction black carbon ( bc ) , it accounts for the least 18 . 36 % of toc in marine sediment . and different fractions of som have different origin 四種土壤和沉積物有機質(zhì)中除了腐殖酸和干酪根,都含有相當(dāng)數(shù)量的碳黑,最少的海洋沉積物有機質(zhì)中碳黑含量也達到18 . 36 。
The aromatic carbon increasing from humic acid , kerogen to black carbon , and structure become more condensed , rigid , and stable . in addition , we also characterized the residue after py - gc - ms , which show it structurally rigid and physically condensed 另外,我們還對py一gc一ms分析時產(chǎn)生的含碳?xì)堄辔镞M行了結(jié)構(gòu)表征,表明它具有高度芳香性的結(jié)構(gòu),十分穩(wěn)定。
Bc asphaltenes similar to petroleum asphaltenes and consist of aromatic nuclei , aliphatic chains , and naphthenic ring structures combined in three - dimensional network . but black carbon asphaltenes contains more aromatic carbon , oxygen - function groups , and less aliphatic chains 但碳黑瀝青質(zhì)與原油瀝青質(zhì)也是不同的,碳黑瀝青質(zhì)的分子結(jié)構(gòu)中含有更多的芳香結(jié)構(gòu)組分和含氧基團,較少的脂肪側(cè)鏈組分。
While haze hovers over other parts of the world , including america and europe , what surprised scientists was just how far the cloud extended , and how much black carbon was in it , according to india ' s national physical laboratory 印度國家物理實驗室稱,如今這片污濁的煙霧已經(jīng)蔓延到了世界其他地區(qū),包括美洲和歐洲,科學(xué)家們對這片褐云能夠覆蓋如此大的范圍深感吃驚,此外,還有煙霧里面的黑色碳的含量之高也是讓人觸目驚心的。
