The light oils originated from high mature rocks . in the process from source to trap with gas washing and evaporative fractionation , the oils got rich in aromatic compounds and poor in other compounds , which indicates that gas washing has great effects on the oil compositions 認為這些輕質油來自高成熟的烴源巖,在其運移過程中受到氣洗,發生蒸發分餾作用,使得其輕組分中芳烴化合物苯和甲苯相對富集,而其它組分則大量損失,表明了氣洗對油的改造是十分強烈的。

Fouriertransformation infro - red microspectroscopy micro - ftir technique was used to investigate the chemical compositions and structures of cutinite , vitrinite and fusinite from jurassic coals in tarim basin at different temperatures . the results show that the chemical structure of cutinite is mainly composed of long aliphatic - side chain with minor amounts of aromatic compounds . vitrinite is mostly composed of aromatic compounds , in addition to large amount of short aliphatic - side chain compounds . whereas fusinite are dominant by aromatic structure . the study indicates that cutinite is one of the best oil source - rocks , with the higher hydrocarbon - generation potential ; vitrinite is one of better gas source - rocks , and has medium hydrocarbon - generating potential ; fusinite has little hydrocarbon - generating potential . in addition , the components of aliphatic structures of cutinite , vitrinite and fusinite decrease , the aromatics are enriched and condensation of aromatic structure increases with increasing the temperature , and along with the rise of temperatures , the intensity of aliphatic structure and heteroatomic compounds decrease obviously , however the aromatic structure changes a little 應用顯微紅外光譜技術,對塔里木盆地侏羅紀煤中有代表性的3種組分角質體鏡質體絲質體在不同熱模擬溫度下的結構組成變化特征進行了研究,結果表明:角質體結構組成中含有較豐富的長鏈脂族結構,而芳香結構和含氧官能團的含量則相對較少與此相反,絲質體結構組成中芳香烴占絕對優勢,而脂族結構含量則很少鏡質體結構組成介于角質體和絲質體之間,含有較多的短鏈脂族結構和芳香結構。

In the treatment of wastewater containing aromatic compounds using the supercritical water oxidation method , the removal rate increases with the increase of temperature , pressure , and retention time 超臨界水氧化法處理含芳香族有機廢水,隨反應溫度和壓力的升高及停留時間的延長,苯酚去除率提高,在很短的停留時間內,苯酚的去除率可達96 %以上。

On the base of wen wu , i programmed the software by using of vb and the animated cartoon tool - 3d . after finishing the software , i did the validated experiments using 8 aromatic compounds as sample 在完成軟件的研究開發工作后,以8種芳香類化合物為樣品,進行該程序的實驗驗證。

Aromatic compounds in river nearby the certain chemical factory were determined by a purge and trap method in combination with gas chromatography mass spectrometry 摘要利用吹掃捕集氣相色譜質譜聯用技術,對化工廠附近有可能受污染的地表水進行了定性和定量分析。

Producer of pesticide , dye , and pharmaceutical intermediates , with an emphasis in phosphorus chemicals . also offers phenyl methyl pyrazolone and several other aromatic compounds -主要生產染料農藥醫藥中間體,產品有氨基胍碳酸鹽,氨基胍重碳酸鹽氨基胍碳酸氫鹽。

His group has found hundreds of genes that encode enzymes which produce flavourings and aromatic compounds 他的團隊還揭秘了幾百種酶的基因,正是這些酶的基因控制了造成濃郁口味和芬芳氣味的化合物。

They found that it was composed of various aromatic compounds and sulfides in addition to large quantities of carbon 原來它的組成除了大量的碳,還有各類芳香族化合物和硫化物。
