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，我们还对py一gc一ms分析时产生的含碳残余物进行了结构表征，表明它具有高度芳香性的结构，十分稳定。
The kinetics of organic matter generating hydrocarbon which based on the composition and structure of kerogen and chemical kinetics . from the point of view of chemistry , the calculating quantity of hydrocarbon is scientific , exact and actual 有机质成烃动力学是定量评价烃源岩生烃潜力的重要研究方法之一，它是建立在干酪根的组成结构和化学反应动力学基础之上的。
Organic chemistry is involved both in the analysis of oil and gas and in the study of the diagenesis of the plant and animal tissues in sediments and the way in which the resultant organic compound , kerogen , generates petroleum 有机化学则可应用于分析原油和天然气，研究沉积物中植物和动物组织的成岩作用，研究动植物组织转化为合成有机化合物，揭示由此而生成的有机化合物干酪根生成石油的方式。
The results of these work indicated that som in top soils and sediments are highly heterogeneous and conprise a wide range complex organic matter such as humic acid , kerogen , and black carbon , and som have a nice bit of black carbon 综上所述，表层土壤和沉积物中的有机质是高度非均质的，包括腐殖酸、干酪根和碳黑，并且碳黑具有相当高的含量。碳黑在来源、性质和结构上不同于腐殖酸和干酪根，它是生物体和化石燃料不完全燃烧产生，具有更加稳定的性质和结构。
4 . based on the research of geochemical characters of hydrocarbon source rock and comparison of oil and gas sources , it is indicated that the condensed oil and gas in buried hills mainly came from es3 effective hydrocarbon source rock of type iii kerogen - type ii2 kerogen in banqiao deprssion and qikou depression beside both sides of the tilting horst , and which is the main source of buried hill with early reservoir and late oil and gas source 4根据烃源岩地球化学特征和油气源对比，指出潜山凝析油气主要来自翘倾地垒块两侧板桥和歧口凹陷的沙三段腐植-偏腐植型有效烃源岩，该凝析油气是“新生古储”型潜山的主要油气源。
The soils and sediments organic matter ( som ) are highly heterogeneous and comprise various complex organic macromolecules such as humus , kerogen , black carbon ( bc ) , etc . the relative abundance , characteristics and structure of these som play a important role on the global carbon cycles , global change , transformation and fate of the organic and inorganic pollutants , the soil fertility 土壤和沉积物有机质是高度非均质的，包括许多复杂的有机高分子聚合物如腐殖质、干酪根、碳黑等。这些有机质的相对含量，性质和结构对全球碳循环，全球气候变化，有机和无机污染物在自然界的迁移、转化和归宿，土壤的肥力等有非常重要的影响。
The analysis of 13c nmr and py - gc - ms also show each fraction of som has it ' s structural characterization . the aromatic carbon conte nt increasing and carbohydrate , oxygen - function groups decreasing from humic acid , kerogen to black carbon , molecular structure became more condensed , rigid , and stable . 2 ~ ( 13 ) c核磁共振分析也说明了腐殖酸、干酪根和碳黑具有不同的结构特征，从腐殖酸、干酪根到碳黑，芳香碳结构增加，含氧官能团、碳水化合物等结构减少，整个大分子结构更加致密、刚硬和稳定。
Humic acid usually formed from phytoplanktons , zooplanktons , and epicontinental vascular plants through biodegraded and condensated reaction . krogen derived either from humic acid or from the reworking materials . differing from humic acid and kerogen , bc was produced from the incomplete combustion of fossil fuels and biomass 并且不同的有机质有不同的来源，腐殖酸通常是浮游生物和陆生的高等植物经过生物降解、聚合等过程形成的；干酪根是腐殖酸进一步演化而成，既有原生的也有异地迁移而来的；碳黑则不同于腐殖酸和干酪根，它是生物质和煤、油等化石燃料经过燃烧产生的。
According to the chemical experimental data of residual organic carbon content , kerogen carbon isotope , aliphaltic gas chromatography mass spectrometry of 67 outcrop specimens in the baise basin , the authors analyse the geochemical characteristics of the type and the maturation of organic matter in the lower triassic - devonian source rock 根据百色盆地周缘大量露头样品的残余有机碳含量、干酪根碳同位素、饱和烃色谱及色质等地球化学实验数据，分析了下三叠统泥盆系海相烃源岩的有机质丰度、类型、热演化程度。
In the whole city the proven mineral reserves are of 53 kinds , of which the kerogen shale is 5 . 1 billion tons , kaolin over 0 . 3 billion tons , ranking first in the country . rare earth and porphyrite tin are big mines on the country scale ; xinyi jade mine , reputed as " jade of the south " is one of the three big jade mines in the country 全市已查明矿藏53种，其中油母页岩51亿吨，高岭土储量3亿多吨，均居全国首位；稀土、斑岩型锡矿属全国大矿；被誉为“南方璧玉”的信宜玉石矿是全国三大玉石矿之一。
