【摘要】 <正> 在生油研究中,人们往往根据生油岩抽提物中烷烃的色谱分析资料作出成烃先驱物质,即生源构成的定性判断。一般来说,是把正构烷烃 C₂₁以下的化合物作为起源于脂肪酸的成分,而把 C₂₂以上的化合物作为起源于生物蜡的成分。在这方面,现代生物体中脂肪酸的分布特征以及 Lijmbach 的模拟实验结果等,为这种生源构成分析方法提供了更多还原

【Abstract】 The analytic principles and prerequisites for structure of the biogenetic substanceof dissemninated hydrocarbones in source rocks by gas chromatograms are discussedhere by the authors,and these hydrocarbones have been classified into four peakgroups derived from fatty acids,biological waxes,pigments and other biologicallipids.In addition,elucidations of some characters of their evolution are putforward in conjunction with computing an example.更多还原
