摘要
用二氯甲烷抽提宁强碳质球粒陨石中的可溶有机质,经色谱、色-质谱分析鉴定后,发现有正构烷烃、异构烷烃、烯烃、萘、甲基蒽、甲基萘等有机化合物。采用实验室内防止人为污染、空白试验对照和多次分析等方法,证实这些化合物并非室内污染所致,应是陨石自身存在的有机物质。此外,讨论了这些有机质的可能成因及其意义。
Hydrocarbons in the Ningqiang meteorite were extracted with methylene chloride and analyzed by GC and GC-MS. As a result, n-alkanes, isoalkanes, alkenes, naphthalene, methyl-naphthalene, methyl-anthra, etc. have been recognized in the extract. By the contamination-preventing procedure and comparison with blank and repeated examinations, it has been demonstrated that the organic matter in the Ningqiang meteorite seems to be indigenous and has not been contaminated in the laboratory. In addition, the origin of organic matter in the meteorite and its significance are also discussed.
