中文摘要：

在 20082009，热水的藤壶和沉积样品在中国海洋矿物质资源 R&D 协会(COMRA ) 的调查期间从西南印度理兹被收集。样品被煤气的层析团分光计(GCMS ) 分析，揭示是丰满的酸和 alkylbenzenes 的热水的藤壶和沉积的主要器官的成分。拥有了明显的甚至碳优点的 N 链烷也在热水的沉积被检测。芳香的混合物的高集中可能是 macromolecular 的结果热改变。在海底的热水的生态系统的微生物，特别那些与硫新陈代谢有关，丰满的酸的高集中的来源可能在这些样品被检测。在高度，温度和高度迫使热水的环境，拥有了明显的甚至碳优点的 n 链烷可能从羧基的酸和另外的类脂化合物混合物的热改变发源。

英文摘要：

In 2008-2009, hydrothermal barnacle and sediment samples were collected from the Southwest Indian Ridge during a survey of the China Ocean Mineral Resources R＆D Association （COMRA）. Samples were ana- lyzed by gas chromatography-mass spectrometer （GC-MS）, revealing the main organic constituents of hy- drothermal barnacle and sediment to be fatty acids and alkylbenzenes. N-alkanes which possessed obvious even carbon advantage were also detected in hydrothermal sediment. The high concentrations of aromatic compounds might be the result of macromolecular thermal alteration. Microorganism in the submarine hydrothermal ecosystem, especially those related to sulfur metabolism, might be the source of the high con- centrations of fatty acids detected in these samples. In high temperature and high pressure hydrothermal environments, n-alkanes which possessed obvious even carbon advantage might originate from thermal alteration of carboxylic acids and other lipid compounds.
