1·These reactions increase the probability of incomplete combustion and are more likely to release uncombusted and photochemically active hydrocarbon compounds into the atmosphere.

这些反应增加了不完全燃烧的可能性，更有可能释放未燃尽和光化学活性碳氢化合物到大气中。

2·The grass and paddy emit low-carbon hydrocarbon compounds.

草地和稻田排放甲烷等低碳化合物。

3·The fracture systems of oil field t in Jianghan Basin are evaluated by the method to obtain some basic cognizances of fracture distribution and gaining hydrocarbon compounds in the fracture systems.

并应用该方法对江汉盆地T油田的裂缝组系进行了评价，获得了裂缝可能的分布规律及裂缝组系对捕获烃类的有效性等基本认识。

4·The modern fuel is only allowed tiny quantities of 'non hydrocarbon' compounds, effectively banning the most volatile power-boosting additives.

现代赛车燃油仅允许添加极少量的“非碳水化合物”，这一规则有效地禁止了那些带来急速动力提升的添加剂。

5·Meteorites may have released compounds including hydrocarbon chains and a large amount of ammonia, which is rich in nitrogen.

陨石可能已经释放了化合物，包括碳氢化合物链和大量氨，富含氮。

6·Compounds formed when some or all of the hydrogen atoms in a hydrocarbon (typically an alkane) have been replaced with chlorine and fluorine.

当烃(典型的烷烃)的几个或全部氢被氯和氟取代而生成的化合物。

7·Carbazoles are polar compounds in oils, and they are useful indicators for study of hydrocarbon migration.

咔唑类化合物是原油中极性较大的化合物，是研究油气运移的有效指标。

8·Benzene (1825) Simplest aromatic hydrocarbon (see aromatic compound), parent substance of a large class of chemical compounds.

苯(1825)：最简单的芳香烃，是一大类化合物的母体。

9·The univalent hydrocarbon radical, CH3-, derived from methane and occurring in many important organic compounds.

甲基单价碳氢基，ch3-，由甲烷中衍生出，在许多重要有机化合物中出现。
