| 1. | Hydrocarbons are among the most important organic compounds .
烃是一类最重要的有机化合物。 |
| 2. | The exact mechanism of dealkylation has not been established .
脱烃作用的确切机制还没有确定。 |
| 3. | During incomplete combustion some of the hydrocarbon fuel is cracked .
在不完全的燃烧中，一些烃燃料裂解。 |
| 4. | The relatively volatile liquid hydrocaroons, is called gas condensates .
较易挥发的液态烃，又称气体凝析液。 |
| 5. | These compounds range from hydrocarbons through various oxidation products .
这些化合物从烃类到多种氧化物。 |
| 6. | With this restricted frequency range it is not applicable to hydrocarbons .
这个较紧缩的频率范围不适用于烃类。 |
| 7. | This may well hold good for any limited series of related hydrocarbons .
这种关系在一些有关烃类的有限系列中可能适用。 |
| 8. | The benzenoid hydrocarbon are all nonclassical and, thus potentially aromatic .
苯环型烃都是非经典烃，因此，可能是芳香烃。 |
| 9. | Not all accumulations of hydrocarbons are necessarily the result of hydrodynamics .
并不是所有烃类的储集都必然是水动力的结果。 |
| 10. | Hydrocarbous are thus trapped and cannot escape either updip or vertically .
因此烃类被圈闭，无论在上倾方向或垂直方向都不能散失。 |
