The beds, rich in organic material from which hydrocarbons originated, are called source beds . 富含能够产生碳氢化合物的有机物质的地层叫做生油层。
The term crude oil is restricted to liquid mixtures of hydrocarbons and related compounds . 原油这个术语是指烃类和与烃类有关的化合物的液态混合物。
Because compounds of this type contain only single bonds they are often referred to as saturated hydrocarbons . 因为这类化合物只含有单键，所以它们常被称为饱和烃。
Cracking involves the chemical breakdown of higher, less volatile hydrocarbons into smaller molecules . 裂化是使较重的低挥发性的碳氢化合物分裂成较小分子的化学分裂。
The hydrocarbon diperchlorate products have utility as detonatable sensitizers for explosives and alkylating agents . 二过氯酸烃基酯产物可用作起爆药的敏化剂及作为烷化剂。
Hydrocarbons may be trapped in anticlines draped over deeply-buried horsts in the pre-deltaic basement . 油气可以被捕集在背斜中，这类背斜盖在前三角洲基底中深埋了的土垒上。

As the name implies, petrochemicals are chemicals made from petroleum, from hydrocarbons found in the latter . 顾名思义，石油化工产品是从石油中，从石油的碳氢化合物中提炼出来的化学制品。
The rate of n0 oxidation also increases proportionately with the square of the hydrocarbon concentration but inversely with the no2 concentration . NO氧化速率与烃浓度的平方成正比增加，而与NO2浓度成反比。
