The surface is darker than originally expected, consisting of a mixture of water and hydrocarbon ice.
表面比原来期待，包括水和碳氢化合物冰的混合物黑暗。Among the most popular are hydrocarbon, GreenEarth and a water-and-detergent method known as wet cleaning.
其中最常用的有碳氢化合物、“绿色地球”以及用水和洗衣粉的湿洗方法。The vast majority of the oil and other hydrocarbons seem to be gone, less than six months after the crude stopped flowing.
在石油和其他碳氢化合物绝大多数似乎消失了，不到半年后的原油停止流动。Over a 40-minute period, the crew on the Transocean oil rig failed to notice the hydrocarbons rising to the surface.
跨海石油公司钻井上的工作人员在40多分钟的时间里未能注意到海面上漂浮的碳氢化合物。The term is often used synonymously with hydrocarbon indicator.
该术语通常用做碳氢指示的同义词。The long-chain hydrocarbons used as diesel fuel do not burn as easily as the lighter ones found in petrol.
用作柴油的碳氢化合物不像汽油中那些较轻的化合物那么容易燃烧。Needless to say that the reservoir beds must remain buried. If exposed to erosion, the petroleum hydrocarbons may be dissipated .
不用说就该明白，储油气层必须始终保持被覆盖埋藏，如果它露出地表遭剥蚀，石油碳氢化合物便会消散。It has also, particularly around the Spratlys, long been believed to be rich in hydrocarbons.
同时，长久以来人们都猜测这一地带蕴含了大量的碳氢化合物，尤其是在环南沙群岛一带。The results indicated that the low temperature, high pressure, and low space velocity are favorable to produce the long-chain hydrocarbons.
结果表明：低温、高压、低空速有利于长链碳氢化合物的生成。
