天然气

Therefore, the gas pipeline system must be under operation with the condition higher than the hydrocarbon dewpoint of the pipeline gas.

因此，要求天然气输配系统必须保证在高于管输天然气烃露点的条件下运行。

Herein this paper discusses on two testing methods: cooler surface condensation hygrometer and gas chromatography, the latter of which is thought to be more popular in the world. It is also pointed out that the index of hydrocarbon dewpoint depends only upon the operation conditions and environment of pipelines and can not be specified until a suitable method for determination is established.

为此，讨论了测定商品天然气烃露点的两种方法--冷却镜面法和气相色谱法，认为后者才是当前发展的方向；并指出商品天然气烃露点指标仅取决于管道的操作条件及运行环境，且只有建立了准确的测定方法后才有可能确定。

Seismic sections show the occurrences of diapirs and gas filled zones that are communicated with seafloor through faults.

地震剖面显示盆地内发育有泥底辟和气烟囱、沟通泥底辟和气烟囱与海底的断裂及可能正在活动的天然气冷泉，这些特征非常有利于天然气水合物的发育。

The occurrences of diapirs, gas-filled zones and gas plumes in seawater in Qiongdongnan Basin of South China Sea indicate that there may exist seepage system gas-hydrate reservoirs.

南海琼东南盆地发现的高压泥底辟构造、海底&气烟囱&和天然气冷泉表明该地区可能存在着渗漏系统天然气水合物藏。

Based on the fundament of analyses of abroad and our country CNG engine technology, the developing strategy of CNG engine has suggested. Based on the EQD180-20 diesel which the basic construction unchanged, the necessary modified designing for CNG engine was made which included combustion system, intake and exhaust system, cylinder head, piston, and turbocharger.

在分析国内外天然气发动机技术的基础上，提出了满足国3排放的电控喷射单燃料CNG发动机开发方案；以EQD180-20柴油机为基础机型，在基本不改变原机结构的前提下，对燃烧系统、进排气系统、气缸盖、活塞和增压中冷系统进行相应的变型设计；采用稀薄燃烧、增压中冷、低涡流燃烧系统、电控分组点火、开环控制、电控CNG喷射系统和氧化型催化器等技术，降低排放，保持天然气发动机的动力性和经济性。

On the basis of a la rge number of previous research,geochemical characteristics and in dexes of mixed origin natural gases f rom Ordovician weathered crust gas r eservoirs in Central Gas Field in the Ordos Basin are systematically studied.

在前人大量研究的基础上，系统研究了该气田天然气混源的地球化学特征与标志，并利用多指标综合评价了气藏的气源。研究结果表明，鄂尔多斯盆地中部气田奥陶系风化壳天然气具有高—过成熟干气的组分和同位素特征。

In December Mr Hu and the leaders of three Central Asian countries gathered at the Saman-Depe gasfield in eastern Turkmenistan for a moment of crowning symbolism. The four men turned a tap to inaugurate a 1,833km (1,139-mile) gas pipeline, running through Uzbekistan and Kazakhstan into China's far-western region of Xinjiang.

2009年12月，在位于土库曼斯坦东部的萨满德普天然气田(Saman-Depe gasfield)，胡锦涛与中亚三国的领导人聚会，四位领导人举行了象征性的仪式，共同开启了长达1833公里（1139英里）的天然气管道阀门，这条天然气管道将穿越乌兹别克斯坦和塔吉克斯坦，到达位于中国西部的新疆。

Gas vapor reforming is the traditional techniq ue of synthesis gas producing,which can make the chemicals such as hydrogen,methan ol,dimethyl ether,etc.,also which is the core technology of the battery with gas methanol fuel.

天然气蒸气重整是传统的合成气制造技术，可以用来制造氢气、甲醇、二甲醚等化工产品，也是天然气制甲醇燃料电池的核心技术部分。

The pipeline, known as south stream, will carry gas under the black sea from Russia to Europe.

South Stream天然气管道将通过黑海，将俄罗斯的天然气运往欧洲。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
