The development of the forecast models shows that the foreign forecast models evolved from monocyclic ones to multi-cyclic ones emphasized the models'vertical development,whereas Chinese models such as the Weng's model and many others emphasized their horizontal development.

摘要追溯了石油峰值理论的起源，对国内外一系列关于石油峰值理论模型的定量研究表明，石油峰值理论模型大体有3种类型：①基于生命有限体系的生命模型；②基于概率论和统计学理论的随机模型；③基于生产实践和理论推理的广义数学模型。

Everything, offshore, Alaska, shale, nonconventional, coal to liquid, gas to liquid, and nuclear.

在各个领域挖掘潜力，包括在近海的石油开采，在阿拉斯加、以及从岩油中提炼石油，甚至把煤炭和天然气以及核能都通过市场运作（鼓励这些产品的使用以节约石油产品）转化为油品。

Many oil analysts expected the 24 pct stake awarded to the French oil major to go to one of its Norwegian counterparts, either Norsk Hydro or Statoil.

大多数石油分析家预计，授予法国石油公司24%的股份，将会落到一家挪威公司手中，或者是挪威水电公司，或者是挪威国家石油公司。

All 13 of the oil firms that outshadow it are national oil companies: partially or wholly state-owned firms through which governments retain the profits from oil production.

名列在前的所有13家石油企业都是国家石油公司，它们由国家部分或是全部所有，政府从中获取石油生产的利润。

Identification of PAHs sources suggests that all up-cores were dominated by petrogenic sources, but all down-cores except for S17 and S18 were dominated by pyrogenic sources or mixed sources. In contrast, biogenic sources were found dominant in S17 and S18 as they were characterized by higher ratio of perylene/Σpenta-PAHs.

各岩心表层皆大致倾向石油来源，随著深度的增加而逐渐倾向石油燃烧来源或石油/燃烧之混合性来源，其中位处峡谷南隅之岩心S17及S18则有较明显之生物性来源贡献。

In this the moment of truth, must increase the strength that introduces foreign capital and advanced science and technology, the development of industry of stimulative China oil; All-around, diversity ground is developed and use international oil market, develop pair of petrolic in order to ensure economy continuously demand.

在此要害时刻，须加大引进外资和先进科技的力度，促进中国石油工业的发展；全方位、多元化地开拓和利用国际石油市场，以保障经济持续发展对石油的需求。

So piperylene petroleum resin was applied preferably in downstream products,and the products yield was increased by improving post treatment process.

介绍了国内外间戊二烯石油树脂合成技术的改进进展，主要体现在催化体系的改进及聚合单体和溶剂的改变，通过引入官能团及共混等方法改善间戊二烯石油树脂的色度、耐候性和相容性等性能，从而使间戊二烯石油树脂在下游产品中得到更好地应用；通过后处理精制工艺的改进，可提高产品的收率。

Petroleum is an unreproductive strategic resource, because it is pockety and finite, to gain and control sufficient petroleum becomes one of the main aims of big countrys secure tactic.

石油是一种不可再生的战略资源，由于世界石油资源分布不均、数量有限，因此，获得和控制足够的石油资源便成为大国安全战略的重要目标之一。

The our company after relates in every way according to the above situation, already from overseas massively purchased the ZX-10 series desulphurization catalyst, has been able to coke with this catalyst technology the sulphonium compounds which the triphenyl contained, the nitrogen compound , the unsaturated compound and very many impurities, the fetid odor and so on removes, after the processing triphenyl always Sulfur content was lower than the petroleum benzene, the smell, the color, was consistent with the petroleum benzene.

目前焦化三苯在工业上使用范围小，销售价格也低于石油三苯。其主要原因是硫、噻吩等杂质含量高、气味重。而现在国际、国内焦化三苯、汽油、柴油等产品脱硫提纯去杂质的工艺均采用高压催化加氢法处理，该工艺设备投资巨大。根据以上情况我公司经多方联系，现已从国外大量购进ZX-10系列脱硫催化剂，用本催化剂技术已能将焦化三苯所含的硫化合物、氮化合物、不饱和化合物及很多杂质，臭味等脱除，处理后的三苯总硫含量低于石油苯，气味、颜色，均与石油苯一致。

There are obvious syntrophic effets between marine OHCBs Alcanivorax and Marinobacter strains in the oil biodegradation process, which could not only accelerate the oil biodegradation, but also decompose thoroughly the more ecotoxic high molecular weight compounds in crude oil.

在石油降解过程中海洋专性解烃菌之间存在明显的协同效应，不仅可以加快石油降解，还可以彻底降解石油中生态毒性较大的高分子量化合物。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
