CO2 for the compressors lubrification in particular polyolester (POE oil and polyalkylglycol oils there are still uncertainties in the definition of an optimized oil in relation to the various applications.

二氧化碳的压缩机润滑（特别是polyolester功能的石油和polyalkylglycol所油）仍然存在着不确定性的定义，一个优化的石油有关的各种应用。

The OECD estimates in its latest Economic Outsee those, if oil prices averaged $22 a barrel for a full age, compare notd with $13 in 1998, the will increase the oil import bill in rich economies by only 0.25---0.5% of GDP.

OECD在其最近的《经济瞭望》中估计，假如石油价格与1998年的每桶13英镑相比在一年中平均为每22英镑，这也只会给富裕的经济体的石油进口账单上渐增GDP的0.25％到0.5％。

With the development of oil drilling and the increase of the deep ocean drilling,the requirements of drilling additives were also promoted to satisfy the high temperature resistance and salt resistance.2-Acrylamido-2-methylpropane sulphonic acid is an acrylamid derivatives with -SO3H and -CH2=CH2- in its molecular structure.

随着世界能源需求的增加和钻探技术的发展，向地层深部挺进，向深地层要油气已成必然。在我国，这种现象尤为明显，作为全国石油天然气产量的主力接替区的西部，其石油资源量的73%、天然气资源量的52%都埋藏在深地层。

In other words, the global recession has only interrupted the "supercycle" of which many analysts used to speak, during which the normal boom-and-bust cycle of oil and other commodities would give way to a protracted period of high prices, as ever-growing demand from emerging markets swallowed everything the extractive industries could produce.

然而，石油工业是短期的设备和人力，由于几十年来投资不足，在80年代和90年代，当时的价格也很低。这让努力扩大尽管强大的价格信号，最近几年，因此，很难抽身，以满足世界发展中巨大的新市场，包括中国和印度的石油消耗量已快速增长。

The allelopathic bioactivities on mycelial growth and the dose-activity relationships of two different Eucalyptus globulus leaves extracts,petroleum ether extract and chloroform extract,against five phytopathogens,Pyricularia oryzae,Rhizoctonia solani,Fusarium solani,Venturia pyrina,and Alternaria solani,were determined by mycelial growth rate method in PDA petri dish.

采用菌丝生长速率法，在PDA培养基上测定了蓝桉叶片的石油醚和氯仿提取物对水稻稻瘟病、小麦纹枯病、蚕豆根腐病、梨黑星病、番茄早疫病5种植物病原菌的化感作用，研究了蓝桉叶片的石油醚和氯仿提取物与病原菌的剂-效关系和提取物对病原菌菌丝生长速率的影响。

It is a grotesque and somehow morbid picture to drive by these areas, where everything just seems to be black, where dead trees are sad indicators of the once flouring landscape, where rusty oil rigs, pipelines, and. whole factory plants are remnants of the once blooming Soviet petrochemical industry.

开车经过这些像是一张怪异病态的照片的地区，每一样东西都是黑黑的，枯树是洒落在这片风景里令人难过的指标，生锈的石油装备、管道、以及整个工厂都是曾经发展苏联石油化学工业的残余。

The internal documents obtained by Dow Jones Newswires cataloged several instances in the past three years in which companies misreported the amount of oil they had in storage, sometimes by over two million barrels in each weekly survey over the course of a year, a significant error considering that amount can account for the entire change in inventories from week to week.

道琼斯通讯社获取的这些内部文件显示，过去三年曾发生多次企业误报其石油储量的情况，有时候是整整一年里的每次调查中都误报200多万桶。200万桶可以相当于石油库存一周的整体变动量，所以这个差错是非常大的。

The Nebraska-based investor known as the Sage of Omaha saw his fortune swell by $10bn (￡5bn) to $62bn last year as he made a series of shrewd punts , including a bet on Brazil's currency and profit on the oil company PetroChina, which has drawn flak for its links to Sudan's government.

这位居住在內布拉斯加州的投资家被尊称为奥马哈的先知（Sage of Omaha。去年，通过一系列精明的投资，他的个人财富猛增了100亿达到620亿美元。这些投资包括成功判断巴西货币的走势以及投资中国石油获利。中国石油因为与苏丹政府的牵连而备受批评。

Self-elevating drilling platforms play an important role in the reconnoitering and the exploitation of offshore oil fields. But with the advancement of offshore oil industry, the earlier self-elevating drilling platform cant function well to satisfy the demands of the development of offshore oil reconnoitering and exploitation. They should be upgraded to be able to function as well as possible.

自升式钻井平台在海洋石油勘探开发中发挥着积极的作用，但随着海洋石油工业的发展及海洋勘探技术的不断提高，早期设计建造的自升式钻井平台在许多方面不能适应形势发展的需要，需要进行升级改造，以提高施工能力。

Certainly, the roller-coaster ride of oil prices over the last couple of years, as oil markets and financial markets have become more integrated, has made volatility a central preoccupation for policymakers who do not want to see their economies whipsawed by huge price swings.

当然，随着石油市场和金融市场之间的联系日益紧密，过去几年来有如过山车一般上蹿下跳的油价已使得石油成为了政策制定者们脑中的头等大事，他们谁都不想让自己国家的经济因为巨大的价格波动而遭受双重打击。
