The bulk of these upward revisions occurs in North America and reflects increased demand for liquids, LPG and ethane, due to heating and industrial use and increased petrochemical demand. Baseline 2001 revisions due to resubmissions of annual data from OECD Member countries carry forward into succeeding periods, raising 2003 and 2004 demand accordingly.

需求量上调的地区主要是北美，原因是取暖用油和工业用油以及石化工业对于液化天然气、液化石油气以及乙烷的需求都上调了。2001需求数据修正的另一部分原因是经合组织成员国修正了各自国内的年度数据，我们也据此相应提高了2003年和2004年的数据。

A persistent organochlorine insecticide, also known as dichlorodiphenyltrichloroethane, that was introduced in the 1940s and used widely because of its persistence (meaning repeated applications were unnecessary), its low toxicity to mammals and its simplicity and cheapness of manufacture.

中文解释=难以分解的有机氯杀虫剂，化学名称为二氯二苯基三氯乙烷，因其在环境中的持久性、对哺乳动物的低毒性和制造容易、花费低，所以在1940年代被大量使用。

On condition that the critical temperature and critical density or critical specific volume are known, the density of saturated liquid can be calculated with high accuracy.

利用该方法在已知临界温度和临界比容或临界密度的条件下，可以对所有乙烷系氟里昂的饱和液体密度进行推算，该方法推算的平均偏差不超过1%，最大偏差不超过1.5%，可满足CFCs替代物研究和应用的需要。

The flame retardant asphalts were prepared with Liaohe AH-70 type high-quality paving asphalt as feedstock,decabromo-diphenyl oxide,decabromo-diphenyl ethane,antimonous oxide et al as flame retardants,aluminum hydroxide as smoke inhibitor and drawing off oil high in aromatics as dispersion medium under the condition of heating and mixing.

以辽河AH-70高等级道路沥青为原料，十溴联苯醚、十溴联苯乙烷、三氧化二锑等为阻燃剂，氢氧化铝为抑烟剂，富含芳烃的抽出油为调和剂，在加热搅拌的条件下，制得了阻燃沥青。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.
