Supercritical fluid extraction and fractionation ( sfef ) are used to separate daqing and liaohe decanted oils into a number of narrow fractions 摘要以大庆和辽河油浆为研究对象，采用超临界流体萃取分馏技术将其切割成窄馏分，分析了油浆窄馏分的性质及组成随收率变化的规律。
As the cumulative yield reaches 70 % for daqing decanted oil or 25 % for liaohe feed , the content of aromatics exceeds that of saturates and goes up rapidly while the saturates drop down by the same level 大庆、辽河油浆分别在累积萃取收率达70 %和25 %后，窄馏分中的芳香分含量超过饱和分且迅速增加，而饱和分含量相应下降。
The territory development department is conducting feasibility studies of several major reclamation projects to provide new land for growth , to decant existing population and to provide or upgrade facilities to enable the redevelopment of old and run - down areas 拓展署现正就数项大型填海计划进行可行性研究，以提供发展用地，调迁目前人口，并为旧区和失修地区重建工作提供或改善设施。
Abstract : the authers has studied the phase cha racteristics and phase equilibri um of sda ( solvent - deasphalting ) of dagang residue - ic4 and dagang residue m ixed w ith some ccdo ( catalytic cracking decant oil ) - ic4 system under subcritical condit ions systematically 文摘:系统地研究了大港渣油-异丁烷体系及混有催化裂化澄清油的大港渣油-异丁烷体系在亚临界条件下，溶剂脱沥青过程的相特性及相平衡。
The territory development department ( tdd ) is conducting detailed design of several major reclamation projects to provide new land for growth , to decant existing population and to provide or upgrade facilities to allow for the redevelopment of old and run - down areas 拓展署现正就数项大型填海计划进行详细设计工作，目标是提供发展用地和调迁现有人口，并提供或改善设施，方便重建旧区和失修地区。

That the government further pledges to support , in principle , the added administrative cost incurred during the transition ( as front - end loading for a new university ) and the capital spending needed to build extra teaching and office space for decanting of departments and programmes , with the level of such support to be negotiated 政府原则上也要答应承担大学在过渡期间的额外行政开支(作为成立新大学的前期投入) ，也要负责斥资兴建新教学楼及办公室，以应付学系和部门搬迁时的需要。政府应与大学磋商此类支出的资助额。
