The World Bank is providing$ 28,000 to the Bo Sign Language Training Center through the Sierra Leone National Social Action Project ( NSAP). 目前,世行正通过塞拉利昂全国社会行动项目向博城手语培训中心提供2.3万美元援助。
The study results show in the injection process, the absorbance and holdup of NsAP in the porous medium are different from that of HPAM since the NsAP solution has special physical network structure. 研究结果表明:在注入过程中,由于NsAP溶液特殊的物理网络结构,使NsAP在孔隙介质中的吸附滞留不同于HPAM;
With self-made sand-filling model to simulate the unconsolidated sand reservoirs with high permeability in offshore oilfields, the feasibility study is conducted for the associated polymer NsAP and the conventional polymer HPAM. 聚合物驱技术能够加快海上油田的采油速度,进而提高采收率。通过采用自制的填砂模型模拟海上油田高渗疏松砂岩油藏,选用缔合型聚合物NsAP和常用的HPAM进行可行性研究。
The NsAP solution has strong shearing resistance in the porous medium because of the action of its intermolecular association. 其分子间的缔合作用,使其在孔隙介质中具有较好的抗剪切性;
