| 1 | 政府如何支持公私合营模式发展——20个欧洲国家PPP的政府支持情况评估比较显示文摘本文从制度的视角构建一个政府支持公私合营模式(Public Private Partnership,PPP)程度的指数——PPP政府支持指数(PPP Governmental Support Index,GSI)——以评估政府规定的制度体系对在交通基础设施和其他行业引入和推广PPP具有何种程度的促进或阻碍作用。首先,基于大量文献综述界定PPP政府支持指数的要素,包括关于PPP的政策和政治承诺、法律和监管框架,以及精心设计的PPP支持安排。其次,计算20个欧洲国家的PPP政府支持指数,将其分类并比较各国政府对基础设施领域PPP支持程度的异同。再次,探讨20个欧洲国家的制度指数得分与基础设施领域PPP行为的潜在联系。最后,讨论当前的PPP政府支持指数的潜力、实用性以及方法局限性,并详细阐述如何将该指数用于加强交通或其他领域PPP的比较研究中。 | Koen Verhoest Ole Helby Petersen Walter Scherrer Raden Murwantara Soecipto 张帆 | 2015 | 城市交通2015,13,4: | 13 |
| 2 | Visualization and quantification of water movement in porous cement-based materials by real time thermal neutron radiography:Theoretical analysis and experimental study显示文摘Water movement in porous cement-based materials is of great importance when studying their deterioration processes and durability.Many traditional methods based on mass changes,electricity or nuclear magnetic resonances are available for studying water transport in cement-based materials.In this research,an advanced technique i.e.thermal neutron radiography was utilized to achieve visualization and quantification of time dependent water movement including water penetration and moisture vapor in porous cement-based materials through theoretical analysis and experimental study.Because thermal neutrons ex-perience a strong attenuation by hydrogen,neutron radiography exhibits high sensitivity to small amounts of water.A neutron transmission analysis for quantitative evaluation of raw radiographic measurements was developed and optimized based on point scattered functions(PScF).The determinations of the real time and space dependent water penetration into uncracked and cracked mortar samples,as well as the drying process have been presented in this paper.It is illustrated that thermal neutron radiography can be a useful research tool for visualization and quantification of water movement in porous building materials.The obtained results will help us to better understand deteriorating processes of cement-based materials and to find ways to improve their durability. | ZHANG Peng1,WITTMANN F H1,2,ZHAO TieJun1,LEHMANN E3 & JIN ZuQuan1 1 Center for Durability & Sustainability Studies of Shandong Province,Qingdao Technological University,Qingdao 266033,China 2 Aedificat Institute Freiburg,Freiburg D-79100,Germany 3 Department of Spallation Neutron Source(ASQ),Paul Scherrer Institute,Villigen PSI CH-5232,Switzerland | 2010 | Science China(Technological Sciences)2010,53,5: | 6 |
