析共有产权住房政策的公平价值——以江苏淮安经验为例

住房市场化的推进,使我国商品房产权日益清晰,从而减少了政府在住房管理上的职责,同时也使政府在公共住房分配中遇到更多问题。政府作为社会价值的分配主体,在有限的住房供给下,如何通过产权配给、申请登记和轮候排队系统,使被排除在市场之外的中低收入群体的住房需求得到公平的对待,关涉到住房分配政策的公平价值,也是对政府公信力的考验。江苏淮安市首创的共有产权住房政策从住房供给、住房分配等层面定位了政府在住房市场上的管理角色,强调了公平价值在政策制定中的地位,为我国未来住房政策的创新提供了参考

Extraordinary strain hardening by gradient structure

Gradient structures have evolved over millions of years through natural selection and optimization in many biological systems such as bones and plant stems, where the structures change gradually from the surface to interior. The advantage of gradient structures is their maximization of physical and mechanical performance while minimizing material cost. Here we report that the gradient structure in engineering materials such as metals renders a unique extra strain hardening, which leads to high ductility. The grain-size gradient under uniaxial tension induces a macroscopic strain gradient and converts the applied uniaxial stress to multiaxial stresses due to the evolution of incompatible deformation along the gradient depth. Thereby the accumulation and interaction of dislocations are promoted, resulting in an extra strain hardening and an obvious strain hardening rate up-turn. Such extraordinary strain hardening, which is inherent to gradient structures and does not exist in homogeneous materials, provides a hitherto unknown strategy to develop strong and ductile materials by architecting heterogeneous nanostructures.</p

焙烧温度对甲硫醇催化剂K_2WO_4/Al_2O_3结构和性能的影响

研究了焙烧温度对溶胶-凝胶法制备的甲硫醇催化剂K2WO4/Al2O3的表面结构和催化性能的影响.表征结果显示,K2WO4在Al2O3上分散得较好,在450和550oC焙烧的催化剂颗粒大小均匀,无明显团聚现象.随着焙烧温度的升高,催化剂的比表面积减小,表面钨物种与Al2O3的相互作用减弱,与碱物种的相互作用增强,酸碱强度降低.K2WO4/Al2O3表面不含质子酸.催化剂活性与其比表面积及表面的共轭酸碱对密切相关.评价结果表明,在550oC焙烧而制得的催化剂活性最高

No Brönsted acid was found on the catalyst surface. The catalytic activity of the catalyst is closely related with the specific surface area and the presence of conjugate acid-base pairs on the surface. Activity assay results show that the catalyst calcined at 550 oC exhibits the highest activity for the reaction.重庆紫光化工股份有限公司的经费资
