随着社会的不断进步发展和乡村振兴战略的落实推进,人们对乡村公共空间品质的要求也在不断提高并趋向多样化,乡村公共空间的更新需求也在不断变化。本研究从空间多义性的视角下找寻乡村公共空间持续性更新的回应,基于朱家林村的发展背景,从居住功能和附属功能、周边环境的作用方式及相互关系出发,分析朱家林村公共空间的发展需求,以空间多义性的模糊性、过程性、关系性设计原则为理论基础,进而提出了边界消隐、弹性预留和功能融合三种更新策略,为当代乡村公共空间可持续更新提供新的理解视角,助力实现乡村公共空间更新,促进乡村建设发展。

Herein,a novel strategy for regulating the phase structure was used to significantly enhance the recoverable energy storage density(Wrec)and the thermal stability via designing the(1-x)[(Bi_(0.5)Na_(0.5))_(0.7)Sr_(0.3)TiO_(3)]-xBiScO_(3)((1-x)BNST-xBS)relaxor ferroelectric *** incorporation of BS into BNST ceramics markedly increases the local micro-structure disorder,causing a high polarization and inhibiting polarization hysteresis for 0.95BNST-0.05BS ceramics,leading to a large Wrec of 5.41 J/cm^(3)with an ideal efficiency(h)of 78.5%.Meanwhile,transmission electron microscope(TEM)results further proved that the nano-domain structure and the tetragonal(P4bm)phase superlattice structure of 0.95BNST-0.05BS ceramics possess an excellent thermal stability(20-200℃).An outstanding Wrec value of 3.18×(1.00±0.03)J/cm^(3)and an h value of 74.500±0.025 are achieved under a temperature range from 20℃to 200℃.This work provides a promising method for phase-structure design that can make it possible to apply temperature-insensitive ceramic dielectrics with a high energy storage density in harsh environments.

对球墨铸铁在不同温度和时间下分别进行渗硼处理,采用金相显微镜观察了渗硼层的形貌,测定了渗硼层的厚度;用显微硬度计测定了渗硼层的表面硬度;用X射线衍射仪分析了渗硼层的物相组成;用扫描电镜测定了渗硼层表面元素含量;并在10%的HCl、H2SO4、HNO3、NaCl、NaOH溶液中做了耐蚀性对比试验。结果表明:渗硼层厚度均匀,呈齿状结构与基体结合牢固,渗硼层主要由Fe2B单相组成;在950℃下保温不同时间,渗硼层的厚度及硬度均随时间的增长而逐渐增大;在不同温度下保温5 h时,渗硼层厚度随温度的升高而逐渐增大,渗硼层的硬度随温度的升高先增大后减小,除HNO3外,渗硼处理后试样的耐蚀性均比未渗硼的试样的耐蚀性能好。
