In order to investigate the effects of preform structure on thermal conductivity of needle-punched quartz fiber reinforced epoxy resin composites, the quartz fiber preforms were madeup of layers of non-woven quartz fiber cloth and short-cut quartz fiber web followed by needle-punching step by step, and the composites were prepared by resin transfer molding process.The thermal conductivities of epoxy resin and needle-punched quartz fiber reinforced compositeswere measured by using transient hot-wire methodat room temperature.

生态绿地系统在恢复自然、维护城市生态系统、重塑城市景观以及积极引导城市空间布局方面的重要作用,本文通过反思宁波近三十年的生态绿地规划建设历程,分析问题成因,介绍本次生态绿地系统的规划理念、特征与主要内容,从空间架构、管控政策、建设运营三方面提出应对策略.
散落在城郊偏远地区的古村镇面临保护与发展的困境,以宁波柴桥老镇保护工作为例,通过历史性村镇景观的整体性、动态关联性的研究视角,认识保护、发展的整体关系,探索中国古村镇的保护、发展的路径与对策.规划提出保护与当代居民生活、村镇产业提升、民生基础设施建设积极融合,更好地发挥历史文化价值,为偏远地区的历史村镇带来可持续发展的支撑.
云南的古城旅游开发在近十年来进行得如火如荼,使得云南的各个古城成为各地游人们心目中的旅游胜地,商业化浪潮下的千年古城也面临了各种各样的困惑和挑战.在近些年来,一系列的古城火灾让这些古城再次成了新闻的头条,种种问题发人深省.本文通过重点探求古城火灾一再发生的深层次原因,以独克宗古城灾后重建中消防规划设计专题研究为基础,构建古城消防措施策略,增设古城区的基础设施，完善消防车救灾半径，设置消防控制系统，
政府是住房保障中不可或缺的角色,本文从政府这项公共职能出发,厘清保障性住房政策的发展历程,透析政府在其中的角色转型,有助于明确保障性住房改革的方向,坚定政府所要承担的历史责任,进而实现新常态下“居者有其屋”的人居梦想.探索发现,新中国建立以来,尤其是改革开放以来,中国保障性住房的政策演变过程就是一个渐进的市场化适应性过程.根据保障性住房的保障力度及其主要特征,可以将保障性住房政策大致分为三个阶段:
