Thermal properties of hierarchical YSZ and LZO ceramic microspheres with multi-scaled voids investigated by using theoretical,experimental and simulation methods

Heat transfer within ceramic feedstock powders is still unclear, which impedes optimization of the thermal and mechanical properties of the thermal sprayed coatings. The microspheres (yttria-stabilized zirconia YSZ and lanthanum zirconate LZO) were prepared via the electro-spraying assisted phase inversion method (ESP). The thermal properties of the two ESP microspheres and a commercial hollow spherical powder (HOSP) were investigated by using theoretical, experimental, and simulation methods. Thermal conductivity of the single microsphere was estimated via a novel nest model that was derived from the Maxwell-Eucken 1 and the EMT model. Thermal conductivity of a single YSZ/LZO-ESP microsphere prepared at 1100–1200 °C was within 0.36–0.75 W/m K, which was ～ 20 % lower than that of a single YSZ-HOSP microsphere with a similar porosity. Heat flux simulation showed that high tortuosity around the multi-scaled voids of the ESP microsphere led to a more efficient decrease in thermal conductivity compared with total porosity.

从民居建筑布局看“堂文化”的神圣表述——“堂文化”所呈现的中国文化思维模式论之一

民居里的堂屋是民居建筑里的“神圣空间”,在我们阅读这种神圣空间的同时,我们不仅能够读出中国文化的核心思想观念,而且可以读出中国文化里的思维模式,以及中国文化的结构体系。而这些与中国民居建筑手法融合,使得民居的“堂”成为中国文化中典型的神圣“话语”符号。

明式家具的审美特征与现代中式家具设计

简单分析了“天人合一”和“阴阳五行”的哲学观对中国古代设计的影响;进而总结了明式家具的审美特征:自然美、空灵美、整体美、含蓄美、实用美、浪漫美;最后提出了在现代中式家具设计中不仅要运用有形元素,更应融入传统文化的精髓,以形成中式家具艺术文化特质。     

论中国建筑遗产周边环境的法律法规建设

法律法规建设是建筑遗产保护中极为重要的一环。经过几十年的发展,中国建筑遗产保护的相关法律法规有了长足的进步。然而,对于遗产周边环境的保护和整治工作仍缺少关注。本文针对遗产周边环境的保护这一议题,从国家法律和地方法规两个层面出发,对当前中国相关法律法规的内容进行解析,并对相关法律法规中存在的问题进行总结并提出建议。     

Feature analysis of women's wedding dresses in new,style weddings in the Wu culture region in modern times北大核心CSCD

To further clarify the features of wedding dresses in new, style weddings in cities and towns of the Wu culture region, the author sorted out and made a statistical analysis of modern journals and periodicals as well as conducted a comparison in combination with diaries of celebrities and novels in modern times to collect 368 wedding photos in total in the Wu culture region. The analysis results indicate that wedding dresses in the Wu culture region were mainly of modified styles from 1859 to 1949, the development of wedding dresses went through the stages of unitary styles, mixed styles and diversified styles, in each of which there were also representative regular ways of matching. In general, wedding dresses were in simple, elegant and delicate styles, and the silhouettes kept up with popular western styles, showing a high level of acceptance of foreign cultures. The colors of wedding dresses tended to combinations of light colors, while traditional colors were gradually reduced. Besides, patterns of flowers and plants with thin stems and leaves were mainly used to decorate wedding dresses, showing the distribution features of scattering and covering. © 2018 China Silk Association.
