This article describes a new technical scheme to apply Trombe wall technology for wall conservation in modern historic buildings. The feasibility, key construction technologies and operating conditions in different seasons were demonstrated by an actual case in Beijing. Key findings show that the technical scheme not only protects the skin texture of the wall but also makes full use of passive solar energy. Energy consumption simulation results show that saving energy in winter is significant. Compared with the original building, the total energy consumption of the building that adopted the technical scheme was reduced by 10.77%, the heating energy consumption was reduced by 21.86%, and the cooling energy consumption was reduced by 1.02%. The research findings provide new inspiration and reference for studies on the protection of modern historic buildings, and serve as a technical reference for architects. 相似文献

对于清初文学和文化研究来说,2007年嘉德春季拍卖会上的一件古籍拍品似应引起格外关注.此拍品名<霜哺篇>,乃袁氏为弘扬寡母吴氏养育之恩而遍征名人赠言所成,上存120馀位当时名人题咏题跋的手迹和印鉴款识.据说原作共有40馀卷,至道光年间已散残,顾开增重付装池成三卷,光绪年间归常熟翁同稣收藏.关于这件拍品的辑者和内容,有关介绍甚为简略,仅言为"明末清初常熟孝子袁重其为感念其母寡居贞节、悉心养育之恩所辑"[1],且多有不确. 相似文献

清代的旗人教育,设有专门教授外国语言文字的旗学,如俄罗斯学、朝鲜译学,某些旗学还设有外文专业,如回缅官学的缅甸文专业、内务府官学中的拉丁文专业。清末同文馆,也有旗人子弟学习英、法、俄、德、日本等国文字,这是适应当时的行政需要而设置,也是中国古代教育史上值得注意的特殊内容。鉴于学界尚无专文系统介绍,本文以专题形式对这类学校及专业的设置、教师及学生的情况分别作了某些考察。 相似文献

刘祁出身于金代号称"丛桂蟾窟"的文学世家,以能文名冠当时,在史学和哲学方面也多有建树.刘从益和刘祁、刘郁父子三人为后人留下了必传之作,与汉代著名学者刘向、刘歆有许多相似之处,而在文学界的地位则与宋代三苏相类,为保存古代文献,弘扬道学,振兴金元文风做出了卓越贡献. 相似文献

In the Majiayao cultural stratum of the Lajia site in Minhe County, Qinghai Province, much earthenware of rich variety and strong character has been found, among which the most special item is a suspected glazed white ceramic fragment. This study investigates this ceramic sherd and many other overfired objects. Energy‐dispersive X‐ray fluorescence spectroscopy, scanning electron microscopy – energy‐dispersive X‐ray spectroscopy, X‐ray diffraction and thermodilatometry were employed to analyse the composition, microstructure, phase composition and firing temperature of the white ceramic. In addition to large condensed glaze droplets, the white ceramic showed a thin and uneven glaze layer, which might represent the earliest results of the exploration of glaze‐making technology by Lajia inhabitants, and provide a new perspective on the study of the origin of Chinese proto‐porcelains. 相似文献

Previous studies on modern historic buildings protection have been mainly conducted from the view of building history, culture and aesthetic, but rarely focus on the green building technology and energy-saving. With the increasingly serious crises of environment and energy, it is valuable to research how to carry out ecological protection to effectively reduce energy consumption in modern buildings while ensuring the authenticity and readability of building heritage information.

Long-duration ground motions may be down-sampled to speed up the computational process. However, using ground motions with large time step (Δt) would inevitably bring in numerical errors. The influence of Δt on the site effect and structural response analyses was quantitatively examined in this study. The results show that the nonlinear site response method is more sensitive to a change of Δt than the equivalent-linear method. For the structural analysis, the impact of Δt is highly dependent on the magnitude of damage parameters. Thus, using input motions with Δt as 0.005 s is recommended for structures subjected to strong shakings. 相似文献

There is increasing interest in understanding China's environmental governance through the lens of governmentality. This article contributes to that discussion by using the Foucauldian analytical apparatuses of discipline and security to understand China's governance of farmland. It argues that the Chinese state applies these two apparatuses simultaneously: on the one hand, it disciplines and deters local states from illegal land grabs by utilizing surveillance tools such as remote sensing and national land surveys; on the other hand, it relies on indirect governance through the land quota market to achieve grain security, transforming both local states and peasants into autonomous market players, and reconstructing China's rural landscape by launching mass peasant relocation programmes. The study also reveals the contingent effects of those power tactics: the state's governance is compromised by the local states’ counter‐conduct, such as data fabrication and concealment, and by the peasants’ denial of their new subjectivity as market players. When the tactics are effective, as in the case of local states actively assuming roles of land quota producers and traders, the villages and peasant households suffer from deprivation of land rights. 相似文献
