Palace lanterns were important and highly visible decorations in the imperial palace in Beijing, China, during the Qing dynasty (1636–1912). Most lanterns had colourful tassels made of fibres. The study performed a comprehensive investigation of the materials and dyes used for palace lantern tassels preserved in The Palace Museum, Beijing. Eight samples with different colours, including yellow, green and red, from five palace lanterns were analysed. By using ultra-performance liquid chromatography combined with time-of-flight mass spectrometry, the compositions of the dyes were identified quickly, and thus the dyes' origins were explored. A X-ray fluorescence spectrometer assisted in the detection of whether a mordant was used during the dyeing process. As a result, the tassels were all made of silk, discovered through the use of microscopic observation and micro-Fourier transform infrared spectrometry analysis. Different dyeing techniques were found in these tassels: yellow tassels were dyed by cork tree or turmeric by a direct dyeing method; greens were dyed by pagoda bud with an iron mordant, or by the combination of cork tree and indigo using multi-dyeing method; and red tassels were coloured with different acid red industrial dyes. These results provide valuable data for the conservation of ancient textile tassels and contribute to the investigation of other hanging tags. 相似文献

This article examines the intense debates over the New Criminal Code of Great Qing (Da-Qing xin xinglü) in the National Assembly (Zizheng yuan) during the Qing empire’s New Policy Reform (1901–11). The focus is on the conflict between those who drafted and supported the new code and those who expressed reservations, especially over reform of the laws on filial piety and fornication. The issue of reconfiguring the family and social order through law was closely related to the overarching agenda of twentieth century legal reform in China—making an empire that “ruled through the principle of filial piety” into a modern nation-state that had direct relationships with its citizens. More importantly, an analysis of the late Qing debate over family law enables this article to problematize such concepts as “Chinese” and “Western” during this crucial moment of China’s empire-to-nation transformation. It showcases the paradox of China’s modern-era reforms—a contradiction between imposing Western-inspired order with a largely indigenous logic and maintaining existing sociopolitical order in the name of preserving national identity. 相似文献

南宁市房地产价格分布规律的机助制图研究与开发方向的探讨 总被引:1,自引:0,他引:1
南宁市房地产业经历了由沉寂、复苏、火爆到稳步发展的过程.各公司开发的房屋类型相近,但价格差异却很大,价格分布呈现明显的规律性:一是城市中心价格高,边缘与郊区价格低;二是东部城区价格高,西部城区价格低.主导价格分布规律的三大影响因子是地理位置、交通便捷程度和生态环境质量.南宁今后的房地产开发和城市规划建设一要顺应价格分布规律,优地优用、保障房地产开发的高效益;二要加强交通设施建设和环境保护.促进全市房地产的升值;三要因势利导,发展城市副中心,逐步形成多中心的城市建设格局。 相似文献

Shear walls are important lateral force-resistant components of tall buildings. Hence, a reliable numerical model that can accurately represent the mechanical characteristics and large deformations of shear walls is critical for realistic collapse simulation of tall buildings. Based on the theory of generalized conforming element, a high-performance quadrilateral flat shell element, NLDKGQ, accounting for the large deformation using the updated Lagrangian formulation, is proposed herein and implemented in OpenSees. The reliability of NLDKGQ is validated using classical benchmark problems and reinforced concrete specimens. In addition, its capability in simulating the collapse of a tall building is also demonstrated. 相似文献

Zooarchaeologists frequently measure taxonomic evenness to document subsistence change and to understand the response of faunal communities to paleoenvironmental change. Although the measurement of evenness is commonplace, there are numerous challenges involved. Evenness indices are sensitive to changing richness, and by extension sample size, and various indices respond differently to changing taxonomic abundances (i.e., changing evenness). To refine protocol for comparing assemblages of varied sampling effort and identify indices that may be more useful for zooarchaeological applications, we examine the quantitative behavior of the widely used Shannon evenness and Simpson indices and two others more commonly used by ecologists. These indices are examined in relation to varied richness, sample size, and taxonomic abundances. We show that although zooarchaeologists are concerned with identifying and correcting for the effects of sample size on evenness, it may be appropriate to instead focus on how richness modulates evenness. Based on our analyses, we recommend the Simpson index for most zooarchaeological applications, except when comparing evenness across assemblages that are very even. 相似文献

This article explores the possibility of institutional multilateralism in Northeast Asia from the perspective of “emergent peace”. The main argument of the article is that a self-organising peace process arising from institutional multilateralism is constrained and enabled by the existing “morphogenetic fields”, the formative social spheres of collective action. Similar ideas or initiatives that are pursued by an agent/agents may result in different consequences depending on the characteristics of the morphogenetic fields. This argument is examined through two case studies. The first is Jean Monnet in Europe, who played a pivotal role in the establishment of the European Coal and Steel Community (ECSC), and the other is Ahn Jung-geun in Northeast Asia, who proposed the detailed ideas of pan-Asianism akin to Monnet but failed to play a role as an agent. The case studies demonstrate that the feature of the morphogenetic fields is determined by the characteristics of embedded agency at a critical juncture, while the agency is bounded by the particular spatial and temporal conditions of the morphogenetic fields. In search of an emergent peace process in Northeast Asia, this article particularly highlights the Six-Party Talks, arguing that they are a by-product of, and an alternative to, the San Francisco System. 相似文献

为了探索一种适宜的遗址文物保存方式,在四季分明,气候变化较为剧烈的西北地区的文物遗址环境区,达到最大程度保护遗址文物的目的,通过对开放式的秦始皇兵马俑博物馆一号坑遗址环境的建筑结构、温度和相对湿度变化及大气颗粒物进行分析监测,并与封闭式汉阳陵博物馆外葬坑的结果进行对比研究,发现单从环境温湿度恒定、阻挡室外颗粒污染物和气态污染物的角度来讲,封闭式的汉阳陵博物馆存在明显的优势。但依然不能阻止温湿度的季节间波动和室外空气污染物渗入的威胁,同时还要预防室内污染的发生,并且出现玻璃护围内部结露,文物大面积返碱等问题,并不能很好解决文物良好保存和观展目的。所以依旧需要探索一种适宜的遗址文物保存方式,既能保持文物保存环境的温湿度的相对稳定和洁净,又能缓解全封闭玻璃护围内部结露,文物大面积返碱等问题,最大程度延长遗址文物的寿命的同时,满足观众参观的需求。本对比研究结果可为今后的设计提供参考。 相似文献

AbstractThis article discusses the issue of the Ming army's maritime shipping of supplies during the second stage of the East Asian War of 1597–8. Despite the lack of historical sources and difficulty in finding accurate numbers, Zhang Yangmeng's 張養蒙 memorials include records of maritime transport decisions, implementation, effectiveness, and limitations and are of great help to filling in the blank areas of research in Ming army logistics. 相似文献
