The Yuzhen Palace is one of the nine palaces in the Ancient Building Complex built by order of the Yongle Emperor during the Ming dynasty. The buildings were built with dressed black bricks. As a result of the planned national South–North Water Diversion project, the water level in the Danjiangkou Reservoir that surrounds the Yuzhen Palace was expected to rise by approximately 15 m. To avoid submersion of the site, three gates were elevated by 15 m in 2013 and other buildings dismantled, for later reconstruction. The characterization of the construction materials has therefore become of primary importance. Here, we present results on the plasters of the Longhu Hall. The analysis of materials involved a multi‐analytical approach combining optical and electron microscopy with X‐ray and vibrational spectromicroscopies and thermogravimetry. The results indicated the use of two earthen plaster layers and a whitewash finish coating applied over a thin preparatory intermediate layer to improve the adherence of the finish coating to the earthen plaster. Ramie and straw fibres identified in the earthen plasters were added to reduce shrinkage and cracking during drying. The raw materials used and the application technique pointed to a well‐established construction industry using traditional earthen building materials together with lime technology. 相似文献

Chang'an (now Xi'an) was the capital of the Western Han Dynasty and the starting point of the Silk Road. In the light of the importance of Chang'an as the centre of politics, economy and cultural interaction, the overarching question proposed in this paper is focused on its role in the mirror production and distribution network during Han period. On the basis of chemical and lead isotopic analyses of 34 Han mirrors, this paper discusses the potential existence of a mirror production centre in Chang'an. Meanwhile, a comparative study with mirrors uncovered from the south‐western frontier and from Central Asian and North‐East Asian countries offers new insight into these related issues. 相似文献

Microstructural and Componential Characterization of the Plating Technology on Chinese Han Dynasty Bronze Fragments

The bronze wares of the Han Dynasty excavated in Chongqing are decorated with plating patterns, maintaining an exquisite lustre right up to modern times after the covering patina is cleared away. In this paper, a plated fragment of the Han Dynasty from the Wushan County Museum was characterized by combining optical microscopy (OM), scanning electron microscopy with X‐ray energy‐dispersive spectrometry (SEM–EDS), X‐ray fluorescence analysis (XRF), X‐ray diffraction (XRD) and X‐ray photoelectron spectroscopy (XPS). The results showed that the bronze fragment was gilded with a ~ 3 μm thick gilded layer and a ~ 20 μm thick silvered layer. The high concentration of Hg and Hg‐rich intermetallic compounds confirmed the existence of mercury gilding/silvering technology, for example, Au9Hg in the gilded layer and Ag13Hg7 in the silvered layer. An ordered stripe structure was observed in the gilded surface, corresponding to the formation of rod‐like, intermetallic Au–Hg compounds. Specifically, a high concentration of Au was detected in the silvered layer. The exploration of gilded/silvered bronze casts light on this ancient technology and the benefit of identifying, protecting and reproducing it. 相似文献

Multi‐Scalar Practices of the Korean State in Global Climate Politics: The Case of the Global Green Growth Institute

The paper examines the significance of state territoriality and the related multi‐scalar practices of the state in the light of the symptoms of post‐politics exemplified in global environmental governance. The focus rests on the South Korean government's Green Growth (GG) strategy and the efforts to export this strategy as a role model to emerging economies worldwide through the establishment of the Global Green Growth Institute. We begin with the question why the Korean government is going global with a political program that is heavily disputed at home. We then study the practices by which the state manages to maintain its territoriality under the conditions of global climate change. Lastly, we discuss how multi‐scalar practices of environmental governance in the GG strategy are applied by state and non‐state actors both in Korea and abroad. 相似文献

张康 《华侨华人历史研究》2017,(2)
论文从离散族群的视角出发,简要介绍离散概念的历史沿革及其引入华侨华人研究领域的相关争议,并在回顾明清以降离散华人族群与祖(籍)国关系流变的史实基础上,验证尤西·沙恩等学者关于塑造离散者与祖(籍)国关系主要因素的理论假设,探讨了在历史变迁的大背景下,离散华人族群与祖(籍)国关系周期性亲疏变化的规律与原因。论文认为,离散理论的引入有利于我们更好理解全球化时代下的国家关系与族群认同。数百年来,离散华人虽身居异域他乡,但对于祖(籍)国各领域事务的关注、参与和影响却从未停止。伴随着时代变迁,其作为离散族群与祖(籍)国间的相互关系,也呼应于中华大地的浮沉兴衰和国际格局的调整不断变化。从祖(籍)国政府争取侨心的角度而言,离散群体的非政治属性回避了对国籍等敏感问题的区分,从而更有利于增进海外(入籍)华人群体的情感归属,也有助于在祖籍国文化的向心感召下创造更多的族群活动空间。 相似文献
