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 attempts to advance the research on industrial districts and regional development through a study of the restructuring of the clothing industry in Wenzhou Municipality, a regional driver of the Chinese economy. Wenzhou is known for the Wenzhou model of development traditionally centred on family‐owned small businesses embedded in local institutions. The clothing industry is one of the leading industries in Wenzhou, and a cluster with national significance has emerged, where most of the production components can be purchased locally. However, the industry has been scaled up nationally and internationally, with the expansion of sales networks and production facilities across China, and to a lesser extent, abroad. This restructuring has changed the endogenous nature of industrial clusters/districts. The restructuring challenges the orthodox notion of the Wenzhou model and the New Regionalism literature, particularly the orthodox notion of Marshallian industrial districts that overly emphasizes small firms and local assets, and the global production network perspective that highlights coupling with global lead firms in regional development.  相似文献

This paper examines the theoretical implications of quantity-discounted transportation rates on the optimum location decision of the firm. It shows that the linearly homogeneous or homothetic production function is not a sufficient condition for the independence between the optimum location and the output level, unless (i) the elasticities of transportation rates with respect to quantity shipped are constant and identical, and (ii) the ratios of marginal products 60 the marginal transportation costs are equal for each input.  相似文献

目 次 一 救亡图存与重建古史:早期中国考古学的历史选择 二 从考古学文化到区系类型:中国考古学的探索与发展 三 坚定文化自信:新时代考古学的历史使命 习近平总书记"9·28"重要讲话深刻阐述了我国考古工作取得的重大成就和重要意义,为新时代中国考古事业发展指明了前进方向,也为如何构建中华民族历史、认识中华文明丰富内涵、坚定文化自信提供了理论依据[1].考古学在中国是近代化的产物,从它自西方传入中国、并且植根于中华大地这片沃土伊始,一方面在学术目标、理论建设和田野实践等环节就不断形成自身的历史传统,不再是西方考古学的翻版,而是努力朝着建设中国特色和中国风格的考古学体系迈进;另一方面,在不同的时代,中国考古学者也承担起不同的历史使命,不断续写新篇,继往开来,为中华文明和世界文明做出了独特贡献.回顾百年中国考古学史,每当时代发展的重大转折关头,中国考古学都在顺应历史变革、引领社会思潮、坚定文化自信上起到重要的历史作用.  相似文献

迄今已有2 700多年历史的铜鼓,是南方少数民族地区节日、喜庆、兵事、婚丧、祭祀、礼乐等场合使用的一种重器。为了对锈蚀状况做出科学的现状评估,为器物保护修复技术路线的制定和修复工作的开展提供科学指导,对玉林市博物馆馆藏7件铜鼓综合运用了体视显微镜、金相显微镜、激光显微拉曼光谱仪(RS)和环境扫描电镜及能谱仪(ESEM-EDAX)等仪器进行了金相组织和合金成分分析以及锈蚀产物的分析。分析结果显示:7件器物皆为泥范铸造成型,未见热、冷加工处理现象。7件铜鼓皆为铅锡青铜合金,总体呈低锡高铅的特点。组织形态呈典型α固溶体树枝晶偏析,锡含量处于6.0%~12.2%,分布较为集中,处于中等含量水平(5%≤Sn15%);铅含量处于14.4%~28.2%,铅含量普遍较高且分布较为集中,处于中高铅(10%≤Pb15%)和高铅含量(Pb≥15%)水平,合金中高铅含量配比应为工匠有意合金配比选择;铜鼓的腐蚀类型为α固溶体富铜相优先腐蚀,保存环境主要是富氧、少氯,铜鼓表面锈蚀产物主要为绿色孔雀石和蓝色蓝铜矿以及氧化物,有少量白色白铅矿。在保护修复工作中对于这些无害锈可保留,不予处理,并注重防氧。对于铜鼓表面夹杂泥土,需进行清洗去除。研究结果可为器物保护修复技术路线的制定和修复工作的开展提供科学指导。  相似文献
