A mass of Longquan porcelain shards carved with ‘Guan’ or the dragon patterns were unearthed in the early Ming Dynasty layer of the Fengdongyan kiln site at Dayao County. These celadon shards were fired in the Hongwu and Yongle eras of the Ming Dynasty. In order to research the raw materials and firing technology of the imperial porcelain, 85 typical shards were analysed by energy‐dispersive X‐ray fluorescence (EDXRF). The results indicate that the contents of TiO2 and Fe2O3 in the body vary in the Hongwu and Yongle eras. Compared with Longquan glazes in the Southern Song Dynasty, the average values of K2O, Fe2O3 and TiO2 are higher, but that of CaO is lower in early Ming imperial porcelain glazes. Principal components analysis (PCA) shows that different degrees of elutriation of the same raw materials are the main reason for this difference in the Hongwu and Yongle periods. However, the raw materials of imperial porcelain glazes show no obvious changes and have inherited the earlier tradition. The production and firing technology of imperial porcelain reached a higher level and had not declined in the Early Ming Dynasty.  相似文献

Measuring Spatial Autocorrelation of Vectors   总被引:3,自引:0,他引:3       下载免费PDF全文
This article introduces measures to quantify spatial autocorrelation for vectors. In contrast to scalar variables, spatial autocorrelation for vectors involves an assessment of both direction and magnitude in space. Extending conventional approaches, measures of global and local spatial associations for vectors are proposed, and the associated statistical properties and significance testing are discussed. The new measures are applied to study the spatial association of taxi movements in the city of Shanghai. Complications due to the edge effect are also examined.  相似文献

The Chinese rites controversy of the seventeenth and early eighteenth centuries has been often studied, but hitherto mostly as a quasi-linguistic-and-technical dispute between the followers of Matteo Ricci, the legendary founder of the Jesuit China mission, and his many different enemies in the Catholic Church. In reality the involved debate was much more complex than that at every turn. To show this and more, this article takes a close look again at how and why Chinese terms and customs came to figure in Ricci's proselytising work in China, how they were challenged both inside and outside the Jesuit China mission, how the Chinese reacted and why, and what the debate revealed about the intriguing contrast of Chinese and European theism.  相似文献

刘向培 《中国地方志》2020,(1):55-61,M0005
方志为一地史事之渊薮,其中所载宋代学记为研究宋代官学、书院等教育组织的重要文献,不过因其分散保存在不同方志中,使用起来十分不便。曾枣庄、刘琳主编的《全宋文》收录了宋代绝大部分的记文,对宋代研究颇有助益,然此浩大工程难免挂一漏万。如《长洲县学记》为迄今所见宋人俞掞唯一存世文章,徐鹿卿《罗必元故宅记》等记文对宋代书院、祠堂、家族研究具有较高的参考价值,《全宋文》皆失收,今据相关方志对此9篇文章进行补遗,以期为宋代相关文献研究提供新的史料。  相似文献

In 2008 a new notebook manufacturing cluster was established in Chongqing in western China. By 2013 it accounted for some 25% of world output by volume. Chongqing’s ability to attract this manufacturing supply chain was driven by several factors that permitted strategic coupling: the existence of complex networks of cooperation and economies external to the firm but internal to contemporary global production networks; changed conditions in southeast and east China; and the creation by Chongqing Municipal People’s Government with central state support of hard and soft infrastructures and externalities that drove down logistic and production costs and permitted constant product innovation.  相似文献

By focusing on Guangzhou's street‐vending policy transformation, this article explores how exclusionary practices of urban politics in China are undermined by those who it seeks to exclude and the progressive political climate that questions the exclusionary framework. The exclusion of street vendors in Guangzhou has been led by the National Sanitary City campaign as a revanchist project. It has been discovered that while the exclusionary strategies are rendered difficult to operate due to the resistance of street vendors who develop a flexible, individualized and small‐scale activism to maintain their livelihoods, the discourse of social harmony at national level has driven local authorities to seek alternatives expected to alleviate social resistance and address people's livelihoods. However, rather than an overturn of the punitive framework, an ambivalent approach, recognized in a recent critique of revanchism, has been adopted to mediate the tension between the needs to retain attractive city images and address the livelihoods of the poor in Chinese cities.  相似文献
