In this paper six bronze artefacts of the Eastern Zhou period to Han dynasty (770 BC ‐ 220 AD) with tin‐rich surface decoration in the British Museum collection were studied using a variety of analytical techniques. The decoration patterns include trellis patterns (菱形纹) on two swords of the Yue state, tiger's striped patterns (hu‐ban‐wen, 虎斑纹) on two swords from the Ba‐Shu region, a hexagonal star pattern (六角星纹) on a spearhead of the Wu state, and a cloud‐like pattern on a garment hook. The tin‐rich decorations on those objects were produced by deliberate tinning processes; at least three different tinning techniques were used, including the use of tin‐rich pastes for the trellis pattern of a Yue state sword and for the mottling decoration on the Ba‐Shu swords, amalgam tinning for the hexagonal star pattern on the spearhead of the Yue state, and hot tinning for the cloud‐like pattern of the garment hook. Different tinning techniques could have been applied to produce similar tin‐rich decoration patterns, and vice versa, a single tinning technique could have been used to produce different tin‐rich patterns on different objects. 相似文献

This article attempts to analyse mapping practices at the intersection of geography, black studies and literary studies, in order to reassess the political and pedagogical possibilities of mapping under late capitalism. I turn to Toni Morrison’s novel Beloved to track black cartographic practices otherwise obscured or, as Katherine McKittrick writes, “rendered ungeographic”. The novel offers a hidden and unauthorised archive for the often clandestine geographic practices that make possible fugitivity from the mechanics of “slaveholding agro‐capitalism” and its ongoing legacy. As an unofficial archive of black geographic practice, Morrison’s novel might itself be thought of as a map: a contemporary mode of memorialising the depth of place, relation, and navigation—a depth no two‐dimensional map can accommodate. Finally, this article demonstrates the valuable interventions that black studies and black creative production can make within the subfields of critical cartography and critical geography. 相似文献

AbstractAfter a 20-year hiatus (1955–1975) during which few archaeologists discussed fluoride dating, the method again received attention in the 1980s and 1990s when some argued for its validity. As a dating method, fluoride dating depends on the rate at which fluorine ions replace hydroxyl ions in osseous tissue. The rate of replacement is influenced by the properties of the skeletal part (SP), sediment chemistry (K), and sediment hydrology (H), and the replacement rate influences estimates of time. Calibrated AMS radiocarbon assays of 10 black bear (Ursus americanus) femora from a natural-trap cave in central Missouri are weakly correlated with fluorine concentrations, determined by neutron activation analysis in the 10 femora. Despite minimal variation in SP, K, and H, results indicate fluoride dating can be considered a valid dating method only in cases when the chronological validity of its results are confirmed with independent chronometric data. As similarities in fluorine amounts across specimens increase, provenience information and bone orientation data as well as fine resolution data on K and H become critical to the application of fluoride dating. 相似文献

本文探讨了有关唐代越窑青瓷刻划花的若干问题。作者以有明确纪年的唐代越窑刻划花青瓷以及相关的同一时期的有代表性的墓葬、窑址、遗址、沉船中发现的越窑刻划花青瓷为依据,总结了唐代此类瓷器工艺的演变规律和技法特征,分析了其与金银器的关系问题,并推测出此类瓷属于对外贸易的外销产品。 相似文献

20世纪60年代“班图斯坦”（黑人家园）的设立,是南非现代史上的一个重大事件。白人政权不遗余力地积极推行这一“创举”,在南非国内和国际上都引起了强烈的反响。“黑人家园”的设立可谓“意味深长”,它是种族主义的极端体现,在政治上“让步”的背后,是精心设计的经济上“分别发展”计划的实施。 相似文献

对唐代贾耽的地理(地图)著述的名目进行辨析,分析了"关中陇右及山南九州等图"、《九州图》、《海内华夷图》之间的关系,以及别录与通录的区别。指出《九州图》、《海内华夷图》是贾耽国图撰修总体事业在不同历史阶段的总称。并从地图学传统、方志学传统入手,探讨了贾耽地理(地图)著述的性质,对其中的地图学成绩进行了重新评价,进而从"近意就实,依稀像真"分析了贾耽地图学的滞后性,指出"古墨今朱"应只是文字注记的区别,并非通过图形绘制表达古今地理要素的差异,由此审视了中国古代地图史上图形绘制与文字注记的关系。 相似文献

In this article, I examine black queer nightlife in Soweto and its relationship with the making of black queer space in South Africa. Through an in-depth examination of the microgeographies of a Soweto stokvel party, I reveal the complexities of post-apartheid formations of race, class, gender, and sexuality. Employing the idea of usable space, I highlight quotidian practices of leisure as an important site for understanding cultural creativity within the marginalized spaces occupied by black South African queers. Performance and performativity are central to organizing nightlife spaces and reveal both the possibilities and limits encountered by black queers as they try to construct livable lives. 相似文献
