上林湖越窑在晚唐、五代时期烧制出了釉色青灰、色泽莹润的秘色瓷,迎来了越窑瓷业的巅峰。以上林湖后司岙越窑遗址出土唐、五代秘色瓷和普通青瓷科技分析数据为基础,采用当地沉积黏土、草木灰等为主要原料开展了秘色瓷的工艺模拟实验研究,重点对比了不同类型匣钵和装烧方式对模拟烧制青瓷釉的影响。此外,通过色度分析仪及光电子能谱仪等对模拟烧制青瓷釉色度和着色物质铁的价态进行测试,探讨了瓷质匣钵口沿封釉装烧秘色青瓷的作用和机理。越窑青瓷实验考古中,对七件青瓷样品进行了光电子能谱分析,结果显示,采用瓷质匣钵口沿封釉装烧青瓷釉的Fe2+/Fe3+比值为2.8,远大于普通匣钵内青瓷釉的0.57。结合考古实地调查研究,可以推断这是越窑秘色瓷呈色不同于普通青瓷的主要原因。 相似文献

出土于湖南衡阳何家皂北宋墓的纺织品上观察发现有灰蓝色固体物质附着,为查明其性质,采用扫描电镜-能谱法、激光拉曼光谱法和X射线衍射法结合能量色散X射线荧光光谱法和光学形貌观察等手段进行科学分析。结果表明,该物质为磷酸亚铁矿物——蓝铁矿[Vivianite:Fe_(3)(PO_(4))_(2)·8H_(2)O],其多形成于富铁、富磷、有机物含量较高且贫硫的缺氧还原沉积环境中,微生物活动亦对其生成有影响。该矿物的发现对墓葬环境特征与保存状态的研究有指示意义,在考古遗存中或可作为判断特殊埋藏条件的标志自生矿物之一。 相似文献

Imaginative geographies engage with the understanding and experiencing of place and place‐based social and cultural specificities through a process of re‐creation and reproduction. In this article, we explore the imaginative geographies of Lugu Lake, a tourist destination in China's Yunnan Province, and of the Mosuo people, the local minority which practices a unique marriage system. We investigate how Mosuo society has been imagined in popular discourses and representations through two cultural labels: matriarchy and free sex. We also discuss how the imaginative geographies of Lugu Lake have restructured the encounters between the local people, especially the young men, and the incoming tourists in the context of tourism development. We interrogate the complex processes of identity formation in which both the tourists and the indigenous people renegotiate and reconstruct their cultural identities within various inside–outside connections and interactions. Our central argument is that the sex encounters between tourists and the local Mosuo are conditioned by popular imaginative geographies of the sexual practices of the Mosuo. But the encounter in tourism between the gazer and the gazed also accommodates complex identity formations and the renegotiation of social relations. The empirical observations are twofold: first, the locality of Lugu Lake has been reproduced with folk and tourist imaginative geographies into an erotic frontier of free sex; second, we also argue that the geographical imagination in this case is a reciprocal process which involves the local Mosuo's renegotiation of place‐based identity, in a pursuit of imagined progress and modernity. 相似文献

China has a long history of sheep husbandry, and has several indigenous sheep breeds. However, the exact geographic origin of Chinese domestic sheep remains unclear. To provide valuable genetic information for origin of Chinese domestic sheep, we performed an ancient DNA study on 22 sheep excavated from four Bronze Age archaeological sites in Northern China. Two lineages (A and B) were observed in ancient Chinese sheep, of which lineage A was predominant reaching a frequency of 95.5%. Furthermore, phylogenetic network showed that the most frequent haplotype in ancient sheep was the founder of lineage A. These results suggest that Lineage A may hold the key to understanding the origin of Chinese domestic sheep. Sequence sharing and principal component analysis showed that the ancient Chinese sheep had a close affinity to modern Chinese sheep. However, there was no significant breed structure among three modern Chinese sheep groups, making it difficult to determine their relationship to ancient Chinese sheep. Lastly, our results imply that ancient DNA analysis could provide a new way to investigate prehistoric East-West contact. 相似文献
