一批中国古代镶嵌玻璃珠化学成分的检测报告 总被引：4，自引：0，他引：4
结合外束质子激发X荧光（proton induced X-ray emission,PIXE）和能量色散X射线荧光（energy dispersive X-ray emission,EDXRF）分析技术,对中国新疆、湖北、四川、广东出土的古代镶嵌玻璃珠的化学成分进行了检测.结果表明：新疆拜城克孜尔墓地出土的西周-春秋时期镶嵌玻璃珠为CaO-MgO-SiO2玻璃,战国时期中国境内的PbO-BaO-SiO2和Na2O-CaO-SiO2镶嵌玻璃珠是同时存在的.本文亦对相关问题进行了一些讨论,并提出了部分今后的工作建议. 相似文献

The objective of this paper is to document the ongoing shift from communicative to cultural memory of war and post-war events in the Czech Republic by using an example of a local struggle about a memorial for German inhabitants of a Czech town killed in June 1945. Thanks to an anthropological and social geographical approach based on interviews, family memory research, observations, and analysis of archive materials, it is possible to reconstruct the local and international sources of the post-1989 collective memory of the German past in Central Europe. This memory is still in constant conflict with the pre-1989 version of Czech national history which had contemptuously marginalized its German component. The communicative memory of the German past has entered the public space and tries to become a permanent part of the Czech cultural memory, but it is not a straightforward process, mainly due to the continuously strengthening nationalistic framing of memory within Central Europe. 相似文献

GIScience and GISystems have been successful in tackling many geographical problems over the last 30 years. But technologies and associated theory can become limiting if they end up defining how we see the world and what we believe are worthy and tractable research problems. This paper explores some of the limitations currently impacting GISystems and GIScience from the perspective of technology and community, contrasting GIScience with other informatics communities and their practices. It explores several themes: (i) GIScience and the informatics revolution; (ii) the lack of a community‐owned innovation platform for GIScience research; (iii) the computational limitations imposed by desktop computing and the inability to scale up analysis; (iv) the continued failure to support the temporal dimension, and especially dynamic processes and models with feedbacks; (v) the challenge of embracing a wider and more heterogeneous view of geographical representation and analysis; and (vi) the urgent need to foster an active software development community to redress some of these shortcomings. A brief discussion then summarizes the issues and suggests that GIScience needs to work harder as a community to become more relevant to the broader geographic field and meet a bigger set of representation, analysis, and modelling needs. 相似文献

Bluff Harbour, in southern New Zealand (Murihiku), is the southernmost location of Polynesian adze production. Here, an industry developed during the colonisation phase based on the exploitation of numerous sources of argillite – a fine‐grained, homogeneous rock with conchoidal fracture properties. Argillite from the Bluff and Riverton sources was a major attractor during the earliest period of human occupation and Bluff argillite adzes were distributed widely throughout the lower South Island. The most extensive sources of Bluff argillite are on Colyers Island, where there is evidence of quarrying and preform production along much of the coast. The sites on Colyers Island were surveyed as the first part of an archaeological investigation of quarrying and adze production in Bluff Harbour. The quarried boulders, outcrops and artefact distributions at these sites indicated that the raw material was exploited by highly organised and skilled craft specialists. The initial stages of adze manufacture were undertaken at the quarry, and then preforms were taken to multipurpose camp sites around the harbour for finishing. Adze blanks on Colyers Island were made from large flakes, tabular blocks and cobbles, using imported hammer stones. This paper documents the significance of Colyers Island as an important adze production complex in New Zealand. 相似文献

本文报道了用ENGLE-Ⅱ微探针能量色散型X荧光光谱（EDXRF）技术测定一批青瓷残片中的16种元素氧化物的含量．其残片来自浙江杭州地区南宋的郊坛窑和老虎洞窑。由主量元素判别方程。值表明,郊坛和老虎洞青釉瓷均属官窑制品,与龙泉民窑产品有很大差别。从主成分统计分析看出．郊坛下官窑与老虎洞官窑的瓷釉成分有明显不同,但其胎质成分的分布却有部分的重叠。这显示两类同属官窑的制品,其釉料可有不同的矿物组合。但胎料有时会交流使用。从釉层、中间层、和胎层的Al2O3和CaO的含量变化数据表明,郊坛下官窑和老虎洞官窑的青瓷制品有厚度分别为120-140um和230-240μm的中间层,反映出烧造工艺上有一定的差别。化学成分鉴定证实了考古工作者认为老虎洞窑实为史书记载的修内司官窑的观点． 相似文献

2017年,山东寿光机械林场遗址Ⅰ区、Ⅲ区共清理各类遗迹30余处,包括灰坑、盐井和盐灶等。出土器物有圜底瓮、鬲、豆、盆、罐、瓦等,绝大部分为残片,以圜底瓮残片为大宗,器物年代集中于战国早中期。初步判断该遗址为战国时期一处煮盐作坊。 相似文献

中国先民使用红色颜料的历史悠久,最早可以追溯到新石器时期,它在中国的物质生产和文化发展中发挥了重要的作用。在2006年发掘的大房郢水库汉墓群中发现了两种红色颜料,通过采用X射线衍射、X射线荧光分析和傅立叶变换红外分析等分析方法对其进行了研究,发现它们是赤铁矿(α-Fe2O3)和朱砂(HgS),其用途分别为制造化妆品和红色漆膜。 相似文献
