宋代是我国钱币的一个大发展时期,宋代钱币在我国钱币史上占有极其重要的地位.为了解南、北宋钱币的成分、显微结构的差异对铸币保存状况的影响,通过显微镜观察、合金成分分析、显微结构分析,对南宋和北宋各21枚钱币的保存状况进行了对比分析研究,以了解这42枚钱币的锈蚀状况、锈蚀原因,以及成分、显微结构的差异对铸币保存状况的影响.同时在分析研究的过程中,对北宋、南宋钱币的合金成分、铸造工艺进行了对比研究.研究结果表明,南宋钱币的保存状况比北宋的差一些,合金成分及显微结构的差异,是导致保存状况不同的重要原因.这些钱币主要是由铜、锡、铅铸造而成,分析结果进一步证实北宋钱币合金成分比较稳定,成分配比比较科学.而南宋成分数据比较分散,早期铜、锡含量较高,铅含量较低,晚期铜、锡含量较低,铅含量明显增高,合金品质大大降低.本研究可为了解当时的科学技术、社会经济形态进一步提供基本信息.  相似文献

安徽南陵出土部分青铜器研究   总被引:1,自引:1,他引:0  
安徽省南陵县是长江下游地区最早而且规模最大的冶炼中心之一,其古代矿冶遗址可上溯至西周晚期。本研究对南陵出土的不同年代和类别的青铜器样品进行了金相检测及合金成分定量分析。结果表明,只有容器存在铜铅二元合金和铜锡铅三元合金,但是热锻淬火的容器却不含铅,含锡量恰好位于适合该工艺操作并具有良好性能的区间。兵器、工具、车马饰均为铜锡二元合金,说明当时的工匠对于合金成分配比与性能的关系有明确的认识。越式鼎腹部样品具有热锻淬火马氏体组织,同样的金属结构还见于汉代铜锣等乐器、峡江地区战国中晚期青铜剑、江都大桥镇南朝青铜器窖藏出土的多件青铜容器,而镇江地区出土吴国青铜戈则具有铸造淬火组织,工艺稍有差别。这些器物中发现高锡青铜淬火组织不是偶然的,高锡青铜热锻淬火技术至少可以上溯至春秋战国时期,用以改善高锡青铜的机械性能。  相似文献

本研究对东下冯遗址出土的17件第三期冶金遗物进行了金相和扫描电子显微镜-能谱分析。其中1件附渣冰铜块的检测表明该遗址的铜有独立于锡、铅料的来源。熔铜渣及铜块的分析表明第三期时已经使用锡青铜,同时还有铅青铜、铅锡青铜、砷铜等合金种类的应用。青铜合金通过向红铜中添加锡、铅物料(可能含砷)得到,与二里头等遗址类似。  相似文献

我国从明中期开始使用黄铜钱币,一直到清末。过去,对古代铸币的科学研究主要集中于合金成分分析和铸造工艺两方面,对锈蚀产物和锈蚀机理的研究主要针对青铜铸币。黄铜的合金元素中较青铜多锌元素,其腐蚀产物与腐蚀行为较青铜有一定的差别,也较青铜更为复杂,然而现有的文献关于此方面的研究匮乏,特别是对于大气保存环境下黄铜钱币的锈蚀产物及锈蚀成因的研究基本空白。本研究通过多种分析手段包括X射线荧光分析仪(XRF)、扫描电镜能谱仪(SEM-EDS)和显微激光拉曼光谱仪(Raman)对国家博物馆馆藏一批传世明清各时期的黄铜钱币合金组成,不同颜色的锈蚀产物等开展科学分析。研究结果表明,嘉靖、隆庆和万历年的黄铜铸币,为Cu+Sn+Pb+Zn四元合金,平均含量Cu 66.4%,Sn 6.8%,Pb 10.4%,Zn 15.6%,并含有微量Fe,不含As。泰昌、天启和崇祯年间及清代各时期的黄铜铸币,主要为Cu+Pb+Zn三元合金,并含有微量Fe、As和Sn。这批黄铜锈蚀产物与常见的青铜锈蚀产物不同,最典型的是钱币表面蓝绿色和白色锈蚀物,经Raman和SEM-EDS分析并结合相关文献初步确认蓝绿色锈蚀物为一种含铜、钠...  相似文献

This article examines how the practice of learning geography, and the arenas in which knowledge-making takes place, can be usefully positioned within changing histories of the discipline. It contends that networks of action – understood through the intersection of social sites, subjects and sources – present a conceptual framework and narrative focus for the re-consideration of specific episodes from geography's past. The interventions made here are informed and illustrated by a 'small story' about the doing of geography. Based on different personal accounts, the story revives a series of events, encounters, dialogues and images dating back to the winter of 1951 at Glenmore Lodge, Scotland. This educational institution in the Cairngorm mountains offered children from urban areas the opportunity to learn field studies and the skills of 'outdoor citizenship'. Initially, the focus falls on Margaret Jack, a 14-year-old field-course participant. Her learning experiences are traced through personal letters, a diary and a field journal dating from that time, and her recent recollections of this event. Margaret's account dovetails with the story of her field studies instructor, Robin Murray. Robin's role is traced through his learning experiences as a geography undergraduate at Aberdeen University, and the recent recollections of Catriona Murray, his wife.  相似文献

The Knowledge of Debt: Law, Media Technique, and Everyday Experience in Liberal Capitalism. Performing an object such as ‘the economy’ hinges on practices of formatting knowledge. The article proposes to look at such instituting moments in connection with social conflicts over the legitimate rules of exchange. This is exemplified by way of recounting the story of the codification of Swiss bankruptcy law in 1889. In order to homogenize the legal procedures of debt collection and bankruptcy, two subject categories were instituted: ‘merchants’ and ‘non-merchants’. These different categories were thought to account for the diverging temporalities and spaces of credit exchange in everyday economic life. The introduction of the commercial register, a media-technical apparatus, enabled a formal distinction between ‘merchants’ and ‘non-merchants’. However, this boundary was contested and proved to be porose.  相似文献

Shells of two species of freshwater bivalve (Unio willcocksi Bullen Newton and Etheria elliptica Lamarck) from the predynastic Gerzean (Nagada II) Decorated Tomb at Hierakonpolis, Egypt have given dates of 5000±90 bp for the tomb, and 12,900±120 bp for an episode of Nile terrace accumulation (correlated here with the Sahaba-Darau aggradation event). The archaeological and geological significance of these results is discussed, together with an outline of problems associated with radiocarbon dating of shell. Comparisons are made with the few other radiocarbon dates available for the Predynastic period in Egypt and possible reasons for the presence of shells in the tomb are considered.  相似文献

The later post-glacial history of a valley in the chalk escarpment near Brook, Kent, is described, based on molluscan stratigraphy, archaeological evidence and radio-carbon dating. Differences in size and colour banding, respectively, of fossil and living representatives of two species of land snails, Pomatias elegans (Müller) and Cepaea nemoralis (L.), are correlated with climatic change during the post-glacial period. The problems of the use of fossil shells of these species as samples for radiocarbon dating are discussed.  相似文献

A Singapore-based economic geographer explores and analyzes the spatially uneven evolution of the Internet industry in China, arguing that the country's immense regional disparity in the provision of Internet services is best explained by the interplay of place- and path-dependence. The author demonstrates how the highly uneven regional endowments in relevant industrial and entrepreneurial resources have led to the substantial and persistent regional imbalance within China's emerging "new economy." His initial survey of the country's 100 leading Internet content providers (firms), identified from a listing of ca. 11,700 commercial websites, is selectively augmented to reflect an increase of over 70 million Internet users in 2007, reaching a total of 253 million in June 2008, and thus overtaking the United States as the world's largest Internet market.

This paper discusses the 1911 International Exposition in Rome and illustrates how this patriotic celebration of the fiftieth anniversary of the Italian Sate utilized symbolic landscapes of architecture and archaeology to promote nationalist sentiments of italianità and romanità centered on the young capital of Rome. Through modern art exhibitions at the Valle Giulia, scientific conferences at the Castel Sant’Angelo, archaeological exhibits on the Roman Empire in the Baths of Diocletian, and regional Italian pavilions in the Piazza d’Armi, exposition officials offered a complex representation of Italian national identity that was modern yet ancient, cosmopolitan yet bucolic, European yet regional, and imperial yet developing.  相似文献

Alexander the Great died in 323 B.C. from an unknown cause. By elucidating the nature of his death, we can better interpret various aspects of Alexandrian history. Alexander’s death may have ensued from the sequelae of a congenital scoliotic syndrome. It would therefore be of significance to note that one of the greatest leaders in history who conquered much of the then known world may have been suffering from a physical disability.  相似文献

Abstract

This paper is informed by Furse’s practice as a theatre maker in two fields of output that are connected by two factors: first, the presence of the woman patient — hysteric/subfertile respectively — within the clinical gaze; second, the significance of the womb to each pathology. In the treatment of each (explored in Furse’s theatre), lens based technologies play their part, whilst the cultural and medical can be seen to have overlapped to produce specific meaning with regard to Her body and its spectacularity. The article presents an overview of some of the key issues in precisely how the woman’s body becomes spectacular within this prosthetic medical gaze and how the medical — and theatrically designed spaces to represent these — become meaningful and potent proxemics that in turn inform medical/ theatrical spectatorship. Overarching nineteenth-century protocols at the Salpêtrière Hospital in Paris (where Furse’s Augustine (Big Hysteria) is set) to contemporary imaging technologies used in the treatment of subfertility with Assisted Reproduction Technologies (the topic of her Art of A.R.T. projects), it examines the way in which photography develops through cinema to X-Ray, ultrasound and then 3D/4D ultrasound to ‘capture’ the woman’s body in ways by which she becomes muted and exposed. These occular technologies that extend the gaze, first to an exterior subject and then, eventually, traversing the flesh without knife, lend specific performativity to the ‘patient’ women, within the context of hysterias and reproductive impairments respectively. Finally, issues of suspension of disbelief are addressed. The spectator’s faith in the screen-based image of Her spectacular body is interrupted in Furse’s work, which is also keenly interested in the effect of such imagery on the woman’s sense of Self. The historical and cultural leaps in this article argue that there is indeed a trajectory through the history of medical imaging since the first application of photography to anatomy to the more advanced scoping technologies of medical imaging today, and that in each era, the production of these images remain fraught with cultural implications.  相似文献

Alexander the Great died in 323 B.C. from an unknown cause. Physical depictions of this historical figure reveal the likelihood of a cervical scoliotic deformity. This is substantiated with the medical history and is correlated with his untimely death. For the first time, it is concluded that Alexander’s death may have ensued from the sequelae of a congenital scoliotic syndrome.  相似文献
