本研究旨在研究秦始皇帝陵园出土彩绘青铜水禽锈体的结构形貌及其形成原因。采用扫描电镜能谱(SEMEDS)、X射线荧光光谱(XRF)、金相显微分析和离子色谱分析(IC)等多种分析手段,对青铜水禽锈体的组织结构及其埋藏土壤进行了分析检测。结果表明:高湿、火烧、人为破坏的特殊埋藏环境是该批青铜水禽严重矿化的主要原因,而有些矿化严重的部分为稳定的粉状锈蚀物,并非传统意义上的“有害锈”;从组织的微观腐蚀特征来看,铸态枝晶结构的样品α相优先腐蚀;而铸后受热组织则呈晶间腐蚀的特点,腐蚀由晶粒间界向晶粒发展;锈体层状结构的产生与Cu2O溶解产生空隙,并在合适的环境条件下生成了孔雀石有关。  相似文献

Skeletal trauma often has been utilized to examine facets of inter- and intragroup violence. Eighteen skeletal elements from Tatham Mound are considered in this study, which exhibit wounds similar to documented cases of trauma caused by edged metal weapons. Tatham Mound is a sixteenth century mortuary site in central Gulf Coast Florida and is located within the reconstructed zone of contact with the Spanish explorer Hernando de Soto. Macroscopic and microscopic analyses of skeletal elements are conducted in order to distinguish trauma due to edged metal weapons from other perimortem and post-mortem bone modification. The damage on elements from Tatham Mound is compared with documented cases of trauma from edged metal weapons as well as medieval European skeletal remains exhibiting trauma due to edged metal weapons. It is concluded that some of the observed cases are probably due to metal weapon wounds inflicted by the Spanish explorers.  相似文献

The Middle (Kretuonas 1B), Late Neolithic (Zemaitiške 1 and Zemaitiške 2) and Old Bronze Age (Kretuonas 1C) settlements near Kretuonas Lake (Svencioneliai district, Reskutenai village) yielded many artefacts of bone, antler, horn and teeth (750 in total). In the Kretuonas 1B assemblage, deer bones accounted for 50.5 per cent, elk bones 19.7 per cent and boar bones for 27.7 per cent of the total. In the Zemaitiške 1 and 2 settlements the respective portions were 27.7 and 62.0 per cent deer, 6.8 and 20.0 per cent elk and 10.1 per cent boar. In Kretuonas 1C the proportions were 10.9, 36.0 and 7.5 per cent respectively. In the Kretuonas 1B settlement 32 artefacts were identified, 16 from deer bone, four from elk and four from boar. In the Zemaitiške 2 settlement there were 114 artefacts of which 57 were identified to species. Of these, 39 were from deer, eight from elk and four from boar. Finally, in the Kretuonas 1C settlement, of the 531 artefacts found, 120 were identified to species and of these 49 were from deer, 44 from elk, nine from boar and nine from bear.  相似文献

2018年山东省邹城市邾国故城西岗墓地一号战国墓出土了一件锈蚀严重的带钩,为了全面了解其材质特征和保存状况,对其进行了X光探伤、X射线荧光光谱分析(XRF)、X射线衍射分析(XRD)和扫描电镜—能谱仪分析(SEM-EDS)。结果显示这是一件较为罕见的错金嵌绿松石青铜带钩。为了揭示其艺术价值和科学价值,在科技检测基础上开展了保护工作。在保护过程中,通过对带钩和金丝形貌特征的显微观察可知,金丝的横截面形态既有倒三角形也有倒梯形,而且较宽的金丝是由单根细金丝折弯盘绕而成。这些独特的错金技术特征在以往公开发表的资料中尚未见报道,说明古代错金技术存在多种具体实现方式,这为错金银工艺研究提供了新的珍贵资料。  相似文献

This paper examines the intellectual traditions and recent advances in the archaeology of the Bronze and Iron Ages of the South Caucasus. The first goal of the paper is to provide an account of the scholarly traditions that have oriented research in the region since the mid-nineteenth century. This discussion provides a detailed case study of an archaeological tradition that arose within the context of Russian and Soviet research—traditions still poorly understood within Western archaeology. Yet archaeology in the South Caucasus was strongly influenced by international research in neighboring southwest Asia, and thus the region’s intellectual currents often diverged from the debates and priorities that predominated in Moscow. The second goal of this paper is to outline the primary issues that orient contemporary work in the region from the Neolithic through the Urartian period. My interest here is both didactic and prognostic. While I am concerned to fairly represent the primary foci of contemporary regional scholarship, I also make an argument for a deeper investigation of the constitution of social life. Such studies are critical to the advancement of archaeology in the South Caucasus over the coming decade.  相似文献

青铜编钟起源的探讨   总被引:1,自引:0,他引:1  
青铜编钟的起源若不梳理清楚,就难以论述明白青铜编钟的发展脉络。基于现有出土物和献记录,讨论了青铜编钟起源的若干问题,指出:青铜编钟可能滥觞于陶铃,其后陶寺铜铃的出现,为青铜编钟的产生发展奠定了一个重要的基点,而青铜编钟的真正起步是从晚商铜铙开始。对二里头铜铃至晚商铜铙之间存在的缺环,中提出了一种可能性的解释。有人认为南方铙是中原铙南传的结果,本工作则根据中原铙别于南方铙的出土成编等现象,提出了中原铙是借鉴南方铙发展而来的观点。对南方铙和中原铙之间差异、甬钟等的由来、青铜编钟的起源所反映的礼乐意义及其带给今人的启示等问题亦进行了探讨。  相似文献

近年来中国发展核武器的问题在中苏关系的演进中,特别是在中苏关系破裂中的作用引起学术界的重视.作者根据陆续出版和解密的中国和苏联方面的相关文献档案,对中国发展核武器的基本战略考虑、中国核武器的发展与中苏关系演进的互动关系、苏联政策的变化的动因以及此种变化对中苏关系破裂的影响进行深入分析:认为中国核武器的发展与中苏关系的破裂是一个互动的过程.中国发展核武器在当时背景下,只能争取苏联的援助,苏联向中国提供发展核武器的技术,有其特殊历史背景.1958年下半年后,随着两国在意识形态、对时代和国际形势以及核武器的态度等问题产生重大分歧,这些事件直接或间接促使苏联停止援助中国发展核武器.这成为中苏关系破裂的重要标志,也成为日后中苏论战的一个重要论题.  相似文献

试论美国对中国核武器研制的评估与对策(1961-1964)   总被引:2,自引:0,他引:2  
本文利用美国政府最新解密材料,对1961-1964年间美国对中国进行核试验的时间、地点、核原料及运载能力的侦察情况进行了阐述.并对美国对中国研制核武器的评估和对策进行分析,其评估与对策是建立在过分夸大中国核威胁的基础之上的.中国研制核武器是为了保卫中国人民免受核威胁,而且,中国在任何时候、任何情况下都不会首先使用核武器.  相似文献

望京楼遗址是夏商时期重要邑聚,为了解该遗址铜器制作工艺水平,通过金相显微镜和扫描电镜对2010~2012年新郑望京楼遗址出土的青铜器样品进行组织与成分分析和探讨。该批铜器未见青铜容器,仅有小件工具和兵器。但仍可初步反映出望京楼遗址出土的青铜器材质多样化和加工方式非单一性;对望京楼铜器分析反映出该区域使用锻打应该有了一定积累并在此基础上能依据材质和器物薄厚、尺寸选择工艺,对锻打技术认知度较高。望京楼铜器具有的原始性,应属于铜合金使用的早期阶段。研究表明,商代对于器物成分与性能关系的认识程度比之前得到提高。器物是本地制作还是外来还需要更多材料证明。  相似文献

Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis was undertaken on 37 blue glass beads excavated from a tomb in the southern Faiyum region of northern Egypt. The tomb was undisturbed, contained the remains of seven females and two children, and dated between the reigns of Amenhotep I (1525–1504 bce ) and Tuthmosis III (1479–1425 bce ). The glass beads were coloured by copper and the trace element concentrations were compositionally consistent with glasses from Mesopotamia rather than from Egypt. Therefore, these glass beads represent a rare example of Mesopotamian glass to be discovered in Egypt, in addition to being some of the earliest glass found. Gurob is known to have been the site of a ‘harem palace' established in the reign of Tuthmosis III, the implication being that these beads represent luxury items transported to Egypt by high-ranking foreign women, possibly in connection with the harem palace.  相似文献
