During the Late Intermediate period (LIP, c. A.D. 1000–1400), the central Andes experienced the decline of the Wari and Tiwanaku states, as well as processes of state formation, regional population growth, and competition culminating in the imperial expansion of the Chimú and Inka polities. The LIP holds the potential to link the archaeological features of early Andean states with the material signatures of the later ones, providing a critical means of contextualizing the intergenerational continuities and breaks in state structures and imperial strategies. The recent proliferation of LIP research and the completion of a number of regional studies permit the overview of six LIP regions and the comparison of highland and lowland patterns of political and economic organization, social complexity, and group identity.  相似文献

烫样是研究清代皇家建筑的珍贵文物,为配合文物信息数字化工作的开展,针对烫样数据的采集和处理方法进行了深入研究。在综合考虑多种数据采集方法的特点及烫样数字化记录的难点后,选择使用手持式三维扫描仪与多视角三维重建技术相结合的方式来进行烫样的基础数据采集,并通过实践总结出了一套完整的数据采集和处理工作流程。与此同时,针对成果可能的应用方式做了些许尝试,且为数据的后期维护与进一步利用拟定了数据管理系统的建设方案。  相似文献

新华日报馆系全面抗战至解放战争初期中共中央在国统区设立的出版发行机构。本次工作以重庆红岩革命历史博物馆收藏的报馆出版物为研究对象和基础资料,以超景深三维显微系统、扫描电子显微镜、X射线能谱仪及pH测定仪对纤维构成、填料种类、造纸技术及纸张酸度进行检测分析。结合相关史料,发现报馆用纸受政治经济环境、造纸工艺、用纸策略影响,兼用机制纸和手工纸:早期(1938年1月11日《新华日报》创刊至同年10月24日)多用机制白报纸;中期(1938年10月25日报馆迁渝至抗战胜利前)渐用川渝改良土纸;晚期(抗战胜利后至1947年2月报馆被封闭)继用土纸。本研究可为新华日报馆出版物及同类文物的保护利用提供参考。  相似文献

近几十年来,我国考古工作曾先后在一些西汉遗址和墓葬中发现了若干纸状残片,于是引起国内外许多学和广大人民的关注和提出疑问。是否蔡伦前约二百年就有了纸?造纸术还是不是蔡伦发明的?新发掘的纸状物到底是个什么样?经对历次的发掘作了详细的调查研究和分析化验,结论认为:20世纪有关纸的考古发现不能否定蔡伦发明造纸术。  相似文献

为了解河南鹿邑太清宫长子口墓出土的部分典型玉器的材料属性与制作工艺,用多种无损科技分析技术对其进行了现场分析,获取了玉器材质矿物组成、纹饰微观形貌、穿孔孔径及内部微痕特征、表面琢磨微痕等综合物理化学信息。基于科技分析结果,确定了玉器的材质属性以及玉器表面纹饰、钻孔、琢磨等制作工艺相关信息。结合考古学背景资料信息,探讨了长子口墓地出土玉器在材质、器形、功能与工艺之间存在的关系。  相似文献

Through the assistance of trace element and petrographic analyses on 14 samples of mortar aggregates from Roman monuments, including the Porticus Aemilia, the Temple of Concordia, the Temple of the Dioscuri, Temple B and other structures of the Area Sacra di Largo Argentina, and the Villa di Livia, we establish the source area and we investigate the chronological employment of the volcanic materials used in ancient Rome's masonry. In contrast to previous inferences, the petrochemical data presented here show that systematic exploitation of the local ‘Pozzolane Rosse’ pyroclastic deposit has occurred since the early development of concrete masonry, at the beginning of the second century bc , through the early Imperial age. Subsequently, exploitation was extended to the overlying Pozzolane Nere and Pozzolanelle deposits. Only during the early phase of development of the concrete masonry in Rome, volcaniclastic sediments outcropping near the construction sites were mixed with the sieved remains of the tuff employed as the coarse aggregate, to produce the fine aggregate. The results of the study on the investigated monuments suggest the possibility of establishing the chronological identification of three different types of mortars, as a function of the composition of the volcanic material employed in the fine aggregate, which, when implemented by future studies, may contribute to the dating of monuments and archaeological structures.  相似文献

The 2013 Australian Defence White Paper categorically termed Australia's zone of strategic interest the Indo-Pacific, the first time any government has defined its region this way. This raises questions about what the Indo-Pacific means, whether it is a coherent strategic system, the provenance of the concept and its implications for Asian security as well as Australian policy. Indo-Pacific Asia can best be understood as an expansive definition of a maritime super-region centred on South-East Asia, arising principally from the emergence of China and India as outward-looking trading states and strategic actors. It is a strategic system insofar as it involves the intersecting interests of key powers such as China, India and the USA, although the Indo-Pacific subregions will retain their own dynamics too. It suits Australia's two-ocean geography and expanding links with Asia, including India. The concept is, however, not limited to an Australian perspective and increasingly reflects US, Indian, Japanese and Indonesian ways of seeing the region. It also reflects China's expanding interests in the Indian Ocean, suggesting that the Chinese debate may shift towards partial acceptance of Indo-Pacific constructs alongside Asia-Pacific and East Asian ones, despite suspicions about its association with the US rebalance to Asia. Questions about Australia's ability to implement an effective Indo-Pacific strategy must account for force posture, alliance ties and defence diplomacy, as well as constraints on force structure and spending.  相似文献

Bitumen, found in abundance in Mesoamerica’s southern Gulf Coast region in natural seeps and in many archeological contexts, is an important economic resource and exchange item that has received little consideration in Mesoamerica. Analyses of archeological, ethnoarcheological, and experimental data provide insights on the organization of bitumen processing activities, and the end product (archeological bitumen), which the Olmec (1200–400 BC) used in the production of many items. Archeological data are derived from investigations at El Remolino and Paso los Ortices— two Early Formative period levee sites in the San Lorenzo Olmec region. Our findings suggest that among the Olmec, bitumen processing was organized as a specialized activity, involving multiple production stages, but not necessarily elite involvement or control.  相似文献

Ongoing excavations at Olduvai Gorge, Tanzania, reveal tremendous variability among stone artifact assemblages across the Plio-Pleistocene Olduvai Lake Basin during Bed I and lower Bed II times. Theoretically, stone artifact traces of Oldowan hominin land use are determined by the distribution of larger mammal carcasses and arboreal refuge from predation as well as proximity to stone material sources.  相似文献
