为了预防性保护和修复秦俑,必须掌握秦俑残片显微结构及其烧制环境、破损方式,从而为改善秦俑修复工艺、筛选修复材料提供基础,运用偏光显微镜对秦兵马俑残片中的一些矿物质(石英、长石、云母等)颗粒的分布形态和含量来分析陶土的成分结构、制作工艺、烧成气氛及原料来源等信息。结果表明,秦俑陶片主要成分为少量砂屑及大量粘土,而粘土为岩土矿风化的产物,秦俑残片裂痕较多的部位风化、酥粉痕迹明显。秦俑制作工艺以模为主,模、塑结合,并在粘土中添加了细砂,多于还原气氛中烧制而成。  相似文献

对中国人种起源的探讨,是20世纪上半期广泛关注的话题,经历了一个从"西来说"到"土著说"的过程.这一转变,考古发现是个重要原因,但其中蕴含了一点民族情感,二者共同促成了"土著说"的确立.从民族主义立场来看,"西来说"与"土著说"是一脉相承的,都是建构民族认同的努力.在中国近代民族危机中出现的民族溯源,其发生与变化反映了20世纪上半期中国民族主义的曲折发展.  相似文献

Although much is known about broad trends in Australian Indigenous geographies, particular aspects of Indigenous spatiality continue to be rendered invisible by standard statistical measures. The national census, for example, only registers moves at one and five year intervals. Any mobilities enacted within these timeframes are not measured. Yet these statistically ‘un‐captured’ mobility processes are often integral to Indigenous lived experiences and have a significant dialectical relationship to government service delivery processes. Understanding these population dynamics is therefore a critical, though underdeveloped, consideration within geographic enquiry and contemporary debates about State and Federal Indigenous policy directions and initiatives. This paper presents qualitative research findings regarding local experiences and perceptions of Indigenous spatiality in Yamatji country, Western Australia. Within this grounded framework, the paper builds on existing literature by drawing out some of the common spatial, temporal and demographic characteristics, or dimensions, of statistically un‐captured Indigenous mobility processes. With this discursive, albeit generalised and malleable, typology established, the analysis turns to a reflection on some of the methodological and conceptual complexities of measurement, interpretation, and translation of these mobility processes across the policy‐research nexus.  相似文献

We explore bone microstructure for taxonomic identification of archaeological bones too fragmentary to permit secure identification on morphological grounds. Backscattered electron (BSE) imaging is used to observe bone tissue types and the arrangement of vascular canals, and to facilitate quantification of osteonal canal dimensions. Examination of known examples of relevant taxa (humans [n = 8], pigs [n = 4] and dogs [n = 4]) shows significant differences among them. When the results of this examination are applied to a blind test of modern and archaeological specimens (humans [n = 8], pigs [n = 2]), 100% of specimens are identified correctly. The approach is applied to 13 morphologically unidentifiable fragments from Hawai’i and Fiji to evaluate its potential for identifying bone tools and to increase the number of samples available for dietary analysis. Potential applications of the approach for other contexts are discussed.  相似文献

Chickens were part of the Lapita cultural complex, transported into and through the Pacific by prehistoric colonists; as such they can be used as a proxy for tracking prehistoric migration and interaction. The Lapita site of Teouma in Vanuatu is well known for the recovery of complete dentate stamped pots and a cemetery containing the largest collection of Lapita period skeletons ever found. Chicken bones recovered from these excavations provide the first ancient DNA sequences from any commensal organism directly associated with a Lapita context. The ancient mtDNA sequences obtained from two Teouma chicken bones are compared with previously published archaeologically derived ancient DNA sequences to extend our understanding of the spread of chickens in Pacific prehistory. The results also show that the haplogroup E signature was present in very early populations of chickens transported into Remote Oceania. This study also adds to the suite of available data relating to isotopic signatures for commensal animals during the early settlement of Vanuatu and may reveal a different diet for Teouma chickens than those from other early prehistoric assemblages in the Pacific.  相似文献

如今我们已经能够正确解释甲骨文中的大多数辞例。对于一些迄今理解尚有分歧的疑难辞例,应尽可能地通过同版或同文关系,甚至其他卜同事的关系,来思考这些疑难辞例的辞意。若卜辞辞意难以推知,可以暂从语法学等角度对卜辞中的某些疑难字作词性上的定位。  相似文献

The paper reports a case study of factors attracting and retaining talented and creative workers in Halifax, Nova Scotia. All categories of workers interviewed mentioned quality of place and amenities in discussing their location preferences, but that could not fully explain their choices. For some occupations (like health research), talented people followed jobs; in other sectors (like music), talented workers migrated to a sympathetic locale with the right conditions for creative engagement; creative workers in some occupations (like those in architectural, engineering or planning consulting) were more rooted in place. The social dynamics—that is, positive and collaborative social networks within key sectors and a wider community perceived as welcoming and interesting—make this mid‐sized city attractive to talented workers. Local universities and a vibrant music scene generate a mutually reinforcing context that attracted mobile talented and creative workers to the city. Respondents noted Halifax's limited cultural diversity but did not report a perceived lack of tolerance as affecting their choices. In smaller cities, the social dynamics of place and workplace and the quality of life available may play more significant roles than tolerance in attracting and retaining talented workers, challenging a basic assumption of creative cities discourse.  相似文献
