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

This technical note presents a refined technique for photo‐documenting archaeological mortuary features using High Dynamic Range (HDR) imaging. Mortuary features in archaeological context can be complex and delicate given the wide variability in grave constructions and preservation of human skeletal remains. It is therefore critical to obtain the greatest detail possible when photo‐documenting these features. HDR techniques represent more contrast in photographs and provide greater detail across the DR of illumination within mortuary features—where complex arrangements of human remains can obscure or darken other elements or associated funerary objects, making them difficult to identify in traditional photographs. HDR can be employed with most standard digital single lens reflex cameras used for archaeological field projects, is easy to learn and employ (as described here), can be processed and produced with commonly used photo editing programs, and is ideal for use in unpredictable conditions that are often encountered with archaeological mortuary features and in field conditions.

We examine the relationship between gender of the barrister and appeal outcomes on the High Court of Australia. We find that an appellant represented in oral argument by a female barrister, opposed to a respondent represented in oral argument by a male barrister, is less likely to receive a High Court justice's vote. However, we also find that the appellant disadvantage of having a female barrister present oral argument is (partially) offset in the case of liberal justices and on panels having a higher proportion of female justices. The extent to which the disadvantage is offset, and potentially turns from being a disadvantage to an advantage, depends on the degree to which the justice is liberal and the proportion of female justices on the panel.

本文探讨律师性别与诉讼结果之间的关系。我们发现这个过程并不对称。如果是由女律师上诉,而辩方是一个或一个以上男性律师,那么性别就是一个因素。不过并不存在相反的情况。我们具体发现,如果诉方是一个女律师,辩方为一男律师,诉方就不大可能获得最高法官的赞同。不过,我们还发现,如果法官具有自由主义精神,如果法官团的女性比例较高,那么女律师的不利情形就有可能被(部分地)抵消。被抵消的程度取决于法官自由精神的强弱,和法官团女性比例的大小。  相似文献

The bodies and glazes of 27 early Western Zhou proto‐porcelain samples from Yejiashan cemetery, Hubei Province, were analysed using LA‐ICP–AES, SEM, XRD, a thermal expansion instrument and other analytical methods. The results indicated that the bodies of all samples were characterized by high silicon and low aluminium, and were made with porcelain stone raw materials found in the south of China. The glazes are typical of high‐temperature calcium glazes of the CaO (MgO) – K2O (Na2O) – Al2O3 – SiO2 series, with relatively high Mn and P content, which was probably caused by the addition of plant ashes. The physical properties and phase compositions of Yejiashan proto‐porcelain show that firing processes were still in the early stages of development in ancient China. Multivariate statistical analyses indicated that Yejiashan proto‐porcelain might have come from the Deqing area, in Zhejiang Province. These results provide new archaeological evidence for research on issues related to material flow in the Western Zhou dynasty.  相似文献

A large systematic dye investigation of prehistoric Danish and Norwegian bog textiles was carried out using high performance liquid chromatography with photo diode array detection. After the selection of the most suitable protocol for dye extraction and HPLC analysis for this specific group of archaeological samples, the second part included the characterisation of the dyes detected in the whole series of the Early Iron Age textiles and the interpretation of the dyeing technology. Natural organic dyes were found from the three main categories of natural dyes, hence throwing new light on the use of biological dye sources in Early Iron Age Scandinavia. The results clearly indicate that most Scandinavian peat bog textiles originally were dyed and that already during the 1st millennium BC, the populations in Scandinavia were familiar with the dyeing technology.  相似文献

This paper considers Frobisher Bay and Inuvik, two Canadian Arctic towns, as examples of the high-modernist planning that swept the globe during the middle decades of the twentieth century, but also Cold War projects reflecting a sudden interest in the Arctic as a region of military significance. Building on the framework provided by James Scott in Seeing like a State (1998), the paper details the connections between modernization theory and Cold War militarism before turning to the strikingly parallel case studies. In each instance, federal officials proposed ambitious urban models designed to simultaneously overcome the hostility of a northern environment and catapult native northerners into conditions of modern living. While the limits and failings of such schemes varied by location, both sites were also laboratories for social scientists employed by the federal government to document and analyze the modernization of the Arctic. The work of these scholars represents a particularly rich and complex record of governmental interventions, tied variously to Cold War imperatives, in northern lives and landscapes at a time of great faith in the transformative power of modern engineering.  相似文献
