The selection of a non-shattering phenotype is a pivotal change in the process of rice domestication. However, current research is heavily restricted by the preservation conditions of macro-plant remains in early and middle Neolithic sites, as very limited well-preserved rice spikelet bases could be retrieved. We present a non-destructive method based on micro-computed tomographic (CT) scanning, which could provide detailed visualization of the internal structures of charred spikelet bases and efficiently discriminate the shattering and non-shattering phenotypes of rice spikelet bases according to the abundance of fusiform echinate phytoliths. It could be widely applied in different contexts, especially those poorly preserved specimens and tempers in pottery sherds, greatly improving our knowledge of rice domestication.  相似文献

广西桂平博物馆藏东汉铜甑对于研究广西地区青铜器冶铸技术的发展具有重要的研究价值。但器物长期保存于潮湿环境中,矿化严重、保存状况较差,亟须保护修复。本研究应用X射线影像观察、金相显微镜、扫描电镜及能谱分析、模拟实验验证等方法研究了器物的铸造工艺、合金成分以及锈蚀产物成分。结果表明该器物为整体铸造成形,器物铸造时使用了轮制技术、刮板造型工艺以及铸后刻纹的工艺,箅部范块制作过程是用器身模翻制器身范后脱模,将器身模的圈足部分切下,然后在圈足泥模上刻出箅部型腔。在此基础上,遵循最低限度干预原则,力求将传统的文物修复手段与现代修复理念相结合,通过除锈、修补等保护修复措施后,不但提高了器物的整体稳定性,而且达到了可以展陈,发掘文物潜在价值的要求。  相似文献

布赖德威尔(感化院)在英国社会转型进程中发挥了重要作用。英国布赖德威尔体系的形成经历了城市试验与国家推广两个阶段,是地方创造力与中央意志力合力的结果。布赖德威尔具有公共雇佣和规训惩罚等多重功能。围绕功能的定位,布赖德威尔的性质有一个从雇佣机构向规训机构的明显变迁,这反映出理想与现实之间的纠结和平衡。  相似文献

Recognition and respect for sexual minorities in Hong Kong is still a contested area. Public sexual identity politics in Hong Kong has been framed by traditional Chinese gender ideology and imported Christian beliefs which are profoundly negative. Focusing on the interpersonal relationships in three spheres of life, the research adopted the sociological perspective of personal life and the feminist geographers’ idea of spatialization of identity management to analyze how the sexual self of sexual minorities has been marginalized and excluded in intimate social spaces of family, church communities and schools in Hong Kong with specific spatial practices and different forms of power/knowledge. By examining overlooked intimate injustice in personal life, this study illustrates that identity conflicts between Christianity and non-heterosexuality in everyday life is constructed through misrepresentation, misrecognition, harassment and exclusion in intimate relationships. Different types of knowledge are being used to reiterate pre-existing norms and institutionalized patterns of cultural value that constitute the sexual minorities as comparatively unworthy of respect. These micro-political processes involve both conformity and resistance to gender and sexual stereotypes. Participants managed to develop spatial coping strategies such as concealment, compartmentalization, confrontation and alternative sources of support to manage their lives with dignity and self-esteem.  相似文献

An earthquake of moment magnitude Mw 7.8 struck Nepal at 06:11 UTC on April 25, 2015. Field reconnaissance focused on the geotechnical engineering aspect of the earthquake was carried out in the Kathmandu Valley and regions near the epicenter. This paper presents briefly the geology of Nepal, the accelerogram, and results of standard penetration tests at selected sites in the valley. The study shows the failure case histories including landslides, road embankment settlement, bridge foundations and abutment damage, and liquefaction. The paper also highlights the impact of local soil properties and basin and ridge effect on the severity of damage.  相似文献

The oldest extant musical instruments in the world are stone chimes. This music was created by the ‘eight tones’ that could be produced by these ‘stone’ voices. Although many of these stone chimes have been unearthed from sites predating the Spring and Autumn Period and the Warring States Period in China, their discussion in archaeological reports is usually not very thorough. In this paper, the ancient and modern samples are analysed from the point of view of lithology. The aim is to explore how the ancients chose to make these stones, and to check that the type of stone from which these ancient Chinese stone chimes are made is actually those recorded in previous studies. The results show that most of the ancient stone chimes in China are made of limestone. These chimes required a material with a single, homogeneous and compact mineral composition. Lingbi chimes (a kind of ‘lithophone’ produced in Lingbi county, China, are pure in composition and have a fine microcrystalline structure, which is the best choice for making stone chimes. This paper makes a systematic study of the lithology of Chinese stone chimes. The results supplement a significant lacuna in the study of ‘lithophone’ and ancient stone instruments both in China and on a more global scale.  相似文献

近代中国具有现代意义的投票选举制度虽然率先在清末的民间工商社团商会中实行,但各地商会的具体实施过程却并非同步进行。上海、苏州等商会正式成立后即开始制订并实行这一制度,天津商会则在清末坚持采用"公推"的方式推举总理、协理和会董,没有真正实施"票举"。到民国初期,天津商会依然认为"公推"优于"票举",直至明定商会必须实行投票选举制度的《商会法》公布之后,天津商会还希望政府"准予特殊办法,仍行公推"。但实施"票举"在当时已是大势所趋,1918年天津商会也在章程中拟订了投票选举制度,并由此进入"票举"会长和会董的新时期。自清末至民国时期天津商会从"公推"到"票举"的曲折演进历程,说明在选举制度的建设中,天津商会的领导人在思想认识和实践操作两个方面都偏向于保守,不仅自身缺乏创造性的举措,而且很少主动借鉴和学习其他商会已有的投票选举制度,这种现象也表明了清末民初各地商会对现代投票选举制度的认识并不完全一致。  相似文献

良渚遗址是实证中华5000年文明史的遗产地,良渚玉器在专业领域也一直受到广泛关注,2019年7月,良渚古城遗址项目成功列入《世界遗产名录》,更是让良渚文化走入了大众视野。7月16日,"良渚与古代中国--玉器显示的五千年文明展"在故宫博物院武英殿开幕。为了配合这一专题展览,中国文物学会玉器专业委员会、故宫研究院玉文化研究所、杭州良渚遗址管委会及良渚博物院联合主办了"良渚玉文化论坛",于8月30日在故宫博物院兆祥所召开,来自中国大陆及台湾地区的60余位代表出席了论坛,其中6位代表进行了主旨发言,学者们就出土与传世良渚玉器的相关问题展开了讨论。以下从这两方面分别加以概述。  相似文献

前秦时关中氐人分布的武都是指侨置武都郡。侨置武都郡始于曹魏。曹魏为与蜀汉争夺陇右,将武都氐人迁徙至关中,并先后在小槐里和美阳设置武都郡以进行管理。西晋江统的《徙戎论》反映出此时关中武都氐聚居的地方未置武都郡。十六国初期屠各刘氏和羯族石氏先后统治关中,将大量氐羌迁往关东,因此这一时期在关中侨置武都郡缺乏现实基础。苻健立国关中后,在战略要地宝鸡附近侨置武都郡,是其氐人本位政策的体现。北魏时侨置武都郡始领县级行政单位,统治范围扩大,标志着氐人的关中化,同时它也是太武帝平定盖吴叛乱时分化关中南道氐人的重要战略举措。西魏北周立国关中后受政区滥置影响,武都郡领县减少。隋开皇间侨置武都郡在当权者废郡、保留州县的地方行政政策的影响下消失于历史舞台。  相似文献
