国外进口瓷器修复专用材料的应用研究

国内外瓷器修复的基本流程没有很大差异,但是西方国家生产的修复专用材料品种较丰富,值得国内修复界吸收与应用。为此,本研究着重对Hxtal NYL-1、Golden Porcelain Restoration Glaze、Golden Polymer Varnish with UVLS三款瓷器修复专用产品开展分析研究。测试结果显示,在国内外5类环氧树脂中,Hxtal NYL-1的拉伸强度最低,断裂伸长率最高。Hxtal NYL-1在波长365nm的紫外线照射78d后,其色差变化最平稳。紫外可见光谱数据显示Golden Glaze仅吸收一定的中波紫外线UVB,Golden Varnish对长波紫外线UVA和中波紫外线UVB都具有吸收能力。波长365nm紫外老化实验可证明Golden Glaze和Golden Varnish都具备较好的光稳定性。而在254nm紫外老化环境下,Golden Varnish表现出更佳的抗紫外性能。此外,围绕瓷器修复实例,对这些产品的在修复中的使用方法进行了简要梳理。     

五代北宋高邮秦氏家族世系研究——以江苏扬州发现秦咏夫妇墓志为线索

扬州发现两合石质墓志,其主人北宋秦咏及其夫人朱氏,应系北宋著名文士秦观之祖父母。秦氏祖茔江都西山,即今西湖镇蜀岗村吕庄组七仙墩一带。通过对历史文献资料的梳理,可以对秦氏家族世系展开进一步考察,纠正秦氏家族部分成员在古代文献流传过程中出现的错误名讳记载,部分成员应因避讳等原因存在更改名字的现象;还可厘清包括秦咏及孙男秦观在内的秦氏十代家族世系,以及主要成员的生平事迹。     

《里耶秦简》(壹)所见作徒管理问题探讨

秦代编制作徒簿的机构有授予方的司空和仓,但二者分工不同;接收方包括库、田官、畜官、少内、属乡等。作徒簿分为临时付受与月度统计两种。秦代各级地方机构对刑徒管理的分工为:郡提出指导原则,县掌握本县刑徒的数据,县属机构负责具体管理。在当时人的观念中,徒隶是一个阶层的泛称,但在司法行政文书中则有特定的内涵,司寇不包括在内。     

《米巫祭酒張普題字》補釋

《隸續》載《米巫祭酒張普題字》全文,宋洪适對碑文作了綜述,云:"此碑有天師道法及祭酒、鬼兵字,而云受《■經》十二卷,蓋諸張妖黨指傳授之約,頗合史氏所載。"本文對"張普題字"以及該碑所在地作了分析。傳授之約或是祭酒向初入教的道徒傳授道家關於宇宙原始以及長生之道的基本觀念。此碑實是現存罕見的爲後人留下史籍未備的五斗米道入道儀式記録。     

Pray the gay away: identity conflict between Christianity and sexuality in Hong Kong sexual minorities

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.     

Crowdsourcing Model Research for the Identification of Post-Earthquake Rescue Objects

The quick and accurate identification of post-earthquake rescue objects can minimize the casualties and property loss caused by earthquakes. With the rapid development of remote sensing technology, rescue objects can be identified through high-resolution remote sensing images. There are two main categories of approaches to identify rescue object through high-resolution images: automatic extraction by a computer and visual judgment by professionals. Although results can be obtained quickly by using automatic extraction, the accuracy of the results is unacceptably low. For visual judgment, the large demands for time and professionals restrict its wide practical application. In this study, we introduce crowdsourcing into the identification of post-earthquake rescue objects. First, we integrate the advantages of the computer and crowdsourcing, which means that the computer takes advantage of the speed of information processing, while crowdsourcing makes full use of human recognition capabilities. Second, we take visual judgment tasks out of the hands of professionals and entrust the tasks to workers in a crowdsourcing platform. Not only are the human resources infinite, but we can also improve the efficiency of identifying rescue objects. Third, we propose a crowdsourcing model that improves the quality of the results and saves human resources. Finally, experimental results demonstrate that our solution is feasible.     

秦兵马俑和汉阳陵遗址保存环境之比较

为了探索一种适宜的遗址文物保存方式,在四季分明,气候变化较为剧烈的西北地区的文物遗址环境区,达到最大程度保护遗址文物的目的,通过对开放式的秦始皇兵马俑博物馆一号坑遗址环境的建筑结构、温度和相对湿度变化及大气颗粒物进行分析监测,并与封闭式汉阳陵博物馆外葬坑的结果进行对比研究,发现单从环境温湿度恒定、阻挡室外颗粒污染物和气态污染物的角度来讲,封闭式的汉阳陵博物馆存在明显的优势。但依然不能阻止温湿度的季节间波动和室外空气污染物渗入的威胁,同时还要预防室内污染的发生,并且出现玻璃护围内部结露,文物大面积返碱等问题,并不能很好解决文物良好保存和观展目的。所以依旧需要探索一种适宜的遗址文物保存方式,既能保持文物保存环境的温湿度的相对稳定和洁净,又能缓解全封闭玻璃护围内部结露,文物大面积返碱等问题,最大程度延长遗址文物的寿命的同时,满足观众参观的需求。本对比研究结果可为今后的设计提供参考。     

Ruling the Land of the Yellow Lama: Religion,Muli, and geopolitics in the 17th century Sino-Tibetan borderland

Abstract

The author scrutinizes the history of Muli (木里) as a semiautonomous political entity in the 17th century southern Sino-Tibetan borderland. By tracing Muli’s improvization in the face of multiple powerful regimes such as the Naxi kingdom, the Geluk Tibetans, the Khoshut Mongols, and the Chinese dynasties, the author explores how an indigenous notion of power took shape in the wake of geopolitical turbulence. Before 1580, Muli was a colony of the Naxi kingdom and dominated by the Kagyu school of Tibetan Buddhism. After 1640, it became a stronghold of the Tibetan Buddhist Geluk school and was deeply involved in the power struggles between the Geluk and Kakyu schools as well as the Tibetans and Mongols. Despite of acknowledging multiple sovereigns, Muli rulers utilized various tactics to hold on to power and prioritize local interest. The nuanced, yet creative, strategies Muli people adopted showcases the significant role border regimes played and their agency in shaping the power dynamics in pre-modern Eastern Asian borderlands.     

What can pollen grains from the Terracotta Army tell us?

The provenance of more than 2200-year-old terracotta warriors and horses in the Qin Shihuang Mausoleum is still a mystery, even though some researchers have inferred that the terracotta figures were produced near the mausoleum. The sporomorphs (pollen and spores) extracted from terracotta fragments of a warrior and a horse and compared with those obtained from soil samples from the Qin Dynasty layer in Pit No. 2 of the Qin Shihuang Mausoleum indicate that the pollen spectrum from the terracotta horse is different from that of the warrior, but similar to the local soil samples. Herbaceous pollen was dominant in the warrior sample, while arboreal pollen predominates in the horse and soil samples. Palynological evidence suggests that the terracotta horses were produced at a locality near the mausoleum, while the warrior came from a site which was further afield.
