Elemental Characterization by EDXRF of Imperial Longquan Celadon Porcelain Excavated from Fengdongyan Kiln,Dayao County

A mass of Longquan porcelain shards carved with ‘Guan’ or the dragon patterns were unearthed in the early Ming Dynasty layer of the Fengdongyan kiln site at Dayao County. These celadon shards were fired in the Hongwu and Yongle eras of the Ming Dynasty. In order to research the raw materials and firing technology of the imperial porcelain, 85 typical shards were analysed by energy‐dispersive X‐ray fluorescence (EDXRF). The results indicate that the contents of TiO₂ and Fe₂O₃ in the body vary in the Hongwu and Yongle eras. Compared with Longquan glazes in the Southern Song Dynasty, the average values of K₂O, Fe₂O₃ and TiO₂ are higher, but that of CaO is lower in early Ming imperial porcelain glazes. Principal components analysis (PCA) shows that different degrees of elutriation of the same raw materials are the main reason for this difference in the Hongwu and Yongle periods. However, the raw materials of imperial porcelain glazes show no obvious changes and have inherited the earlier tradition. The production and firing technology of imperial porcelain reached a higher level and had not declined in the Early Ming Dynasty.     

一件紫檀嵌粉彩瓷片椅的修复研究

在故宫博物院的藏品中,有12把形制相同且用材和工艺极具特点的清宫旧家具——紫檀嵌瓷片椅,作者在认识其材质、用途以及镶嵌、藤编、粉彩画等工艺的基础上,分析了椅子的伤况及其成因,并依据最小干预原则制订了修复方案,解决了椅子劈裂、开粘、断裂、变形等问题。本文即是对该椅修复过程所作的科学记录,并通过经验总结对古代家具的保存与保养提出了建议。     

Neighbourhood food environments revisited: When food deserts meet food swamps

This study uses service area–based coverage and various count regression methods to assess neighbourhood-level healthy and unhealthy food environments, and food access associated with different socio-economic groups in Edmonton, Canada. We identify three types of vulnerable neighbourhoods according to different food environments: food deserts (i.e., neighbourhoods lack sufficient access to healthy foods); food swamps (i.e., neighbourhoods have excess access to unhealthy foods); and those with overlaps of food swamps and food deserts. We also identify neighbourhoods with superior access to healthy foods (i.e., food oases). Additionally, our results from regression analyses indicate: (1) child population is negatively associated with both healthy and unhealthy food resources; (2) good access to public transportation is associated with good coverage of all healthy food outlets and convenience stores; and (3) deprived neighbourhoods with higher percentages of minority populations have better coverage of both healthy and unhealthy foods in general. The results from this study can help the City of Edmonton identify the key neighbourhoods with high potential for local business and the hotspot neighbourhoods that require particular support. Tailored strategies are proposed to effectively and efficiently improve food environments with limited resources.     

吴梅致王立承论曲书札五通笺释

吴梅、王立承皆为戏曲文献收藏大家,其藏品既多且精。国家图书馆藏吴梅致王立承书札五通,于两家所藏戏曲珍本讨论尤多。彼时吴梅刚刚返回南方,在东南大学任教。二人书札南北往还,涉及戏曲文献的评价、收藏之处颇多,可见当时戏曲文献收集之情形,对民国戏曲史研究有重要价值。本文于其关涉戏曲版本之处,略为疏释,于其间戏曲版本相关讨论,或纠其误,或补其缺,并梳理其收藏源流。     

20世纪30年代日本对我国南沙群岛政策的演变

20世纪30年代,日本对我国南沙群岛政策呈现出阶段性变化。1933年“九小岛事件”发生之际,日本在对外政策中坚持“协调外交”路线,与法国达成妥协,实现共存。1936年当“南进”政策成为日本的国策时,向我国南沙群岛的扩张成为日本实施向外南洋扩张计划中的一部分。随着日本军部逐渐主导国家对外决策及国际局势的新变化,日本外务省从极力反对海军省的行动演变为积极献策,一致主张驱逐法国势力,武力侵占我国南沙群岛。1939年3月末,日本将我国南沙群岛非法“编入”领土。20世纪30年代日本对我国南沙群岛政策演变是日本外务省、海军省基于国内政治与国际时局综合考量,也是他们分歧、折冲、平衡的结果。     

曹仲达与“曹家样”研究

本文重新研究曹仲达与“曹家样”,考订了曹氏的生卒年及其可考的生平,认为他有着由南(朝)入北(朝)的经历。本文从画史所载曹氏师承入手,发现代表南梁新画风的张僧繇和来自中亚西域的塞特(壮)勤是其师承的重要来源,从而进一步探讨了“曹家样”的形成问题,认为“曹家样”是南、北二源以及其他复杂的社会、宗教、文化身份认同等因素共同作用的结果。本文还对长时段、大范围内相关的图像遗存进行考察,重新勾勒了“曹家样”的面貌。在对这一具体问题研究的基础上,作者提倡在后现代之后风格史研究的一种可能与方向——厚背景研究法。     

为《明万历四十七年〈会试中式题名〉》续貂

<文献>2002年第4期刊载了周绍良先生的大作<明万历四十七年〈会试中式题名〉>,以前由于未涉足相关领域的研究,故对此文,笔者只是略读而已.近两年来,笔者有幸参加龚延明师主持的<中国历代登科总录>大课题组,对明代科举制度有了一些肤浅的认识,并对相关的原始文献和研究论著进行了收集.此时,重读周先生的大作,才真正认识到其价值所在.文章不但介绍了一般读者所不易知的会试录、登科录等珍贵文献的体例,还特别公布了一种世所罕见的科举录--万历四十七年<会试中式题名>,这是一个填补空白的发现.     

六胡州古城址的发现及其环境意义

本文在追溯唐代六胡州的建置与“灵、夏之间”行政沿革的基础上,通过对内蒙古、宁夏、陕西三省区交界处,即毛乌素沙地西南缘的实地考察,并依据考古与文献资料,初步确定了今鄂托克前旗与盐池县境内的六个唐代古城址与六胡州的对应关系。从古城址的时空分布格局、选址条件、人类活动方式等出发,阐述了六胡州古城址的环境指示意义。唐初六胡州北部已经有比较严重的土地沙漠化问题,而六胡州一带建城时因受早期沙漠化过程的影响,在局部地形部位可能分布有地表积沙。     

从湖南的地方志看湖南资本主义萌芽产生的历史前提

明清之际的湖南已经具备了资本主义萌芽产生的历史前提。这主要表现在：湖南农业生产力有了一定程度的发展,耕田面积扩大了,耕作技术提高了,粮食生产有了剩余,农业生产内部分工显著;手工业和矿业逐渐成为独立的生产部门,社会分工有一定程度的发展;商业和商人资本因为基本生产部门的发展而具有了一定的规模。     

黑水靺鞨思慕部探索

本文反对唐代“黑水”是指穆棱河与乌苏里江及其支流的观点,认为黑水是指黑龙江中下游段。结雅河下游发现的考古遗迹族属是黑水靺鞨之思慕部,不是从松花江迁移到结雅河下游流域的粟末靺鞨。靺鞨思慕部文化具有草原文化的成分。靺鞨族人种是复杂的、多源的。思慕部墓葬人骨得出的人种类型只能代表思慕部,能否代表黑水人种,或代表全体靺鞨人种,还需要新的对比材料。
