青海大通县出土汉代玻璃的研究

本文共对12件玻璃样品进行化学组成分析.其中,部分样品还进行了密度测定,X 射线衍射分析和显微镜观察.此外,还对一颗黄色玻璃珠的表面层进行 SEM-EDX 分析.结果表明,该玻璃珠表面有金箔涂层.根据分析结果,青海大通县出土玻璃的基础成分可归为三类,即铅钡玻璃(Na_2O-PbO-BaO-SiO_2系统玻璃),钠钙玻璃和钾硅玻璃(K_2O-SiO_2系统)。此外,还对玻璃的来源进行了探讨.     

古铜矿遗址围岩表层有害生物的防治

铜绿山古铜矿遗址地处长江中游地区、空气湿度大、围岩表层有害生物成片生长蔓延,对遗址的长期保护造成极大威胁。对此采取了改变遗址的环境条件、喷涂消杀药品的方法,消除了围岩表层有害生物的危害。经过一年半的观察表明该方法是可行的。

Chemical and Microscopic Study of Masonry Mortar in Ancient Pagodas in East China

Ancient mortars played a crucial role in the construction of historical architectures due to their physical and chemical compatibility with traditional building materials such as stones and bricks. Therefore, the analysis and optimization of the ancient mortar formula are significant in the restoration and preservation of historical sites. In this work, 20 mortar samples selected from five ancient stone pagodas in Zhejiang Province, China, were analyzed. The results showed that mud, lime-soil mortar, lime-sand mortar, and lime-gypsum mortar were used as binders in these pagodas. The Ca(OH)₂/aggregate ratio ranging from 0.3 to 2.7 was usually used to prepare lime mortar. Protein and polysaccharide were also found in some samples.     

Potential Use of Foamed Mortar (FM) for Thermal Upgrading of Chinese Traditional Hui-Style Residences

The Hui-style residence is an important architectural heritage of China. The hollow wall structures are widely used to build its exterior wall system. However, the thermal performance of the hollow wall is no longer able to meet the new energy-saving and environmental requirement. This article describes a laboratory study of the development of foamed mortar (FM), with the potential for use in thermal upgrading of the Hui-style hollow wall system without dramatically changing its traditional structure. The key early age, physical, mechanical and thermal properties were systematically measured. Two extended models were respectively developed to calculate compressive strength and thermal conductivity, as a function of porosity. Environment chamber test was also employed to investigate the effectiveness of this novel thermal upgrading approach and the results show that filling the voids with FM can effectively improve the overall thermal resistance of the hollow wall system by 44%, which is almost equal to the overall thermal resistance when using the more expensive commercial inorganic stucco system. In addition, the combination of these two methods yielded an overall thermal resistance of 0.701 m²·K/W, which is even higher than 0.67 m²·K/W for the code required in the hot summer/cold winter climate zone.

THE CULTURAL LANDSCAPE OF THE CHINESE BRONZE AGE

The Chinese Bronze Age culture from the 19^th to the 1^st century BC can be divided into four zones: the Central Plain in the middle and the lower Yellow River region; the Northern zone along the Great Wall; the Southern zone, south to the middle and the lower Yangzi River; the Southwestern zone covering the upper Yangzi River. In each zone, bronzes are not only different in types and styles but also function differently responding to the processes of the early state formation and social development. More precisely, in the first zone, there are mainly ritual bronzes, serving as symbols of the social and political hierarchy. In the second zone, there are mainly utilitarian items such as weapons, tools, bronzes of everyday use, ornaments, as well as horse‐chariot fittings. Bronze musical instruments characterise the third zone. And bronzes of the fourth zone are realistic or symbolic in style, depicting scenes of social life. Though having different cultural origins and characteristics, the four zones communicate with and influence each other continuously, creating a dynamic cultural landscape of the Chinese Bronze Age.     

Epipaleolithic/early Neolithic settlements at Qinghai Lake,western China

Transitions from terminal Pleistocene Upper Paleolithic foraging to Holocene Neolithic farming and pastoralist economic orientations in the northern Tibetan Plateau are examined from the perspective of Epipaleolithic sites located near Qinghai Lake, Qinghai Province, western China. Jiangxigou 2 is an artifact-rich, multicomponent midden site with the main period of occupation dating ca. 9000–5000 cal yr BP, containing abundant flaked stone artifacts including a substantial proportion of microlithic tools, abundant faunal remains including gazelle, deer, and sheep, and a small number of ceramics, including the oldest known on the Tibetan Plateau. Heimahe 3, on the other hand, is a brief hunter's camp dating ca. 8450 cal yr BP, with evident affinities to late Upper Paleolithic camps in the same region that date several thousand years older. The two distinctively different sites are probably nodes within a single Epipaleolithic foraging system that developed on the margins of the high Tibetan Plateau during the early Holocene, and that served as a basis for colonization of the high-altitude Plateau at that time. Jiangxigou 2 appears to be connected to early Neolithic agricultural settlements along the upper Yellow River (Huang He) drainage during the middle Holocene, and may provide insights into forager–agriculturalist interactions that lead to the development of pastoralist systems in the region.     

清代帝陵的哑巴院和月牙城

本文论述清代帝陵中的哑巴院和月牙城的建置与功用,进而探讨其规制的起源问题。指出关外的福陵与昭陵系参照北京明代后期的帝陵及清孝陵兴建,而南京明孝陵的规制已见哑巴院的雏形,其发展演变脉络清晰,故而哑巴院和月牙城并非明清两代帝陵规制最显著的差别。     

刘魁立先生访谈录

施爱东:做民间文化研究,许多人都把自己弄得很"田野",但我注意到您却非常注重仪表和礼节。只要是开会或上课,您总是西装革履地出现在公共场合,这样严谨地生活累不累?您参加我的博士后出站报告会的那一天,因为来不及回家换衣服,居然临时跑到商店买了一件正式的衣服换上了,那件事给我的印象非常深刻。
