试论舟形灶

汉晋墓出土的舟形陶灶分布较广,以淮河及长江下游的江浙皖赣地区为中心,广泛见于北至鲁南,西到湘鄂西部,东南至海的广大区域.其延续时间较长,有些类型一直沿用到宋代.各种类型的舟形灶均有特定的分布区域,随着时代的推移,逐渐向外传播,其中最为典型的B型和C型舟形灶,南移趋势明显,这与历史上的人口南迁有较大关系;而具有岭南文化因素的D型灶则向附近的江西和福建扩散.江淮之间的苏皖地区出现了A型、B型和C型舟形灶的较早类型,不排除这里是舟形灶发源地的可能.     

A Gravity Model with Variable Coefficients: The EEC Trade with Third Countries

Gravity models with fixed coefficients have been used to explain the trade flows between countries different in income levels and separated by long distances. It is unrealistic to assume that these models can hold with the same parameters across very heterogeneous countries. This paper proposes and estimates an international trade model with variable coefficients constructed by combining Pöy-hönen's and Linnemann's gravity-based trade models via the expansion method.     

日本侵华战争时期女明星的形象建构——以李香兰为例

日本侵华战争时期,中日两国人民除了蒙受战争苦难之外,还在不同程度上遇到国族与文化认同等问题,女明星也不例外。身为日本人的李香兰,在舞台上往往是以中国人的形象或主体身份示人,并闪现星光。然而,日本侵华当局的幕后掌控,民族意识的萌生,性别的纠缠,使她在战争的特殊环境里处于矛盾、挣扎之中,艰难地做出国族的选择和认同。在多种力量的交互作用下,最终完成了第二次中日战争时期女明星李香兰的形象建构,其中也包含着李香兰个人的主观想象和抉择。不容否认的是,战争时期建构的女明星形象在一定程度上影响着李香兰战后的行为。然而随着局势的不断变化,和平与发展成为国际潮流,李香兰在社会大舞台上扮演了新的角色,并树立起新的社会形象,赋予日本侵华战争时期女明星以新的内涵。

正It is just the dawn,but the sheepfolds have already begun to move restlessly.Sunlight makes its way in.Tashi Tsedan and Redan open the sheepfolds one after another.Flocks of sheep suddenly gush out like an influx of water from an opened gate.These two herdsmen from Jirong Village in Drik Town of Gampa County are fulfilling their duty grazing these flocks of Gampa sheep,a well-known breed of Tibetan sheep.     

旅游体验质量评价述评:研究进展、要素解读与展望

旅游体验是游客情感价值的累积。旅游体验质量评价是对游客心理累积情感的测度,科学、准确的核算游客体验质量是旅游景区、旅游企业等可持续发展及竞争力提升的重要保障。本文通过对1980-2015年发表于国内外旅游及管理领域重要期刊文献的梳理,从服务质量研究的历史、科学视角及与旅游融合的角度对旅游体验质量评价的研究进展、理论基础等进行系统的回顾,并从体验质量评价的理论视角、思路、特征、类型与准确性、可操作性、应用范围等中观层面,对所梳理出的4类国外主流质量评价范式进行旅游体验哲学视角下的解读、比较分析和总评,最后对该领域未来研究重点进行展望。     

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.     

AN ECOLOGICAL SAFETY SHELTER ESTABLISHED ON THE SNOWY HIGHLAND

<正>On the snowy highland,the splendid view of mountains and waters vie with each other;the birds and beasts stroll idly as in a courtyard,and the flourishing woods and grasses stretch as far as the eyes can see.Is"Shambhala"a fairyland?Over the years,the central government and Tibet have focused on protecting the highland ecology and have attained impressive achievements.Under the blue sky     

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.     

《女界钟》:解读国民革命思想中性别意识的重要文本

中国近代历史上的第一部系统介绍女权思想的著作《女界钟》,首次比较系统地提出了女性参政的思想。《女界钟》批驳了女性不宜参政的生理差异决定论,并从女性参政权与女权、女性参政权与国民革命两个方面讨论了女性如何参政的问题。诞生于辛亥革命前的《女界钟》带有过渡时期的某些特点,亦中亦西,希图摒弃传统追求现代。
