三种含Cu、As绿色颜料的拉曼光谱研究

分析和确认古代颜料的成分是文物研究中的一项重要工作。为对四个来自不同地区的含Cu、As元素的绿色颜料进行鉴别,应用拉曼光谱仪并辅助以扫描电镜能谱分析仪(SEMEDX)和X射线衍射仪(XRD)进行研究。结果表明其分别为墨绿砷铜矿、氯砷钠铜石以及巴黎绿。对其来源分别进行了讨论,因巴黎绿在国内青铜修复和古建彩画当中的大量应用,过去对于含有Cu、As的绿色颜料通常鉴定为巴黎绿。墨绿砷铜矿和氯砷钠铜石为在文物彩绘中新发现的两种矿物颜料,为绿色颜料的鉴定提供了新的思路。     

Let there be light … and bread: the United Nations,the developing world,and atomic energy’s Green Revolution

Although President Eisenhower’s 1953 ‘Atoms for Peace’ speech typically is associated with the promotion of nuclear power, it also recommended other peaceful uses of the atom, including applications in agriculture. ‘Developing’ countries in particular took a keen interest in food preservation, grain disinfestation, fertilizer studies, insect control, and mutation breeding, all using irradiation. A conflict of philosophies emerged at the United Nations between the Food and Agriculture Organization (FAO) and the International Atomic Energy Agency (IAEA). The IAEA stood accused of promoting a narrow range of technological solutions, ignoring more sensible but less sensational techniques, and tempting the poorest countries of the world to achieve ‘modernization’ with unproven technologies. The present essay outlines the origins of FAO/IAEA conflict and collaboration in the 1960s, and explores the failed effort of plant geneticist Ronald Silow to stop what he saw as the IAEA’s hijacking of agriculture at the UN.     

“Where can we put our homes?” Gypsies and Travelers in the English Green Belt

For the past few centuries, anti-nomadic legislation has attempted to settle nomads who traveled throughout England and elsewhere in Europe, as their mobilities challenged the sedentarist goals of modern nation states. As recently as 1994, the nomadic way of life was effectively criminalized in England and Wales, revealing the unbalanced power relations between Gypsies and Travelers and the state. This article will examine and highlight the agency and spatialities of resistance of nomadic Gypsy and Traveler groups in England who are struggling for the recognition of their right to legally inhabit caravan sites in areas such as Green Belt land. The selection of places in the Green Belt for their homes offers another contested landscape that runs counter to the typical understanding of Gypsies and Travelers residing in marginalized places due to discrimination or wanting to remain unnoticed. By drawing from Gypsies and Travelers' own narratives, this article documents how they navigate through policies designed to constrain them.     

A female war correspondent on the Italian front, 1915–17: the Austrian travel journalist and photographer Alice Schalek

In July 1915, Alice Schalek was accredited to the Austro-Hungarian Kriegspressequartier (War Press Office) as one of a small number of female war correspondents, publishing her war reports and photographs in the prestigious Viennese newspaper Neue Freie Presse and in the illustrated German magazine Berliner Illustrirte Zeitung. Schalek’s writings and photographs were very popular, but also sharply criticized in some quarters for their alleged lack of objectivity and a tendency to glorify the war. Her most prominent critic was the Austrian writer and journalist Karl Kraus, whose negative judgment dominated Schalek’s historical reputation for many decades. Focusing on Schalek’s assignments to the Italian front during 1915–17, this article looks at the working conditions faced by Schalek as a female war reporter and reconstructs the war images she transmitted to the public through her writings, photographs, and lectures. Moreover, it asks in what ways Schalek’s work reflects a female perspective on the war.     

三国西晋时期越窑青瓷的生产工艺及相关问题——以上虞尼姑婆山窑址为例

三国西晋的越窑青瓷,品质、器类、装饰皆臻于顶峰。同时,生产工艺也达到极高的水准。文章以尼姑婆山窑址为例,从龙窑与窑具、装饰、成型、修坯、上釉、烧成等多个方面,论述了越窑青瓷的生产工艺,认为装饰、模制成型工艺最能代表当时的水平。这些复杂工艺在东晋以后失传,与北人南迁破坏了当地的制瓷传统,从而导致窑业萎缩的历史背景密切相关。     

乾卦六龙态的天文含义研究--《左传》"龙纪"历法钩沉

《左传》昭公四年的“龙纪”,是上古以苍龙星为历象的太阳历的记载。这个苍龙星星象在《易经》乾卦六爻爻辞中有形象的描述,根据寅月“见龙”、午月“跃龙”等记载,可知其观测年代当在夏代以前。这种借龙“以喻天之阳气”的龙纪历法流传至先秦秦汉,或称“易历”、“气历”;或称“律历”、“甲历”。它以天干记日,十日为旬,六旬为甲,六甲为岁,一岁360日;并通过不记在日序之内的56日的过年日使历年长度略等于回归年长度,从而形成了原始社会晚期一部较实用的历法。
