陕西蓝田水陆庵彩绘泥塑颜料分析研究

水陆庵位于陕西蓝田王顺山下,庵内现存三百余平方米精美绝伦的明代彩绘泥塑,是我国泥塑保存最多、最完整的明代彩绘泥塑群之一。为明确水陆庵彩绘泥塑的颜料使用情况,采用光学显微镜、X射线衍射仪、显微红外光谱仪、扫描电镜-能谱仪和显微拉曼光谱仪对颜料样品进行科学分析。结果表明,除中隔壁背面重妆区域的蓝色颜料主要成分是普鲁士蓝之外,水陆庵彩塑使用的颜料大多为矿物颜料,包括铅丹、朱砂、铁红、氯铜矿、雌黄和云母等。研究结果将为水陆庵后续保护修复提供科学依据,并为丰富关中地区明代彩绘泥塑颜料类型补充科学信息。     

北齐韩祖念墓出土玻璃杯考--兼论魏晋南北朝时期波斯玻璃器之东传

1982年太原北齐韩祖念墓出土了一件玻璃高足杯,我们用X射线荧光光谱对其进行了无损分析。检测结果表明:这件玻璃杯是典型的萨珊草木灰类型玻璃。结合器形、纹饰和文献记载,推测其应为波斯萨珊使者向北齐进献的贡品,为萨珊玻璃沿丝绸之路传播提供了新的证据。本文还对魏晋南北朝外来玻璃检测结果进行了总结,并系统划分了这一时期舶来玻璃的类型及其在中国分布的地域和时代特征。     

Seismic Retrofitting of Non-Seismically Designed RC Beam-Column Joints using Buckling-Restrained Haunches: Design and Analysis

Many existing reinforced concrete (RC) structures around the world have been designed to sustain gravity and wind loads only. Past earthquake reconnaissance showed that strong earthquakes can lead to substantial damage to non-seismically designed RC buildings, particularly to their beam-column joints. This paper presents a novel retrofit method using buckling-restrained haunches (BRHs) to improve the seismic performance of such joints. A numerical model for RC joints is introduced and validated. Subsequently, a new seismic retrofit strategy using BRHs is proposed, aimed at relocating plastic hinges and increasing energy dissipation. The results indicate the retrofit method can effectively meet the performance objectives.

New Historiography for the cultivation of the character of the “new citizen”: Liang Qichao’s ideas of history education and their practice

ABSTRACT

An advocate for modern Chinese historiography, Liang Qichao’s “new historiography” was ideologically quite closely tied to traditional Confucian historiography: his idea of “historiography” was both a form of scholarship for the provision of knowledge, as well as a type of learning for the cultivation of moral character. The fundamental objective of “new historiography” was to use the history of national development and evolution to educate the people, helping them to become nationally conscious “citizens.” However, according to Liang Qichao’s conception of history, the nationalist aspect of “new historiography” ultimately rested in the cultivation of individual character, not in imparting the concept of nationhood. During the movement to “systematize national heritage,” in his practicing of historiography, Liang primarily studied and compiled Chinese academic and intellectual histories, focusing particularly on Confucian history: he interpreted Confucianism and the cream of Chinese scholarship as a kind of “philosophy of life.” Liang’s historiographical practices eventually took shape as a form of moral education to cultivate the leading talents of society when the country was going through a transformation, while in the process signaling his profound repudiation of the empirical emphasis in historical research of the times.

枣庄市徐楼村红铜铸镶青铜器纹饰镶铸特征

红铜铸镶青铜器是春秋时期青铜艺术的杰出代表,红铜纹饰的镶铸特征是器物铸造工艺的直接反映,但红铜镶嵌青铜器的制作技术仍有许多问题有待于研究探讨。为此,通过直接观察法和X光成像技术,分析探讨了枣庄市徐楼村红铜铸镶青铜器纹饰镶铸特征。红铜纹饰有与器身基体等壁厚型和非等壁厚型两种。与器身等壁厚红铜铸镶纹饰和器身基体有平口直接镶铸和红铜预留凹槽镶铸两种方式。与器身非等厚红铜铸镶纹饰则利用红铜纹饰在器身浇铸时形成凹槽,红铜纹饰通过与纹饰相连的红铜支钉固定在范芯或在纹饰底部加入垫片方式镶铸于器物基体中。研究成果为红铜铸镶青铜器的工艺过程研究提供材料和证据。     

收藏絮语

小时候,常和父亲一起去逛家乡长春的桃源路旧货市场,俗称＂破烂市儿＂。那个年头,主要目的是选购一些实用而便宜的日杂用品,生活困难呗。但是,不排除也有点苦中找乐的意思。     

试论波斯对伯罗奔尼撒战争的介入

公元前431年爆发的伯罗奔尼撒战争既是一场希腊世界的内战,同时也是雅典与波斯之间侵略与反侵略的战争。远在东方的波斯在公元前412年与斯巴达结盟,介入战争。波斯介入战争的根本原因是其想重新占领在希波战争中失去的小亚细亚西海岸的希腊城邦,向雅典复仇。希波战争后波斯与雅典之间长期的"冷战",斯巴达主动向波斯抛出"橄榄枝"寻求结盟,以及雅典远征西西里的惨败,最终促使波斯与斯巴达结盟。战争期间,波斯主要通过小亚细亚的总督对斯巴达进行军事和财政援助。波斯的介入不仅帮助斯巴达战胜雅典,赢得战争的胜利,而且还直接引发了公元前411年的雅典贵族寡头政变,开波斯干涉希腊城邦内部事务的先河。     

滇越铁路与云南矿业开发(1910—1940)

1910年滇越铁路全线通车,大大改善了云南对外交通运输条件,推动了云南经济尤其是矿业的发展。滇越铁路的通车首先方便了个旧大锡的出口,大锡成为云南对外贸易的支柱产品,锡业也代替昔日的铜业成为云南矿业的命脉。滇越铁路还刺激了煤炭需求,促进了整个云南煤业的发展。不过由于滇越铁路管理权被法国控制,导致该条铁路产生的巨大收益外流,在一定程度上阻碍了云南矿业的进一步发展。
