蒙东地区与东北三省煤炭资源开发的区域合作研究

我国蒙东地区与东北三省煤炭资源开发的区域合作是建设新兴的蒙东资源基地和振兴东北老工业基地的必然要求。通过在蒙东地区及东北三省的深入调查,发现这两大区域煤炭资源开发的区域合作已经形成一些典型案例,可以分别从上级政府强势干预、地方政府积极推动、中央、地方、企业联动、企业自发参与这四种模式来认识这些案例所反映的区域合作特征、效应与问题。为深入推进蒙东与东北三省煤炭资源开发的区域合作,政府干预应着重协调区域合作的地区格局,促进企业的多元参与,建设跨地区运输通道与生态工程,推进地方政府间的配合与协调。     

Foddering by Mongolian pastoralists is recorded in the stable carbon (δC) and nitrogen (δN) isotopes of caprine dentinal collagen

Direct identification of fodder provisioning in individual animals is a previously unexplored area that has important implications for determining animal husbandry strategies in prehistory. In this study, foddering practices are examined in modern domestic and wild caprines from Mongolia (Baga Gazar'in Chuluu) through carbon and nitrogen analyses of bulk sampled dentin collagen in molar teeth. Foddered caprines display significantly different δ¹³C values compared to non-provisioned caprines. This pattern reflects the consumption of C₄ plants year-round by provisioned caprines while non-provisioned caprines ingest C₄ plants only during the summer months. Provisioned caprines also display significantly different nitrogen isotopic values relative to non-provisioned animals. The difference in nitrogen isotopes between wild and foddered animals may be due to increased access in quality graze through foddering by domestic caprines, which results in improved nutrition and extended lactation periods, or enriched δ¹⁵N of fodder plants relative to background flora. Differences in tooth wear between sampled wild and foddered animals may also contribute to the observed δ¹⁵N differences.     

大朝国师印考

西藏自治区文管会珍藏的“大朝国师统领诸国僧尼中兴释教之印”是具有极高历史价值的国宝级文物。但是,它长期被误读,并认为是复制品而遭到冷落。实际上“大朝”是忽必烈正式建国号“大元”之前的蒙古汗国国号,国师是当时最高僧官,具有“统领诸国僧尼中兴释教”的职权。此印是蒙哥大汗赐予那摩国师的封印。本文揭示了该印重要的历史价值和文物价值,对于元史、蒙古史的研究都有重要的参考价值。     

钴蓝颜料（Smalt）在故宫建福宫彩画中的发现

钴蓝颜料（Smalt）是一种产自欧洲的进口蓝色颜料,是一种经过研磨的钴玻璃粉末,从十五世纪中叶开始广泛用于欧洲油画与壁画中。在故宫的建福宫中发现有这种钴蓝颜料（Smalt）。但在明清文献中,钴蓝颜料（Smalt）尚无明确记载。本文主要对始建于乾隆七年（公元1742年）的建福宫内檐脊枋彩画进行了调查和采样,采用显微镜分析和显微激光拉曼光谱分析蓝色颜料的种类和彩画结构,特别是钴蓝颜料（Smalt）使用的时代和分布进行了认真的研究。分析结果表明：建福宫建造时,靛蓝是一种经常使用的蓝色颜料,故宫建福宫钴蓝（Smalt）颜料的使用时代晚于建筑的建成年代（公元1742年）,而且一般与颗粒大小接近的石青混用。     

古代小说中的龙宫及信仰文化考述

龙宫原为佛教文化意象,当其以文学意象的身份进入我国古代小说后,成为小说作品中的一个常见文学形象。受时代的小说创作潮流、创作群体以及受众层次变化的影响,唐宋小说与明清小说中龙宫的文化内涵及美学旨趣产生变化。历代小说中龙宫意象即在这种历史的变迁中不断发展丰富,构建起意蕴深厚的龙宫信仰文化。     

古物陈列所的兴衰及其历史地位述评

成立于1914年且存在了34年的古物陈列所长期被人们忽视并淡忘。它实际上是中国近代民主革命的光荣产物和反复辟斗争的重要成果,曾占据今日故宫博物院的半壁江山,被誉为“民国成立后最有价值之建设”。它是紫禁城向博物馆转变的第一篇章,是中国第一家国立博物馆、宫廷博物馆、艺术博物馆,开创了中国近代博物馆发展史的新纪元,在世界宫廷类博物馆中占有特殊地位,在中国近代政治、社会、文化史上也具有较深远的影响。

A technological transition in Mongolia evident in microstructure,chemical composition and radiocarbon age of cast iron artifacts

Metallurgical examination of cast iron objects from the Khitan period (AD 10th–12th) in Mongolia shows that they might be classified into two groups. The first is based on Fe–C alloys of near eutectic composition and the second is based on Fe–C–Si alloys with reduced carbon content and numerous sulfide inclusions. By contrast, all the objects from the succeeding Mongolian empire period (AD 12th–15th) belong to the second group, indicating that a technological transition had occurred during the Khitan period. Accelerator mass spectrometry (AMS) on carbon samples extracted from artifacts in both groups and measurement of alloy compositions suggest that the use of mineral coal in smelting was a major factor for this transition.     

Investigation of Organic Materials From the ‘Royal’ Burials of Xiongnu (Noin‐Ula,Mongolia) by Srxrf and XAFS Methods

The burials of famous Xiongnu people are a unique source of information about Xiongnu culture, due to the variety of organic findings. SRXRF analysis of hair, clay, bones, teeth and woollen cloth was carried out. An anomalously high copper content was observed in all hair samples, whereas the levels of copper in bone and clay were low. To define the hair morphology and the elemental distribution in the hair cross‐section, high‐resolution X‐ray computed tomography (HRXCT) and energy‐dispersive spectroscopy (EDS) with scanning electron microscopy (SEM) were used. The X‐ray absorption fine‐structure method (XAFS) was applied to determine the local copper environment. The majority of the copper species in the hair and enamel samples are present as Cu²⁺ cations in a distorted octahedral (4 + 2) coordination, surrounded by light ligands (oxygen/nitrogen). A similar distorted octahedral coordination is typical for both inorganic mixed oxide/hydroxide Cu nanosystems and metal–organic Cu complexes (with oxygen/nitrogen).     

故宫太和殿二层斗拱竖向加载试验

为了更好地保护古建筑,采取静力试验方法,以故宫太和殿二层平身科、柱头科、角科斗拱为对象,研究了竖向荷载作用下斗拱的受力性能。基于上述3种斗拱构造特征,制作了1∶2比例模型,进行了竖向加载试验,讨论了不同斗拱在荷载作用下的破坏形式、内力及变形特征,归纳了斗拱的竖向刚度计算模型。结果表明:竖向荷载作用下,太和殿二层斗拱的坐斗及与之相交的头翘、正心瓜拱容易产生破坏,且模型倒置时下层构件受力要小于上层构件。对于不同斗拱而言,斗拱极限承载力:平身科角科柱头科;斗拱变形及残余变形量:柱头科角科平身科;斗拱延性:角科柱头科平身科。竖向荷载作用下,太和殿二层斗拱的竖向刚度计算模型可简化为三折线段形式。
