影响中罗关系曲折发展的若干因素

20世纪60年代,原本平稳发展的中罗关系出现了飞跃。促成并制约这一时期中罗关系发展的最主要原因是苏联对两国的影响,罗马尼亚领导人把中苏和罗苏两个双边关系变成了一个中一苏一罗大三角关系。此外,冷战的国际背景及由此产生的双方在意识形态上的认同与分歧,是另一个重要因素。上述因素在不同时期、不同情况下此消彼长,使中罗关系的进程呈现出缓与急、冷与暖的交替。     

Technological traditions inferred from iron artefacts of the Xiongnu Empire in Mongolia

Iron objects excavated from sites of the Xiongnu Empire (3rd century BC–2nd century AD) in Mongolia have been examined using optical and scanning electron microscopy. The results show that the Xiongnu iron tradition may be characterized by the use of low carbon iron and carbon control by carburization. Cast iron was also used in the Xiongnu Empire, but only in very limited applications and with no convincing evidence of its use for the production of low carbon iron. The Xiongnu iron technology seems to have been established on the basis of the bloomery technique, without much influence from the Chinese style of technology, based on cast iron.     

北方地区寺庙、殿堂壁画可溶盐活动规律的 实验室模拟研究

古代壁画的风化酥碱问题一直是壁画病害中最常见和最严重的问题之一,其主要原因是墙体中的可溶盐。了解壁画中可溶盐无机离子的特性及其活动规律可为解决古代壁画的酥碱问题提供科学参考和依据。为此,通过模拟壁画中可溶盐活动实验来揭示可溶性无机离子在壁画中的分布及活动规律。利用离子色谱仪检测分析壁画不同高度细泥层、粗泥层以及土坯层的可溶盐离子浓度。结果表明,试块细泥层中的Ca2+,Na+,和SO24-含量最高,说明这三种离子在壁画中的迁移能力最强,Cl-、NO3-、Mg2+的迁移能力居中,K+迁移能力最弱。离子迁移能力越强,在壁画表层富集程度就越高,各离子之间形成结晶盐的机率越大,对壁画破坏作用越大。本研究可为解决古代壁画盐害提供依据。     

实验室微型发掘方法在北周武帝孝陵 发掘中的应用

1994年经国家文物局批准,陕西省考古研究所对北周武帝孝陵进行了抢救性发掘,由于墓葬多次被盗,又多次进水,导致墓内的文物发生严重扰乱和腐蚀,尤其是墓内发现的大量易碎、细小及糟朽的有机质文物,使现场清理遇到了很大的困难。为了最大程度地获取地层中的所有考古信息,首次大规模、针对性地对孝陵五号天井东、西龛,四号天井东龛,甬道及墓室的文物采取了整体分割打包,运回实验室进行微型发掘的方法。通过对现场提取的74个石膏包的微型发掘和清理,获得了在现场无法发现的重要文物和遗迹,共清出文物2330件。尤其是直径不足1mm的无色琉璃珠在显微镜下的发现更是将微型发掘的优势凸显到了极点。它不仅弥补了现场发掘的不足,更是利用先进仪器,将考古发掘、科技考古和文物保护完美地进行了融合。实践证明实验室微型发掘方法是考古现场发掘不可或缺的必要手段。     

《滹南遗老集》版本源流考

《滹南遗老集》是金代著名学者王若虚的文集,这部著作编订于作者去世前后,初刻于金元之交,主持者为其子王恕与槁城县令董彦明、县丞赵寿卿。稍后疑有官刻本。初刻本传世甚少,元大德三年江西兴贤书院重新整理刊刻。明代仅有少量抄本流传,未见刊刻。清人吴重熹据明代淡生堂抄本收入《石莲庵汇刻九金人集》,此前已有《四库全书》,此后又有《四部丛刊》、《畿辅丛书》等收其文集。比较而言,《四部丛刊》本校勘最精,而《畿辅丛书》本收条最全。     

Palaeopathology in Britain: a critical analysis of publications with the aim of exploring recent trends (1997–2006)

This study collects data from three major journals and analyses them in order to assess the recent (1997–2006) nature of the study of palaeopathology within Britain. It considers the types of study published (case, population or method), whether findings are integrated with other data, the particular ‘theme’ that is considered (diet, activity patterns, etc) and the particular pathological condition focused upon (metabolic, dental, etc). The findings show there is a move away from the traditional case study and an increase in the acknowledgement of the value of integrating data with wider information. There is also a bias towards certain ‘themes’ and pathologies, reasons for which are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

河南省城市化与产业结构演变互动研究

文章在分析河南省城市化发展阶段性特征的基础上,对城市化和产业结构之间的变动关系进行了对比分析、相关分析和回归分析,并用Arcgis9.3以"产业结构演变城市化响应系数"为指标绘制地图,反映了河南省城市化与产业结构之间作用强弱的空间差异,分析表明,河南省城市化与产业结构存在严重偏差,原因在于城市化与产业结构的非协调发展和产业结构与就业结构的不合理发展;河南省的产业结构演变城市化响应呈现"西高东低"、"北高南低"的地理分布特征。最后针对问题提出了对策。     

A preliminary study on the role and implication of plate-type iron artifacts in the ancient iron technology of Korea

Special iron objects in the form of a narrow plate with a fan-shaped blade on one or both ends, but with a substantial variation in shape and size, have continually been excavated from ancient historical sites located in the southern part of the Korean peninsula. The frequency and abundance of their excavation imply that they must have played a crucial role in the initial shaping of the Korean iron industry. Little is known, however, of their intended purposes or the exact engineering processes applied in their production. Speculation suggests that they might have been used as currencies or intermediate materials for the making of finished products. This study examined the microstructures of three such iron objects from the Korean Three Kingdoms Period (ca. 300–600 AD). It was determined that they were made of low carbon iron generally containing a number of non-metallic inclusions, with hints of surface carburization particularly at the ends of the plates. These results reveal the likely presence of an iron technology based primarily on the bloomery technique as opposed to the Chinese style of iron-making based on cast iron technology, which was also in use in ancient Korea.     

甘肃省永登县连城鲁土司属寺壁画的科学分析和时代研究

本项研究主要是运用光学显微镜、扫描电子显微镜和共聚焦显微激光拉曼光谱技术,分析了甘肃永登连城鲁土司属寺中的妙因寺、感恩寺和雷坛中的部分壁画。分析结果表明感恩寺和雷坛壁画基本保持了明代最初的绘制风格和内容。其中感恩寺主要壁画的绘画颜料和工艺特点鲜明,表明绘制该壁画的画工不同于绘制鲁土司属寺其他壁画的工匠;妙因寺万岁殿壁画存在后期改动和重绘的情况,其中万岁殿外回廊壁画主要部分的最初绘制时间要早于万岁殿大殿内壁画的最后绘制时间;而妙因寺塔尔殿壁画则绘制于19世纪后期。     

新中国成立以来内蒙古生态环境变迁个案研究——喀喇沁旗王爷府镇大富裕沟村生态环境变迁及其原因

大富裕沟村位于内蒙古赤峰市西南部山区,20世纪40年代以前,这里植被茂密,生态环境较好。六七十年代,生态环境遭到严重破坏,村民的生产生活陷入困境。90年代以后,被破坏的生态环境得以逆转。该村生态环境由好变坏的原因:其一是人口增加超过了生态环境的承受极限,其二是传统的农牧业生产方式和相对应的生活方式在人口达到环境承受的极限后成为破坏环境的人类活动模式。该村生态环境由坏变好的原因:其一是计划生育政策和城镇化引发的人口大幅度减少,从而减轻了生态环境的压力;其二是现代化的生产和生活方式大大减少了人类活动对资源的索取,其三得益于70年代开始的对生态环境的不遗余力的保护政策和措施。
