141年前,李鸿章和森有礼曾就日本军舰“云扬号”入侵朝鲜江华岛事件以及学习西方、变革服制、举借外债等问题在保定展开了一场激烈的论战。本文考察了森有礼于光绪元年腊月二十八日赴直隶总督府与李鸿章举行会谈的背景,并基于1899年出版的《森先生传》中揭载的对话记录,译介、分析了这场对话的主要内容;指出,尽管李鸿章组建了一个人数众多的幕府,但由于无法破除人身依附关系,未能建立独立的智库,以致他很难听到不同的意见,学到有价值的新知。因此,李鸿章与森有礼论战时无法占据明显优势也就在所难免。  相似文献

According to tradition, King Richard I of England visited Dubrovnik (Ragusa) in 1192. Much of the evidence for this visit comes from a dispute at the end of the sixteenth century concerning the rights of the abbot of Lokrum. Medieval evidence can also be taken into contribution, notably the comments of the English chronicles of the early thirteenth century and the surviving documentation for the career of a Ragusan archbishop who later became bishop of Carlisle. The author concludes that King Richard's visit was a reality.  相似文献

乡村振兴要求走乡村内生性发展道路,客观认知乡村发展能力的时空分异格局和交互关系对乡村振兴战略实施具有重要意义。本文从农业产业发展、农村基础建设和农民社会生活三个维度构建测度指标体系,并引入面板向量自回归模型识别影响乡村发展能力的敏感因素,以此测度乡村发展能力指数,进而采用探索性时空数据分析方法揭示乡村发展能力的时空交互特征。结果表明:(1)我国中部地区多维乡村发展能力提升,但呈明显的空间异质性,不同维度间差异化显著;(2)中部地区多维乡村发展能力局域空间格局呈现较强的动态性并整体表现出较强的空间依赖关系;(3)邻接地级市多维乡村发展能力的时空交互网络以正向关联为主,局部空间呈差异化的竞合态势。  相似文献

史前漆膜的分析鉴定技术研究   总被引:5,自引:0,他引:5  
研究了漆膜分析的三种主要方法:裂解质谱,红外光谱,裂解色谱。通过大量实验比较了各种方法的适应性和可靠性,建立了以裂解色谱/富里叶红外光谱联用技术来鉴定漆膜,并对影响裂解反应的因素及色借条件进行了深入的研究,获得了可以重复,具有特征性的漆膜高分辨裂解色谱图,同时对裂解色谱图中主要组分作了定性鉴定,提高了裂解色谱法分析漆膜的可靠性。该方法具有灵敏度高,样品用量小,共存杂质影响小,操作简便等优点。应用核分析技术对河姆渡,良诸庙前遗址出土的二件红色涂料样品进行了鉴定。分析结果证实了河姆渡出土的红色涂料木碗上的涂料是我国至今发现的最早的生漆漆膜。  相似文献

This study takes a valuation perspective to study how and where products and innovations are gaining ‘economic significance’ in the contemporary economy. Building on a recent research stream in economic geography and urban and regional studies, it highlights that the economic value of many products is not formed within production systems alone, but relies on co-constructed connections between production and consumption systems, playing out across multiple geographies. It distinguishes between three types of economic valuation pathways – namely technical, experiential and identity-based – which although analytically distinct may actually build and reinforce one another. This approach is empirically illustrated with the case of the surf-related economy in the city of San Sebastian (Basque Country, Spain), which is used to make a broader point about the growing relevance of a valuation approach to understand competitive advantage and economic renewal in localized production systems.  相似文献

Shear walls are important lateral force-resistant components of tall buildings. Hence, a reliable numerical model that can accurately represent the mechanical characteristics and large deformations of shear walls is critical for realistic collapse simulation of tall buildings. Based on the theory of generalized conforming element, a high-performance quadrilateral flat shell element, NLDKGQ, accounting for the large deformation using the updated Lagrangian formulation, is proposed herein and implemented in OpenSees. The reliability of NLDKGQ is validated using classical benchmark problems and reinforced concrete specimens. In addition, its capability in simulating the collapse of a tall building is also demonstrated.  相似文献

The concept of providing a fuse in a structural system has been both developed and investigated over the past few years (e.g., the use of replaceable links in eccentrically braced frames or the use of replaceable links in the new San Francisco-Oakland Bay Bridge). This paper presents a new coupling beam with a creative fuse installed in the mid-span of a steel-concrete composite beam via an end plate and high-strength bolts. First, a practical design methodology of a replaceable coupling beam is presented. Next, the seismic behavior of the proposed fuse is tested and evaluated, and two structural wall specimens with or without a fuse are designed and fabricated according to the proposed design methods. The two specimens possess similar shear capacities under large-scale cyclic loading, and the walls of the two specimens show similar failure modes; however, the new walls exhibit slightly lower levels of damage than the conventional walls. In particular, the inelastic deformation and damage of replaceable coupling beams are mainly concentrated in the fuse, whereas the non-yield segment and the beam-wall pier interfaces remain nearly intact and produce only slight damage, which is beneficial regarding the replacement of the fuse in post-earthquake events.  相似文献

国内外瓷器修复的基本流程没有很大差异,但是西方国家生产的修复专用材料品种较丰富,值得国内修复界吸收与应用。为此,本研究着重对Hxtal NYL-1、Golden Porcelain Restoration Glaze、Golden Polymer Varnish with UVLS三款瓷器修复专用产品开展分析研究。测试结果显示,在国内外5类环氧树脂中,Hxtal NYL-1的拉伸强度最低,断裂伸长率最高。Hxtal NYL-1在波长365nm的紫外线照射78d后,其色差变化最平稳。紫外可见光谱数据显示Golden Glaze仅吸收一定的中波紫外线UVB,Golden Varnish对长波紫外线UVA和中波紫外线UVB都具有吸收能力。波长365nm紫外老化实验可证明Golden Glaze和Golden Varnish都具备较好的光稳定性。而在254nm紫外老化环境下,Golden Varnish表现出更佳的抗紫外性能。此外,围绕瓷器修复实例,对这些产品的在修复中的使用方法进行了简要梳理。  相似文献

This paper deals with the cultural and educational relations between the United States and Portugal during the Cold War. It is built upon the premise that cultural policies and cultural relations between states are a fundamental part of international relations. History of International Relations, therefore, should overcome an analysis based only upon political and diplomatic dimensions to address what can also be referred to as ‘cultural diplomacy’. The Cold War period, because of its historical features, is particularly relevant to the study of processes of cultural diplomacy and some authors even consider it as the ‘golden age’ of cultural diplomacy.11.

"原状"认识来源于西方经典保护理论,历经启蒙运动、法国大革命和反修复等社会运动。至19世纪,其思想内涵不断发生变化,从单纯地强调"原物""原状"发展到将历史真实的"原状"观念扩大到历史时间和"环境"等更大的对象范畴。20世纪以来,经典保护理论走向成熟,"原状"也真正从追求"原物真实"走向了传递其蕴含的"价值意义"。"不改变原状"是我国文物古迹保护的核心原则,经历了"初建时的原状""整旧如旧"、对于"原状"的多元释义、"体现价值的状态"等四个阶段。文化遗产的保护要从原物、原信息、原地点、原场所精神、原用途五个方面综合考虑"原状",才能真正保护好遗产的价值。  相似文献
