故宫的价值与故宫博物院的内涵   总被引:1,自引:0,他引:1  
故宫与故宫博物院密切相关,对故宫价值认识的程度,影响着对故宫博物院内涵的理解与功能的定位。故宫人对文物及其价值的认识有一个逐步深化的过程。博物馆不只是收藏“人类和人类环境的见证物”,更要在收集、保护、研究和传播上下功夫。故宫的古建筑不只是一个“壳”,更是中华传统文化的一个载体和标志,也体现了建筑艺术中各民族文化的交流和融合。在反映宫廷历史文化方面,故宫及其藏品可称为是明清皇家生活方式的标本,值得深入挖掘、整理和利用。从传统的古物概念扩展到保护文化遗产,是故宫人对故宫价值认识的一个飞跃,故宫不仅要保护有形的,而且要高度重视、努力抓紧保护无形的文化遗产。  相似文献

“以史为鉴”是历史学被高度政治化的1体现。结合中国古代史的发展轨迹做考察,就必须承认,“以史为鉴”可以导致两种不同的社会效用。正面效用,用作前车之鉴,直接导致了周、西汉、唐盛世的出现;负面效用,以防弊致弱的方式,影响到东汉、西晋、北宋等朝代的立制不良。对造成这两种不同效用的原因,应该正视和探讨。  相似文献

ABSTRACT

The structural analysis of a mirror-type vault, consisting of a single- or double-curvature perimeter and a nearly flat part, is carried out. The vault is similar to a number of hybrid iron (or steel) and masonry vaults built between the late 19th century and the early 20th century to span large halls. The numerical analyses were preceded by an accurate geometrical survey and mechanical tests aimed at evaluating the properties of the materials. Thermography allowed the complex brick pattern of the vault to be detected. The influence of rib-walls (frenelli) and the material anisotropy on the stress and deformation of the vault is discussed. Eventually, attention is focused on one of the segmental vaults in the central part of the structure: it is found that the stress can be safely estimated by assuming its boundary to be fixed.  相似文献

In 2008 a new notebook manufacturing cluster was established in Chongqing in western China. By 2013 it accounted for some 25% of world output by volume. Chongqing’s ability to attract this manufacturing supply chain was driven by several factors that permitted strategic coupling: the existence of complex networks of cooperation and economies external to the firm but internal to contemporary global production networks; changed conditions in southeast and east China; and the creation by Chongqing Municipal People’s Government with central state support of hard and soft infrastructures and externalities that drove down logistic and production costs and permitted constant product innovation.  相似文献

In the literature on territorial innovation systems there is a constant tension between the effect of endogenous and exogenous factors and their relative importance. In order to address this tension several approaches have sought to conceptualize the relational and multi-scalar dimension of innovation and to explain how external knowledge and economic flows in conjunction with regional contexts combine to produce regional growth, stagnation or decline. This paper will contribute to this debate, while also highlighting that even at the local level there is substantial heterogeneity between firms. It will also shed light on the role of intermediary organizations that can help address information and power asymmetries between multinational corporations and less competitive local firms. Empirically it will draw on the case study of the Portuguese moulds industry, which has successfully adapted to shifts in the global economy by drawing on local resources while also remaining integrated into global value chains.  相似文献

This paper examines the change in animation production over time and analyzes the different scales of internal and external linkages among six animation production centers. Four types of producers were identified based on their roles in the animation industry and their multi-scalar linkages were investigated for similarities and differences. Several factors including production costs, local skills, government policy and domestic markets were found to affect the growth of new production centers. High value-capture occurs mostly in production centers where tacit knowledge is created. The governance of each animation production center was found to have evolved based on its unique development path within the industry’s global value chain.  相似文献

This paper documents the results of in situ analysis of 306 lava paving stones and 74 possible source rocks using pXRF. Data were collected from sites both in the city of Rome—on major roads beyond the city (including the Viae Flaminia, Cassia, Clodia, Praenestina and Appia)—and in the city of Ostia. Comparison of the pXRF data with lava compositional data from the geological literature allows broad identification of possible sources. The results point to quite distinctive patterns of exploitation for the city of Rome and Ostia, utilizing the Alban Hills lava flows, and the roads of the middle Tiber Valley, drawing on lava flows associated with the Vico and Sabatini volcanoes. The results show the potential of pXRF to produce data to elucidate the exploitation of lava flows for paving the Roman roads.  相似文献

本文利用激光拉曼光谱仪和能量色散X-射线荧光光谱仪对21件取自故宫博物院院藏宋代官窑完整器及42件取自杭州老虎洞官窑窑址的青瓷样品表面釉层进行了测量与分析。通过计算瓷釉样品拉曼光谱中位于500cm-1附近宽带与位于1000cm-1附近宽带的面积比值(Ip值)及利用EDXRF分析样品的元素成分,讨论了这些样品的主要助熔剂成分Ca O、K2O含量与Ip值之间的关系,并通过对成分具有两类典型官窑瓷器釉料特征且在不同烧成温度下烧制的模拟釉块进行拉曼分析,对宋官窑青瓷样品的釉烧温度进行了讨论。  相似文献

景麟先生无论是在语言起源研究领域还是在文字与语言关系研究领域,均作出了重要而独至的学术贡献。《原"名"》一文之结论,在某种意义上可以说,乃景麟先生这两方面研究之出发点。从语言起源的层面看,是文出色地解决了语言起源之一大难题;从文字与语言关系的层面看,其有着难以替代之重要价值。就研究方法言,景麟先生将各自"独立"而又有极为密切联系之文字和语言的关系与语言起源作通盘考虑,所收乃1+12之效。  相似文献

文章在评述明清主要校本——冯校本、毛校本、赵校本、钱校本、陆校本、劳校本的基础上,着重强调了它们的史料价值,即为《乐府诗集》版本研究提供了材料和线索。诸校本中,冯校本、毛校本、陆校本和劳校本尤为重要。这些校本提供的材料帮助我们部分复原了亡佚了的两个宋本,并且使我们比较细致地了解到明末元本的流传状况和汲古阁校刻《乐府诗集》的诸多细节问题。  相似文献
