The results obtained from the multi-analytic compositional characterization of ceramic pastes and paints of the Santa María style, from the El Bolsón valley (Belén Department, Catamarca Province, Argentina), are presented here. This pottery style had a wide regional distribution in Northwestern Argentina between ca. 1000 and1600 ce and is characterized by its complex iconography painted in black, cream and red. The analyses show that the containers correspond to the technical tradition of using grog temper and suggest that its manufacture involved a double firing process. This reveals a new practice for the time.  相似文献

The number of finds relating to metalworking, without evidence of mining and processing facilities, is very limited. In Final Eneolith graves of specialized metallurgists that have occurred, they contain a metal-founding or metalsmithing toolkit, whose origins were from eastern Europe (the Maykop, Yamnaya Culture). Such metallurgical tools may have reached central Europe as part of the so-called Yamnaya Package before the onset of the Bee Beaker Culture (BBC); and unlike the Pontic region, these two types of metallurgy separated here. There are found an accumulation of metallurgists' graves in Moravia, where the complete metalworking toolkit is deposited in a predefined place in richly furnished male graves with a distinctive funerary architecture that exhibit a clear relationship to the grave goods. EDX-analysis detected a high content of metals (Cu, Ag, Au, Au–Ag alloy) on all working surfaces of stone tools, grinders, and boar tusks used for the final treatment of their metal products. This makes us believe that the used artefacts were laid as symbolical objects in the graves of these craftsmen who perfectly knew these advanced technologies. Due to their knowledge, their social significance gradually rose and finally reached the level of social elites, who were usually buried in a spectacular manner, including the quantity of grave goods (Überausstattung) and the pars pro toto deposition in one part of the finds.  相似文献

西安城墙东门箭楼砖坯墙体风化因素研究报告   总被引:2,自引:2,他引:0  
论述了西安城墙东门箭楼的文化背景,实地考察了风化外状,并对风化外状进行了分类测试。通过对砖坯墙体材料进行化学全分析、X-射线衍射分析、吸水率测定(含他和系数)、冻融实验、泛霜实验、环境污染与水文气象监测资料的分析,研究了东门箭楼砖坯墙体不同风化外状的风化因素,同时对现代修缮用砖的理化性能及质量进行了评估。结果表明,温度的交替变化、水的冻结与融化使得砖坯裂解成碎块;干湿引起可溶盐的结晶与潮解以及自然界中的雨水、地面水或地下水、污染气体等通过溶解、水化、水解、碳酸化、氧化等方式,使得砖坯墙体表面酥碱粉化。同时说明研究适用于古建筑修缮使用的抗风化仿古青砖是当务之急。  相似文献

南宁市房地产业经历了由沉寂、复苏、火爆到稳步发展的过程.各公司开发的房屋类型相近,但价格差异却很大,价格分布呈现明显的规律性:一是城市中心价格高,边缘与郊区价格低;二是东部城区价格高,西部城区价格低.主导价格分布规律的三大影响因子是地理位置、交通便捷程度和生态环境质量.南宁今后的房地产开发和城市规划建设一要顺应价格分布规律,优地优用、保障房地产开发的高效益;二要加强交通设施建设和环境保护.促进全市房地产的升值;三要因势利导,发展城市副中心,逐步形成多中心的城市建设格局。  相似文献

明墓出土的历书,粘连固结成块,脆硬易于折断。通过实验分析研究,探明其主要原因可能是木质素选择性地吸附的钙铁离子与蛋白质的分解物形成复杂物质,沉积在纸上,渗入书内所致。故揭取该历书的关键是去除钙离子,EDTA二钢,碱性过氧化氢、气相二氧化硅等的分步处理,使脆硬的纸张软化,再逐页分离揭取,然后再去除色素沉淀物,终于恢复了书的原貌。  相似文献

Several samples of pyramids from Giza were obtained. The samples were analysed by scanning electron microscopy, electron diffraction by X-rays, powder X-ray diffraction, inductively coupled plasmography, Fourier-transform infrared spectroscopy and other techniques. Some scientists who have recently studied the pyramids have suggested that the pyramids were poured into place, stone by stone. The prevailing theory among Egyptologists is, of course, that the pyramids were built from blocks of natural stone. All of the results obtained during this study directly support the concept that the pyramids are made of limestone and are not cementitious in nature.  相似文献

About 200 analyses have been made on late Roman and Sassanian silver objects using energy-dispersive X-ray fluorescence. This has shown that the main feature of the composition of the silver throughout the period and across the geographical area studied was towards high fineness (average silver percentage about 95%). Compositional differences are found between Roman and Sassanian silversmiths' products for the elements copper and lead. Much of the material analysed came from hoards, and using a statistical technique on the analytical data (Discriminant Analysis) broad compositional differences between hoards were found to emerge. The use of different compositions of silver for different joined parts of a single object are discussed.  相似文献

岭南僻处南疆,地理复杂。隋末大乱之时,地方势力纷纷割据,唐初和平统一岭南后,采取羁縻政策,以原有势力为基础设管州的"都府"。而在都府之上,朝廷以广州、桂州、交州为中心置"统府",以点控面,有效地维护了岭南地区的稳定。但是这种层层管理的"统府三分格局",到高宗乾封二年发生突变,随着邕府和容府的建立,原统府消失,遂形成并立的"五府格局"。可是,最迟8世纪初,唐朝设立岭南五府经略使,统一管理整个岭南的军事。在此前后,岭南选补使、岭南按察使、岭南采访使等陆续出现,在人事、监察、民政等领域,对岭南道全境实施管辖权。因此,"盛唐"的岭南道,表现出明显的"归一"趋势。  相似文献

20世纪60年代,叙事学作为一门学科始于西方历史学、文学领域。直至20世纪末,叙事学开始转向空间领域研究形成空间叙事学,并被逐步应用到城乡规划中,尤其是城乡空间结构等领域。空间叙事学不仅关注城市发展中的物化要素,更加注重物化要素所代表的城市文化和城市记忆等非物化要素的深入挖掘,是探究场所本体与场所精神的重要研究思路。本文从空间叙事学出发,基于GIS平台运用核密度及K函数对古代、近代、现代三个时期沈阳旧城区人工叙事要素和人文事件叙事要素进行点模式量化分析,得出沈阳旧城区叙事空间的总体结构,以及叙事点核、叙事廊道、叙事簇群等叙事空间结构单元,指出沈阳旧城区叙事空间的动态发展性、功能多样性和历史传承性特点,探讨了叙事空间的经济驱动、自然要素、城市定位和交通发展四大演变机制。从人文地理学的视角出发,结合叙事空间理论对沈阳旧城区叙事空间进行分析,结果具有文化地理和城市地理双重属性,丰富了城市研究在该视角下的研究成果。  相似文献

This paper examines settlement density and settlement patterns in the Roman colonial territories of Venusia, Cosa and Aesernia, located in three different landscapes of central southern Italy (modern Basilicata, Tuscany and Molise). Using a series of GIS tools, we conducted a comparative analysis of the density and spatial distribution of sites dating to the Hellenistic period (ca. 350–50 b.c.). We used the legacy settlement data collected by previous large-scale, intensive, site-oriented field surveys to test the validity of two competing rural settlement models of early Roman colonization: the conventional model of neatly organized settlements regularly dispersed across the landscape and the recently proposed theory that colonists adopted a polynuclear settlement strategy. After calculating the extent to which the archaeological datasets conform to the regular or polynuclear model, we conclude that only a very small portion of the colonized areas actually meets traditional expectations regarding the organization of early colonial settlements. Our analyses show that the legacy survey data is more consistent with the polynuclear settlement theory, but the data also reveals some completely unexpected patterns, suggesting that early Roman colonial landscapes were more diverse than previously thought.  相似文献
