浙北土墩墓遥感考古研究

环太湖地区包括浙北地区是我国长江流域重要的古文化遗存分布区,仅浙北地区的土墩墓就有上万个。近四年来的遥感考古工作,已获得不少关于土墩墓的影象特征和土墩墓分布规律等的研究成果。航空遥感照片上的土墩墓的影象大小、色调、灰度、形态等是土墩墓解译的基本依据;同时影象所在的地貌部位,海拔高度是土墩墓解译的重要参考依据。浙北土墩墓主要集中在长兴和安吉两县,湖州市郊的西部也有较多分布,而德清和余杭土墩墓较少。浙北土墩墓的分布类型有山脊型、山麓型和平原高地型;浙北土墩墓就形态而言,有卵圆形、圆形;面积也有大中小之分,大者底径可达50余米,小者仅3-5米;另外就土墩墓的组合而言,有串珠型、集群型和离散型。土墩墓集中分布在海拔50-200米的丘陵缓坡上,海拔略高的平原岗地上也有较多分布,这种分布特征与古地理环境是有联系的,从一个侧面反映了古地理环境特征。     

珂罗版复制在书画文物保护中的作用

珂罗版印刷是一种古老而精妙的平面印刷技术,珂罗版印刷在印刷复杂的书画作品时,特别是在中国古代书画的笔触和墨韵表现上,可以最大限度地体现原作的艺术特色,达到其他印刷手段难以企及的艺术境界。珂罗版印刷与人工设色相结合,提高了人工临摹的工作效率使古老珂罗版印刷更具艺术生命力,成为复制书画文物的最佳手段。     

Seismic vulnerability assessment and fragility analysis of stone masonry monastic temples in Sikkim Himalayas

Buddhist monasteries in Sikkim Himalayas constitute important religious and architectural heritage. These random rubble (RR) stone masonry structures located in high seismically active regions of the Himalayas have suffered varied degrees of damages in the past earthquakes. The study presents seismic vulnerability assessment of four archetypal monastic temples using finite element (FE) analyses. Linear and nonlinear analyses of these structures were conducted in Abaqus FE environment. These analyses identified the damage prone areas of the structures and provided load-deformation behavior under lateral loads. Fragility analyses indicate a high probability of collapse for the specified design level earthquake of the region. The study shows that performance of the structure can be enhanced by improving the strength and stiffness of the stone masonry walls.     

近代江南地区工商业会馆、公所碑刻述论

在现有的行会制度史研究中,尚无专文对碑刻本身进行探讨.本文认为:刻石立碑是行会活动的一项重要内容,是工商业会馆、公所从社会合法性到政治合法性的一个重要标志,是行会受到封建官府保护的象征.在会馆、公所等行会组织的发展中,碑刻具有传承后世的记忆功能、惩戒违规的警示功能、颂扬美德的激励功能、公布官府法令的告示功能以及征信与佐证功能,有助于形成行业的凝聚力和从业者的自豪感,增强会馆、公所的权威性和同业商人对行业的归属感及维护行业利益的责任感,约束违规违法行为,对会馆、公所的变迁与发展具有不可替代的作用.     

Evaluating effects of chemical weathering and surface contamination on the in situ provenance analysis of building stones in the Cuzco region of Peru with portable XRF

As the only type of instrument capable of determining artifact geochemistry in a wide variety of settings, portable X-Ray Fluorescence (PXRF) may be frequently utilized as probably the best option for collecting data when removal of objects in part or in whole is unfeasible. However, using PXRF in circumstances where sample selection and preparation diverge from standards developed for lab-based instrumentation requires assessing the impact of new and potentially limiting factors to establish the validity of the method in these new contexts. Here we examine the effects of surface contamination and chemical weathering on the ability to assess provenance of igneous building stones used in the Cuzco region of Peru. Surface contamination was assessed through comparing low-impact cleaning methods on diorite and andesite blocks, and weathering was examined by comparing weathered vs. fresh surfaces of samples from two andesite quarries. In general, the lightest elements were most impacted by contamination and weathering while measurements of many of the heavier elements commonly used in provenance studies were relatively unaffected. Concentrations of Pb and Zn were problematic in the urban context of Cuzco because of pollution. Ability to determine provenance of building stones within those limitations (i.e., the validity of this application of PXRF) was demonstrated in a preliminary study by comparing measurements from uncleaned, exposed building stones in the region to fresh quarry samples.     

Ballistically anomalous stone projectile points in Australia

The emergence of stone-tipped projectile weaponry was an important event in hominin evolution. A common archaeological approach to identifying projectile weapons is to extrapolate from optimal values of ballistically-relevant attributes as determined from ethnographic North American weapons and modern experiments. Among the most significant of these attributes is “tip cross-sectional area” (TCSA) because it determines a point's efficiency in penetrating an animal. The warranting argument for projecting these data onto prehistoric artefacts is that past “research and development” necessarily led to stone projectiles with optimal TCSA values for a given delivery system. However, our test of this warranting argument, involving analysis of 132 hafted ethnographic Australian stone projectile points and 102 hafted knives, demonstrates that Aborigines did not optimize TCSA values, thus offering a challenge to TCSA-based narratives about the first appearance of projectile weaponry. This illustrates the difficulty of inferring ancient stoneworkers' design intentions from narrowly-defined optimal values. Instead, tool designs should be considered in the context of the reduction sequences that produced them and the dynamics of transmission of those reduction sequences across generations.     

河南境内出土早期玉器初步研究

综合利用PIXE、XRD和Raman三种无损分析方法,准确判明了河南出土新石器时代至东周90余件玉器的质地,这些玉器的玉材种类非常丰富,并具有时代和地域特色。新石器时代至夏代,河南透闪石型玉器很少而绿松石占绝大多数,商代开始透闪石激增并占据主体地位。根据绿松石的类质同像、伴生矿物或围岩成分及透闪石所舍微量元素,探讨了玉...
