泉州湾宋代海船保存现状的调查研究   总被引:2,自引:0,他引:2  
作为国内乃至亚洲大型海洋出水木质文物保护的先例,泉州湾宋代海船自出土至今已保存近40年,经过多年来综合性地保护修复,其保存现状值得关注。本文通过对古船保存环境、船体构件保存状况、船体病害、材质状况的调查分析,综合评估船体保存现状,分析影响古船稳定保存的主要因素,从而为后续的保护工作奠定基础。  相似文献

石窟造像防风化加固材料探讨   总被引:1,自引:0,他引:1  
石窟造像文物具有不可再生性,因此对其保护加固材料的要求非常苛刻,除需具有很好的粘连性、渗透性、透气性、耐候性、疏水性和化学稳定性外,还需具有一定再处理性,且对石窟造像本身无副作用.本文通过对石质文物防风化加固保护材料的梳理,分析了各类保护材料的优缺点和适用性,为我国石窟造像防风化加固保护设计、施工材料选择和应用提供基础资料.  相似文献

利用XRF、金相显微分析等手段对湖北省荆门市境内左冢楚墓群出土的金属器,特别是青铜器进行了测试分析,XRF分析表明该楚墓群出土的青铜器多为铜、锡、铅三元合金,且容器的锡含量低于兵器和工具,而铅含量则相反。金相分析显示左冢楚墓群出士青铜器多为铸造组织,其中3件铸后经过不同程度的加热:而热锻成形的器物有4件,其中有一件在锻后进行了冷加工。结果显示,此批青铜器合金成分比较科学、制作工艺比较先进。  相似文献

1951:唯物史观派主流地位的确立   总被引:2,自引:0,他引:2  
蒋海升 《史学月刊》2004,(12):96-102
1951年,唯物史观派对于学术机构领导权和学术期刊经营权的掌握和控制以及自身社会地位的提升,使他们成为在学术界确立新意识形态的主导地位、推动学术变革和话语转换的中坚力量;唯物史观派聚拢传统学人进行史料整理、古籍校订,为学术史留下一笔财富。1951年前后唯物史观派主流地位的确立和当时学术格局的变动直接影响了20世纪后半期学术界的走向。  相似文献

During the Late Intermediate period (LIP, c. A.D. 1000–1400), the central Andes experienced the decline of the Wari and Tiwanaku states, as well as processes of state formation, regional population growth, and competition culminating in the imperial expansion of the Chimú and Inka polities. The LIP holds the potential to link the archaeological features of early Andean states with the material signatures of the later ones, providing a critical means of contextualizing the intergenerational continuities and breaks in state structures and imperial strategies. The recent proliferation of LIP research and the completion of a number of regional studies permit the overview of six LIP regions and the comparison of highland and lowland patterns of political and economic organization, social complexity, and group identity.  相似文献

Ongoing excavations at Olduvai Gorge, Tanzania, reveal tremendous variability among stone artifact assemblages across the Plio-Pleistocene Olduvai Lake Basin during Bed I and lower Bed II times. Theoretically, stone artifact traces of Oldowan hominin land use are determined by the distribution of larger mammal carcasses and arboreal refuge from predation as well as proximity to stone material sources.  相似文献

Bitumen, found in abundance in Mesoamerica’s southern Gulf Coast region in natural seeps and in many archeological contexts, is an important economic resource and exchange item that has received little consideration in Mesoamerica. Analyses of archeological, ethnoarcheological, and experimental data provide insights on the organization of bitumen processing activities, and the end product (archeological bitumen), which the Olmec (1200–400 BC) used in the production of many items. Archeological data are derived from investigations at El Remolino and Paso los Ortices— two Early Formative period levee sites in the San Lorenzo Olmec region. Our findings suggest that among the Olmec, bitumen processing was organized as a specialized activity, involving multiple production stages, but not necessarily elite involvement or control.  相似文献

The late Stone Age Pitted Ware site at Ajvide, Gotland, in the Baltic Sea, Sweden, has revealed a large deposit of fishbone and approximately 400 bone fishhooks, complete and incomplete. Cod (Gadus morhua), which is one of the most abundant fish species in the bone assemblage, was probably caught with hook and line fishing. To investigate the fishhooks' field of application, a morphological and morphometric study was performed on 384 available hooks. Two sets of replicas made of four selected original fishhooks were submitted to a strength test. A breakage study of the incomplete hooks in comparison with the strength-tested hooks was carried out in order to distinguish fresh breaks from dry breaks. It seems that a certain morphology for fishhooks was preferred at Ajvide, indicating they were produced by skilled craftsmen for special usage. The strength test showed that the hooks had a weight bearing capacity more than the average size of cod caught at Ajvide. Using results of these tests, we predicted that the mean breaking strength of 46 intact Ajvide hooks was 96.6 ± 26.1 (s.d.) Newtons (equivalent to 9.85 ± 2.7 kg). The design of fishhooks changed somewhat over time, being slightly larger in the oldest layers of the site. The breakage patterns of the hooks show that the bow was the most common area of breakage. The design and weight bearing capacity of the hooks point to a specialized cod fishery from boats in deep water.  相似文献

中国古墨与现代墨元素成分研究   总被引:1,自引:1,他引:0  
对中国古墨(汉墨、明墨与清墨)与不同产地的现代墨元素成分作了对比分析。用离子背散射测定墨中常量元素C、N、O的含量,用质子激发X荧光法测定微量元素K、Ca、Ti、Cu、Fe等10种元素的含量。实验结果表明,古墨中微量元素K、Ca的含量比现代徽墨、沪墨高10倍以上,而现代徽墨与沪墨中元素N和An的含量也有明显的差别。  相似文献
