为了更好地了解亚浸水漆器的制作工艺及材质,为该类文物修复保护提供科学依据,本工作采用扫描电镜能谱分析、X射线衍射分析、红外光谱分析等技术对出土于陕西长安县明代墓葬一漆棺的制作工艺及主要制作材料进行了分析研究。结果表明,漆棺是按照木胎-纤维-灰层-漆膜-颜料的工序制作的,主要使用材料有麻、粘土类物质、生漆、金及朱砂颜料。漆棺制作工艺及材质与文献记载基本一致,是中国古代漆棺传统工艺制作的典型代表。  相似文献

The rig of the Duyfken 'replica', a reconstruction Dutch jacht of c . 1600 is described. Sail-handling techniques and sailing performance including steering with a whipstaff are also described. Experiments to improve sailing efficiency, some prompted by analysis of contemporary iconography, are discussed.  相似文献

An integrated remote-sensing survey was carried out in Navarino Bay, where in 1827 a battle was fought between the allied British, French and Russian navies and the Turkish-Egyptian fleet. Integration and interpretation of the remote-sensing data has shown the presence of shipwreck remains on the sea-floor and possible shipwrecks buried under the sea-bed. It has also shown that the historical remains are under threat from the heavy anchors of tankers which sink into the sea-bed and, when dragged, dig furrows, thus disintegrating the shipwreck remains. To protect the sites the construction of permanent anchoring systems away from the shipwreck remains is recommended.

In the last few years virtual anthropology has been used to solve different problems that could not be properly addressed using a traditional anthropological approach. Mainly when dealing with mummies or embalmed bodies, the virtual approach is the only solution to carry out a detailed analysis of the skeleton without jeopardizing the integrity of the physical remains.  相似文献

麦积山石窟保存了大量的从后秦到明清时期的雕塑艺术品,通过近期的系统调查,发现除了普通的泥塑工艺以外,还普遍地存在着一种泥塑烘烤工艺,使泥质塑像的表面不同程度地存在着陶质化的现象,这对于古代塑像的工艺研究、文物保护等方面都有重要的意义。  相似文献

Making use of analytical, chemical and mineralogical methods, this paper focuses on the analysis of inclusions in order to address the question of the provenance of prehistoric artefacts excavated in Gura Cheii-Râ?nov Cave (Romania). The study represents the first discovery of bitumen on lithic tools belonging to the Upper and Middle Palaeolithic in Europe. The material was identified through several analytical procedures, such as Fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray fluorescence (EDXRF), inductively coupled plasma atomic emission spectroscopy (ICP-AES), and X-ray diffraction (XRD).  相似文献

The article describes lithic industries of the Upper Paleolithic levels of Kulbulak, Uzbekistan, a key site in southwestern Central Asia based on materials from excavations at several sites in the western and northwestern Pamir– Tien Shan region (Kulbulak, Kyzyl-Alma-2, Dodekatym-2, and Shugnou). A new cultural and technological tradition is introduced, for which the authors suggest the name Kulbulakian. Its distinctive features are the bladelet technique and a microlithic set including backed pieces and triangular microliths. Stages in the evolution of the Kulbulakian tradition are reconstructed: origins, development, peak, and disappearance of the carinated technology. Industries belonging to this tradition have shaped the general appearance of the Upper Paleolithic in the area in question.  相似文献

Chuaria is widespread in Late Precambrian deposits throughout the world. In China it has been found in the Jingeryu Formation of Jixian County, Tianjin, and in its equivalents in eastern China including the Nanfen Formation of Liaoning and Jilin Provinces, and the Liulaobei Formation of Anhui Province. In the latter, Chuaria is associated with the genus Tawuia which Hofmann (in Hofmann & Aitken, 1979) described as algae of undertermined affinity and which is based on material from Canada. The glauconitic sandstone directly resting upon Chuaria-bearing greyish-green shale of the Jingeryu Formation in Jixian County has a K-Ar age of 0.899 Ga. This paper describes C. circularis Walcott, T. dalensis Hofmann and T. sinensis n. sp., and discusses the morphology, biological and taxonomic affinities, and age and geographic distribution of Chuaria. Because of the association of Chuaria and Tawuia in the Mackenzie Mountains, Canada, and also in the area of Shouxian County, Anhui Province, China, it is considered that Chuaria and Tawuia probably have close affinities. According to their general morphology and occurrence, both may be marine planktonic multicellular algae.  相似文献

Two main regression methods have been proposed for using site category information within ground motion prediction equations, these are: (a) joint estimation of the site category coefficients and the magnitude and distance coefficients; or (b) estimation of site category coefficients by using the residuals from the equation derived without considering soil conditions. Method (a) requires each record be assigned a site category whereas for method (b), because it relies on residuals, site information can be missing for some records. This short note finds that if the mean of the transformed distances within each site category is the same then the two methods give the same site coefficients. If, however, these means are significantly different then method (b) can yield incorrect site coefficients.  相似文献
