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

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

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

商前期青铜斝的制模工艺初步研究   总被引:1,自引:0,他引:1  
制模是青铜铸造工艺的第一道工序,也是关键工艺之一,其重要性不言而喻。而文献记载的缺乏,考古实物资料的限制,严重影响了学界对陶模制作工艺的认识。近年来,我们通过对大量青铜实物的细致考察,发现大多青铜器上都有明确、整齐的范缝。为研究夏商之际的范铸技术,我们对商前期青铜斝进行了模拟制备,发现分型制模才是其制模工艺的主流,用此种工艺制模更加符合器物上的范铸特征。  相似文献

Abstract

Geological information was first printed in colour on a map in 1820 but serious efforts to print geological maps in multiple colours began in Europe only in the 1840s. Increased geological mapping activity created the need to print more maps by cheaper methods, while general advances in lithographic colour printing provided the means. Better colour registration, transparency, range, permanence and distinctiveness were attained in the 1840s and 1850s by technical innovations and also by new design strategies. Consequently, as printed colour replaced hand colour as the norm, it also influenced the look of the geological map.  相似文献

Edmond Halley made two scientific voyages in the Atlantic Ocean as captain of the HMS Paramore between 1698 and 1700. Following these voyages he published the first map showing lines of equal magnetic declination in 1701. Halley did not reveal how he constructed the map, however, and it remains unknown. In this study, a construction procedure is hypothesized that uses mathematical tools that were available in his day, namely arithmetical averages and Isaac Newton’s method of divided difference for fitting a polynomial curve to data. To enable his map construction, a method is suggested whereby Halley could have created new data to augment the situations where insufficient data were collected.  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.
