咸阳地区出土汉代彩绘陶器表面颜料的科学研究

为了掌握陕西省内陶质彩绘文物的基本情况、受损现状及保护现状等基础数据,我们开展了“陕西省陶质彩绘文物调查研究项目”。通过对咸阳地区汉景帝阳陵、杨家湾汉墓、汉武帝茂陵、窑店三义村等大型汉代墓葬出土彩绘陶器表面颜料进行研究,从颜料物质成分、彩绘工艺等方面进行了科学检测和分析,为彩绘陶器的保护修复提供了依据。     

eBay and research in historical geography

The electronic trading forum eBay presents fascinating but under-examined possibilities for research in historical geography. With literally millions of items for sale and millions of users participating in on-line auctions there seems little limit to what one might find. In this essay, three authors briefly trace the history of auctions and of eBay, before explaining how eBay works, and then describing some of the ways that buying (or not buying) research materials on eBay has changed the ways that we think about our work. We further explore some of the implications—empirical, theoretical, methodological and ethical—that the availability of such items to the highest bidder presents, address some of the consequences for the socially constructed and place-specific nature of value that on-line auctioning reveals, and ponder some of the implications of this for contemporary consumption.     

The Relationship Between Teaching and Research in Australian Geography

This paper considers how higher education geography is a discipline that can make a significant contribution to addressing inequality and engaging with the agenda for social change. It adopts the view that the teaching of geography can promote social transformation through the development of knowledge, skills and values in students that encourage social justice and equity. The paper explores how teaching about social transformation is closely interlinked with teaching for social transformation and considers some of the pedagogical approaches that might be used to achieve these. It considers how the lack of diversity of higher education geography teachers impacts on these issues before moving on to consider how the nature of different higher education systems supports or constrains geographers' abilities to teach for social transformation. Finally, the paper ends by asking individuals and geography departments to consider their commitment to teaching for social transformation.     

电工实训、实习课中教学方法的探讨

高等职业院校电类专业的电工生产实习是在学生通过进校学习一年或两年文化课和理论课后,对电类专业有了一定的了解和具有了一定的专业理论知识,如何实施电类专业技能的教学。怎样才能使这些从未接触电类技能的学生能较好得掌握这门技能,本人在长期的电212生产实习教学过程中,认为启发式教学法是一种行之有效的教学方法。     

河南博物院藏《唐人写经》卷的纸张研究

河南博物院藏《唐人写经》卷,纸张确认为麻纤维。纸张厚度不均匀,属于较厚的麻纸。水平帘纹很宽,因此判断所用模子不规整。纸张渗透性好,说明纸张原始施胶技术上乘。纸张尺寸符合唐代宗教手稿用纸习惯,基本符合8世纪的宗教手稿情况。     

论简帛的文献学研究价值

一个世纪以来,发现的简帛文献已达约22万枚(件),总共约700万字。它们具有极强的文献真实性,在目录学、版本学、校勘学、辨伪学、古籍文意解读等方面,都具有十分重大的研究价值。我们应该高度重视并深入开展对简帛文献的研究,以利于古文献学的发展。     

Virtual Development and Virtual Geographies: Using the Internet to teach interactive distance courses in the global South

This paper evaluates the delivery and learning outcomes of an interactive postgraduate geography and development MSc programme taught partially over the Internet, to students living in some of the most connectivity-poor regions of the world. It focuses particularly on the experiences of course developers, tutors and students, with the distance strand of a Master's Programme pioneered by Royal Holloway, University of London, and IW:LEARN (International Waters Learning Exchange and Resource Network), a UNDP-implemented project of the Global Environment Facility. Issues of design and implementation are discussed, with particular reference to pedagogical and financial questions and the considerable technical and personnel difficulties encountered. Comparability of experience between distance and residential students forms a central concern.     

南阳麒麟岗西汉墓中出土的后石家河文化玉鹰

1989年南阳麒麟岗西汉墓M8出土了一件后石家河文化时期减地阳线纹的玉鹰残件.根据其他遗址出土或传世的类似形制遗物,对这件器物进行研究性复原.复原后发现该件玉鹰为目前已出土的后石家河文化时期尺寸最大的圆雕玉器,为探讨后石家河文化时期的玉器传播提供了新的资料.

Recovery of a lost wall painting at the Etruscan Tomb of the Blue Demons in Tarquinia (Viterbo,Italy) by multispectral reflectometry and UV fluorescence imaging

This paper presents the results of a multispectral reflectometry and ultraviolet (UV) fluorescence study on the entrance wall of the Tomb of the Blue Demons in the Necropolis of Monterozzi (450–430 bc ) in Tarquinia (Viterbo, Italy), which is a UNESCO site. The technique is based on the acquisition of a multispectral set ranging from 10 to 25 images, acquired at wavelengths between 370 and 1120 nm, with a spectral width of 50 nm per image, using both halogen lamps for visible and infrared images and high‐purity UV diodes for fluorescence. Blind‐source separation algorithms were then applied to the whole image set to extract from the resulting images the details not otherwise visible in the single spectral images. The multispectral technique presented was tested and improved upon over the last decade on ancient Etruscan and Roman wall paintings and, because of its quickness and cost‐effectiveness, it can now be proposed as a powerful tool for the study of poorly conserved archaeological wall paintings and a preliminary diagnostic survey before any future conservation intervention on them.
