俞伟超考古学思想历程可以分为三个阶段,马克思主义考古学解释体系的初步探索;考古学文化与族群关系的文献与实物的二重证据推定;考古学文化遗存的技术、社会和观念的三重解读以及以此为方法论核心的考古学新体系的建立。 相似文献

科默·V.伍德沃德在美国是享有盛誉的南部史专家,同时也是一位非常活跃的社会活动家。在长期的学术实践中他形成了注重史学的社会功能、强调历史发展的非连续性和善用反讽的史学研究风格。他以自己对美国南部历史与现实的深切关怀,积极推动了南部史的研究。其贡献既表现在对新的史学领域和问题的开拓,也体现在围绕他的著述所展开的学术商榷、学术批评中,以及由此而形成的良性的学术研究氛围上。 相似文献

The development of new, gentler methods for the conservation of Old Master paintings, with an emphasis on the removal or thinning of deteriorated varnish, is of high priority. In the course of the deterioration process, oxidative attacks lead to progressive formation of carboxylic acid groups, while many ester bondings are expected to be weakened. A stable RbOH polyethylene glycol complex was a promising tool to react with these moieties and to successfully break down the polymeric varnish layer. The remnants were easily wiped off mechanically. Control studies employing 86RbOH and 14C polyacrylate showed the complete absence of residual cleansing components on the paint surface. 相似文献

由于魏晋南北朝之时史书关于西域记载多有谬误,所以致使研究本时期的西域交通时困难重重。通过具体分析,我们不难看出此处对于"权于摩国"和"于摩国"的记载是有问题的。本文所讨论的"权于摩国"和"于摩国"就是此时期史书因记载情况不同,造成混乱的反映之一,笔者试图通过文献中关于具体路线和里数的甄别,论证出"权于摩国"和"于摩国"在历史记载中不应该被混谈成一国,而是两个小国。 相似文献

In order to interpret strontium and oxygen isotope values in Neolithic human skeletons analysed previously, we begin to map the biologically available strontium, carbon and oxygen isotopic signatures of prehistoric southern Germany by analysing tooth enamel of pigs from archaeological sites distributed around the region. The mapping shows a marked upland–lowland difference in biologically available 87 Sr/ 86 Sr values, ranging between 0.7086 and 0.7103 in the sedimentary lowlands, and from 0.710 to as high as 0.722 in the crystalline uplands of the Odenwald, the Black Forest and the Bavarian Forest. In addition, carbon isotopes in the carbonate fraction of pig enamel were generally about 1–2 more enriched in 13 C in the uplands. Despite the expected depletion of 18 O with altitude, oxygen isotopes in pig enamel showed little correlation with site altitude, although for pig samples not older than the Iron Age there was some geographical correlation withδ18O patterns in modern precipitation. 相似文献

探索和研究表明,岩画断代问题仍然是困扰岩画研究的难题之一,其主要原因是岩画本身不能够提供可供断代的直接依据。本文综述了目前岩画断代研究中经常使用的自然科学和考古学方法及其存在的问题,提出应用AMS14C是今后研究我国岩绘画断代问题的首选方法,解决岩刻画的断代问题则主要有赖于微腐蚀方法。 相似文献

It is now three decades since Waterbolk introduced evaluation criteria to 14C chronology. Despite this, and other subsequent attempts to introduce quality control in the use of 14C data, no systematic procedure has been adopted by the archaeological community. As a result, our databases may be significantly weakened by questionable dates and/or questionable associations between dated samples and the archaeological phenomena they are intended to represent. As the use of chronometric data in general becomes more ambitious, we must pause and assess how reliable these data are. Here, we forward a set of evaluation criteria which take into account archaeological (e.g. associational, stratigraphic) and chronometric (e.g. pre-treatment and measurement) criteria. We intend to use such criteria to evaluate a large 14C dataset we have assembled to investigate Late Glacial settlement in Europe, the Near East and North Africa, supported by the Leverhulme Trust. We suggest that the procedure presented here may at least form the basis of the development of more rigorous, scientific use of 14C dates. 相似文献

This article examines the effect of C.S. Lewis's Irish background on his work. It attempts to contradict the assumption that this Belfast-born writer should be included in the English and not the Irish canon. It emphasises that Lewis saw himself as Irish, was seen by others as Irish, and that his Irish background, contrary to what some have written, was important to him throughout his lifetime. It goes on to demonstrate the ways in which his work was influenced by his youth in Ireland and by the Irish mythology that he loved. Furthermore, this article maintains that, as a child of pre-partition Ireland with roots throughout the island, Lewis was influenced by the country as a whole, not just his native Ulster. Finally, it attempts to understand why Lewis, a proud Irishman, did not do more to promote himself as an Irish writer. 相似文献

不论是修武县2006年发现的1956年续修的《韩文公门谱》,还是修武出土的与韩愈有关的5块石碑,都是修武韩氏伪造的,伪造年代的上限为辛亥革命,下限为1956年。之所以伪造《门谱》和石碑,可能是修武韩氏为了能够达到恢复他们韩愈后裔的称号,并纠正乾隆年以来"修武韩氏永不承袭"圣旨错误的目的。 相似文献
