古代(战国)丝织品的降解特征初探 总被引:1,自引:0,他引:1
为深入了解研究古丝绸的降解特征,对新鲜丝绸和古丝绸进行对比研究,采用了包括扫描电子显微镜、红外光谱仪、X-射线衍射仪、差热分析仪等现代仪器分析方法,从宏观到微观对古丝织品进行了多角度、多层次的综合分析。结果表明,古代丝绸在复杂的地下环境下,受酸、碱、盐和微生物的综合作用,丝绸的宏观形貌、分子结构发生了明显变化。古丝绸的质地也不再有蚕茧那么致密均匀,丝蛋白的构像发生了变化,肽键断裂,碳碳键断裂,结晶度变小,热稳定性变差,使之失去了原有的强度。了解这些降解特征对采取正确的保存保护古丝绸具有重要的意义。 相似文献

试论中国新兴的人工旅游资源 总被引:1,自引:0,他引:1
以1958年美国兴建洛杉矶迪尼斯乐园为标帜,国际上人工旅游资源正迅速崛起。近十年来我国新兴的人工旅游资源不断涌现,主要有:(1)微缩景观公园;(2)影视拍摄基地;(3)游乐园及野生动物园;(4)仿古街及仿古园林;(5)专题博物馆与碑林;(6)旅游节日等。我国新兴的人工旅游资源在地理分布上集中在东部沿海地区,具有求知、求新、求乐、求奇的时代特征,意味着我国旅游形式从单纯的游览观光开始向游客参与和消遣型转变。一些人工旅游资源如深圳\"锦绣中华\"公园,无锡\"唐城\"、北京世界公园、哈尔滨冰灯艺术节等取得良好的社会效益和经济效益。今后对人工旅游资源的发展应保持宏观控制与正确引导。 相似文献

Accurate determination of sex in skeletal human samples is very important in anthropological and demographic studies. Recently, Loth and Henneberg have suggested that a new osteological criterion on the mandible, the mandibular ramus posterior flexure (MRPF) had a high sex discriminating effectiveness. A preliminary test applied to a few hominid mandibles )including Australopithecines, Homo erectus, Neanderthals and Upper palaeolithic hominids) apparently confirmed the high reliability of the MRPF as a sex indicator ‘over time and through palaeospecies’. As the pelvis is commonly considered as providing the most significant criteria that allows the establishment of skeletal sexual dimorphism of adults, the present paper evaluates this mandibular feature on a few additional palaeolithic hominids (i.e. Neanderthals and Early Modern Humans) for whom a gender estimation was known based upon the pelvis. This analysis was conducted on the original material and its results appear in contradiction with those of the previous studies made by Loth and Henneberg. A reconsideration of the visual assessment of MRPF as a sex indicator in Homo sapiens fossil hominids is therefore suggested. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

The article offers a study of the theological method of Henry Dodwell, the most distinguished British savant of the late Stuart period and a leading figure in the Non-Juring movement. The study takes the form of arguments for the extension of the contemporary dispute between the Ancients and Moderns, in its historiographical dimension, into the field of divinity; for substantial modification of the claims made in discussions of the dispute about the inherent conflict between the Renaissance's desire for revivification of the past and its historical scholarship; and for reconsideration of the relationship between 17th century critical scholarship and the Enlightenment. 相似文献

Previous studies propose that the Yangtze River is the geographic boundary separating northern and southern Chinese populations. In order to test this hypothesis, 19 Neolithic and 15 Modern human cranial samples from north of the Qinling Mountain Range, south of the Yangtze River and in between were chosen for morphometric analysis. Our results indicate that cranial variation exists in Holocene Neolithic and Modern northern and southern Chinese. In the Neolithic sample, the northern Chinese crania are characterised by greater upper face height and orbit height, while the southern Chinese skulls are depicted by a wider nose. The morphology of the crania between the Qinling Mountain range and the Yangtze River feature a mosaic of characters that suggest affiliation with both north and south groups. In the Modern day sample, northern crania are characterised by a broad and wide face, and a tall nose. From the Neolithic to Modern day, a series of microevolutionary processes that apply to both the northern and southern samples can be discerned. Overall, the head gets lower, the face and nose become narrower and the orbits tend to be narrower and higher. Our results support the suggestion that the Qinling Mountain Range and the Yangtze River represent a natural barrier to the movement of Chinese populations. Climatic variation and the transition to an agricultural lifestyle are proposed as the primary factors influencing human craniofacial morphologies. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

This article argues that use of the concept of ‘political religion’ to describe the radicalized political movements of the twentieth century has again gained currency in recent years as a result of the collapse of the Soviet Union as well as the global upsurge of religiously inspired violence and that research with respect to religion proper – what religion is, its role in public life, its evolving reception by ‘insiders’ and ‘outsiders’ – can advance the discussion. The article subsequently offers the author's own research as evidence of the concept's applicability to the case of National Socialism. Analysis focuses, specifically, on a movement in nineteenth century Germany to develop a secular system of ethics, a project that eventually led, ironically and tragically, to the emergence of a new faith in a absolutized ‘collective will’ as the transcendent source of all moral values. The National Socialist movement subsequently co-opted this article of faith, the article argues, by transforming Hitler into a holy medium for the salvific dictates of what became, by the early 1930s, an unimpeachable ‘Volkswille.’ 相似文献

In early 1969 the new US President, Richard Nixon, suggested the expansion of allied political consultation, as well as the setting up of a North Atlantic Treaty Organization (NATO) committee which would deal with environmental problems. The Americans stressed that their proposal did not involve merely the technical aspects of environmental protection, but also the need for modern governance to evolve in order to safeguard the ‘quality of life’, a prime aspect affecting the legitimisation of the political and social systems. The US proposal was not received enthusiastically by the allies, who had little desire for radical changes, and did not regard this as a proper subject for the alliance; some even feared that a NATO role in environmental questions might mask a US disengagement from European security, especially during an era of détente. However, after making sure that the new committee would be fully under the control of the Council (in accordance with NATO's inter-governmental character), the allies finally agreed to its creation. The NATO discussions on the Committee on the Challenges of Modern Society (CCMS) point to the emergence of a new, more complex international agenda, and raise interesting questions regarding transatlantic relations during an era of wider transitions. 相似文献
