Offa’s Dyke is one of the largest and best known, if rather less well understood, field monuments in Britain. Despite this, there have been very few primary studies of it. This article makes a critical examination of the principal bodies of work dealing with the dyke. It argues that in many respects our knowledge is less certain than is usually believed. In particular it discusses the time and labour necessary for the construction of the earthwork and it is suggested that it could have been constructed much more quickly, and with a much smaller workforce, than is generally supposed. More fundamentally, the purpose and function of Offa’s Dyke are considered, and it is argued that, in addition to any practical utility it may have had, the earthwork had important ideological significances that until recently have been largely neglected. Specifically, it is argued that the dyke was a manifestation of eighth-century Mercian royal ideology, intended to consolidate the power of the Mercian kingship, in the west midlands in particular and southern England more generally. 相似文献

During the Chinese War of Resistance against Japanese Aggression, the Chinese Communist Party (CCP) made great progress in its cultivation of cadres. The favorable environment of the National United Front made it possible for the CCP to successfully train a large number of cadres with intellectual backgrounds while continuously using and promoting those who came from worker or peasant backgrounds. By so doing, the CCP raised the quality of its cadres. The CCP’s cultivation of its cadres during the War of Resistance was a systematic undertaking, with interrelated and mutually reinforcing components of education, training, examination, criticism, and self-criticism. Based on cadre self-consciousness and training, a regularized yet not rigid process of cadre cultivation was established. During the same period, the CCP also launched a rectification campaign (Zhengfeng yundong) to further unify and transform the Party. This important movement also left a deep mark on the cultivation of Communist cadres. 相似文献

It has been difficult to infer behaviours related to anterior tooth use in fossil hominids owing to a lack of broad‐based comparative studies of the relationships between front tooth use and craniodental features in modern humans. In this study, we seek to establish such a neontological baseline by exploring aspects of craniodental form among populations of recent humans that are inferred to have differed in habitual levels of ingestive and paramasticatory processing using the incisors. Morphometric data are compared among samples from three human populations: Aleutian Islanders (n=25); Arikara from the Mobridge Site, SD (n=19); and a late Woodland Bluff group from Jersey County, IL (n=24). Data for various biomechanically relevant dimensions were collected using standard callipers, while three‐dimensional (3D) coordinate data for 28 cranial landmarks were recorded using a video‐based image analysis system. These data indicate that several aspects of cranial form thought to influence the efficiency of force production on the incisors differ among the examined groups, including the positions and size of the primary masticatory muscles and the position of the dentition. For most dimensions, the Aleut sample exhibits the most mechanically advantageous configuration, the Illinois Bluff group the least advantageous configuration, while the Arikara are intermediate in form. This pattern corresponds to differences in the intensity of incisor loading among these groups, as inferred from both ethnographic reports and incisor microwear data. These results, therefore, suggest that cranial form in humans varies with subsistence‐related differences in masticatory force production and that quantitative studies of masticatory system configuration may provide useful information for studies of hominid palaeobiology.

陕西安康紫阳北五省会馆壁画颜料分析研究 总被引:3,自引:3,他引:0
陕西安康紫阳北五省会馆壁画是目前陕西省境内发现的最大的一处建筑壁画,为了解其颜料组成,本工作采用X射线荧光、偏光显微镜、X射线衍射、激光显微拉曼光谱及扫描电镜能谱分析相结合的分析方法,对颜料样品进行了分析。结果表明,北五省会馆壁画除正殿发现一处红色染料外,其他均为无机颜料;红色颜料主要是铅丹、朱砂、铁红;绿色颜料为氯铜矿、石绿、斜氯铜矿;蓝色颜料的主要成分是普鲁士蓝、smalt、石青;黄色颜料为雌黄、铁黄;褐色颜料的主要成分是铁红及铅丹的变色产物二氧化铅;黑色为炭黑;白色颜料主要是铅白,且多使用铅白作为调色颜料。研究结果对于了解清代民间壁画的制作工艺,丰富对陕西建筑壁画的认识具有重要意义。 相似文献

基于富集在铜料中而保留其母矿信息的元素可以用于示踪青铜器的矿料来源,为了解郑韩故城青铜器的矿料来源,利用ICP-AES方法对郑韩故城出土东周时期青铜器的微量元素进行了检测。结果显示,21个青铜器样品微量元素特征具有相对一致性,推测可能具有相同的原料来源。与小双桥遗址出土青铜器的微量元素特征进行对比,二者存在明显的差异,说明从商代中期到春秋战国时期,这一地区的原料来源发生了改变。研究结果可为研究东周时期这一地区铜业发展状况提供线索。 相似文献
