"文革"中的知识青年上山下乡运动研究述评   总被引:3,自引:0,他引:3  
"文革"中的知青上山下乡运动是当代中国的重大事件之一.中外学者对这场运动进行了深入的探讨研究,取得了不少成果,发表了一批论文及专著,整理和公布了许多资料,目前在许多问题上已达成共识,与此同时也存在很大分歧,如关于"文革"中的知识青年上山下乡运动的基本动因问题、历史进程及其评价问题,对知青"返城风"及上山下乡运动终止原因等等,这些都有待研究者进行深入细致的研究.此外,在研究中还存在资料收集困难、研究力量薄弱、研究方法单一等困难与不足.  相似文献

盘庚迁都新议   总被引:1,自引:0,他引:1  
李民 《史学月刊》2001,(2):16-21
盘庚迁殷,以往大多数学者认为是自奄迁于今之安阳洹南之殷墟,即今之小屯村一带.然而在今之洹南的考古发掘中,很难找到盘庚、小辛、小乙三王时期的文化遗存和遗物.随着考古发掘的扩大和发展,我们认为,盘庚始迁为漳南洹北的殷墟,历经小辛、小乙时期,至武丁时,都城稍稍南移,遂移至今洹南殷墟.盘庚始迁之漳南洹北,文献上称之为漳南之商丘,又可称亳、称殷.它与洹南之殷墟合则称之为殷(后世称之为殷墟),析则分别称亳与殷.由于盘庚、小辛、小乙居洹北仅二十多年,析称的史实遂被“二百七十三年更不徙都“的记载所湮没,致使人们忽略了盘庚始迁的这段历史.  相似文献

Voltammetry of microparticles using a paraffin‐impregnated graphite electrode (VMP/PIGE) was applied as a very local and non‐invasive analytical technique in order to investigate the presence of remains of metallic plating on two ferrous and one cuprous artefact from the medieval period. The analyses have been performed locally and selectively on regions presenting particular features, such as texture, cohesion and colour differences. The results confirm local differences in chemical composition, leading to conclusions about the presence of metallic plating on these artefacts.  相似文献

The technique of oil painting was introduced to Iran via a cultural exchange with Europe in the Safavid period (ad 1501–1736). Since the first attempt at scientific conservation of wall paintings in Iran in the 1960s, the nature of green pigment used in Persian wall paintings has not been clear, although work on contemporary miniature paintings has identified malachite and verdigris. PLM, FT–IR, SEM/EDX, GC–MS and the study of contemporary historical treatises of the Safavid period were the main tools used in the present study to identify the green pigments in Persian (oil‐based) wall paintings. Eight samples taken from the two famous Safavid buildings, Chehel Sotoon Palace and the Sukias House in Isfahan, were analysed. Here, the identification of copper‐based pigment and of verdigris in oil as oleate amends the existing knowledge of the green pigment used in these paintings. It also suggests that oleate was introduced to Persian artists via the European influence on Persian painting as a result of cultural exchange in the Safavid period, when the technique of Persian painting changed from tempera to oil painting. However, as verdigris in oil and resin can appear as oleate over time, it is unknown whether the Persian artists did this deliberately or accidentally.  相似文献

2015尼泊尔地震对加德满都谷地的世界文化遗产造成不可估量的损失。为了探究谷地文化遗产震害整体分布特征,对谷地世界文化遗产建筑的震害状况开展实地调查,划分了三类文化遗产震害等级标准,形成了六处世界文化遗产的震害图并对其进行统计分析,加德满都、帕坦和巴德岗三处杜巴广场震后保存基本完好的文化遗产建筑占各自总数的39.5%、53.3%、50%,斯瓦扬布纳特寺、昌谷纳拉扬寺和博达哈大佛塔主体保存基本完好,附属建筑不同程度地破坏。加德满都、帕坦和巴德岗三处杜巴广场地层的松软沉积层放大地震效应使建筑严重破坏,斯瓦扬布纳特寺、昌谷纳拉扬寺震害主要受地形特征影响。考察成果为我国同类遗产建筑的抗震防护提供参考。  相似文献

Within Iran, there is little archaeological evidence for relationships between newly arrived Early Trans-Caucasian (ETC) or Kura-Araxes settlers and earlier inhabitants and contact with neighbouring cultures, or for their apparently abrupt end. Based on the evidence, the Iranian Kura-Araxes was not a simple ‘copy' of the Caucasian Kura-Araxes package. Ceramic traditions show local peculiarities, and all are elements suggesting that the Kura-Araxes traditions went through processes of adaptation, change and re-elaboration according to local tastes and technologies. In this study, an archaeometric approach to ceramics in the Kolyaei Plain of central Zagros contributes to the discussion of contact and exchange between indigenous communities and several cultural spheres of influence on the Early Bronze Age (beginning in the fourth millennium bce ). Morphological data, as well as the mineralogical and chemical composition of ceramics, were applied to determine the major and trace elements of the pottery shards. Based on the trace element profiles, it can be suggested that all the pottery shards are in the same group and they strongly are local products. The ceramic provenance indicates the same patterns of material interactions during the ETC or Kura-Araxes in all the sites within the Kolyaei Plain.  相似文献

The study analyses the chemical composition of 57 glass samples from 40 beads discovered at 20 archaeological sites in Poland. The beads are dated to Hallstatt C–Early La Tène periods (c.800/750–260/250 bce ). Analyses were carried out using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Two groups were distinguished among the glasses based on the MgO/K2O ratio: high-magnesium glass (HMG), five samples; and low-magnesium glass (LMG), 52 samples. The former were melted with halophyte plant ash, the second with mineral soda. These glasses were produced in the Eastern Mediterranean (more likely in Mesopotamia or Syro-Palestine than in Egypt) and transported in the form of semi-products to secondary glass workshops in Europe. Some of the white opaque glass was coloured and opacified in Europe.  相似文献

This paper focuses on Kochav-Yair and Oranit, two localities that exemplify the Israeli Suburban Settlement phenomenon. With the first being developed by a selective group of families and the latter by a single private entrepreneur, yet both with the full support of the state, they represent the selective privatisation of the national settlement project during the 1980s. Examining the geopolitical, social and economic interests that accompanied their development, this paper illustrates how both projects incorporated the upper-middle-class bourgeoisie in the national territorial effort along the border with the occupied West-Bank (the Green-Line). Analysing the planning and construction process of both case studies, as well as their spatial characteristics, this paper explains how the upwardly middle-class and its contractors were granted substantial planning rights. Consequently, enabling them to influence the production of space while promoting a new local suburban typology that is based on better living standards, private family life and a distinctive isolated community. Therefore, this paper illustrates the Suburban Settlement typology as an outcome of the bourgeoisification of the Green-Line, which domesticated the former frontier area and enabled its inclusion in the greater national consensus.  相似文献

中国新史学中最常见的两种历史研究方式是科学实证与文化阐释,前者旨在建立历史事实之真或寻求历史演变之理,后者则以探寻历史之意义或彰显切实之史识为目标,此二者可谓中国新史学之"双轨"。中国新史学正是沿此"双轨"向前发展的。从新史学之"双轨"着眼,并依据"新异性的标准",中国新史学界应有"八大家",他们分别是:梁启超、王国维、陈寅恪、胡适、顾颉刚、傅斯年、郭沫若和钱穆。科学实证与文化阐释,这两种不同的历史研究取径,展示了中国新史学研究的多元面相,二者之间是相互融通的,并无根本性的冲突与对垒,其在治史观念与方法上亦可做到相互补益,相得益彰。许冠三在《新史学九十年》中因陷入"科学"迷思的褊狭"新史学观",以科学实证拒斥文化阐释,故而未能将钱穆基于"文化"视角来研究历史的文化史学视为新史学。钱穆的新史学特质主要表现为:在继承中国传统史学遗产之基础上,注重历史研究主体与客体的统一,以文化为本位,以阐释为取径,其典型表现是"以士释史";以中国为立场,注重探寻本国历史文化之意义,探求与本国历史文化相符合之史识,强调历史学的经世致用功能。钱穆的新史学观与后现代主义在批判科学主义历史学、反对文化一元论和西方中心主义历史观等方面多有契合之处,但其以"于客观中求实证"为基础的历史认识论与走向历史虚无主义的后现代主义有着本质的区别。  相似文献

黄河中下游地区40余处遗址的400多座二层台墓资料显示,生土二层台墓的数量在仰韶中晚期以前较熟土台墓多,龙山时代式微。该变化的背后是棺椁的逐渐成熟,生土台墓中小部分带有盖板或原始棺椁,同时熟土台并非判断墓葬带有棺椁的充要条件。通过生土台高度和墓葬深度的二元变量分析,墓葬开挖时预留生土台并未考虑稳固墓室,而应该与构建殓尸空间(或椁室)、进行一系列丧葬活动有关,在台面上放置随葬品的情况存在一定的时空差异。二层台墓的分布具有集中埋葬的倾向,采用二层台墓的群体并无明显的性别和死亡年龄指向,从仰韶中期以来,其所代表的社会群体占据着更为优越的社会财富。  相似文献
