ABSTRACT

In December 1984, a private Japanese academic organization, the “Nanjing Incident Research Committee” (Nankin Jiken Chōsa Kenkyūkai), sent a survey team to visit Nanjing, with the aim of obtaining more evidence on the Nanjing Massacre to counter the internal debate within Japan. Through the coordination by the “Office of the Leading Team on History, Museums and Monuments for the Nanjing Massacre” during the visit, the survey team was able not only to gather historical materials, meet with survivors, and tour historical sites, but also to engage in exchanges with Nanjing researchers and students of Nanjing University. This visit to Nanjing further publicized Japan’s internal debate on the Nanjing Massacre in China, while also representing an unprecedented effort for collaboration between China and Japan in research on the Nanjing Massacre.  相似文献

In this article, a Simulink simulation block with the finite element function is developed on the basis of S-function and implemented as the numerical substructure of real-time dynamic hybrid testing. Thereby, a real-time dynamic hybrid testing system coupling finite element calculation and shaking table testing is achieved. Using the developed system, a shear frame mounted on the soil foundation is tested, in which the shear frame is simulated as the physical model and the foundation is simulated as the finite element model with 132 degrees of freedom. Several cases of the dynamic behavior of soil-structure interaction are studied.  相似文献

Temporary consolidation is widely used to protect delicate artefacts or other fragile relics in art conservation. Although cyclododecane is extensively accepted, the safety‐related issues have become an increasing concern and its short working time is always annoying. Inspired by its low melting point, polar structure, well‐established safety profile, easy local availability and low cost, we propose menthol as a new temporary consolidant on the new excavation site of Qin Shihuang's Terracotta Army. In this paper, we offer a preliminarily exploration of the kinetics of menthol sublimation on two different matrices, its residue after volatilization, its penetrability and distribution in simulated terracotta samples, as well as other important properties in the laboratory. The results obtained from these tests reveal that the sublimation of menthol can be a zero‐ or a first‐order process, depending on the porosity of the matrices, and its best operational temperature resides in the range of 60–80°C. Finally, two field cases at the archaeological site of Qin Shihuang's Terracotta Army are presented to show that menthol is a very effective temporary consolidant.  相似文献

故宫古建筑内温湿度问题初探   总被引:1,自引:1,他引:0  
博物馆的环境应当相对稳定且有益于文物的保存。故宫博物院作为古建筑博物馆,其特殊性在于古建筑本身也是文物,虽然自身条件较差,但又不能随意改变其外观和结构,导致其保存环境往往不够理想。在研究中论述了故宫古建筑的环境特点,结合在古建筑内文物环境监测和控制方面的若干问题进行有益的探讨,对原状陈列的古建筑温湿度调控的应用效果进行了分析和评估,指出了存在的问题,并提出了对古建筑中环境控制的思考。采用密封性能优良的展柜配合适当的调湿材料可以很好地稳定相对湿度,减少温度变化对相对湿度造成的影响,这是当前国际上文物微环境控制的一个发展方向。  相似文献

本文运用现代纺织科学的检测手段,分析了故宫博物院收藏的两件“羽毛纱”样品的组织结构和各项物理指标(织物单位面积质量、织物密度、纱线线密度、纱线捻度和捻度系数)及其织造方法,找到了同样织法的两块织物,存在不同面料风格的真正原因。古人通过巧妙的织造方法,充分发挥纺织原料各自的优点,织造出满足不同穿着目的的面料。  相似文献

由明矾和胶料配制而成的胶矾水,是书画绘制、装裱和修复过程中经常使用的材料。胶矾水具有防腐、固色和增加机械力度等功能,但对纸质文物的耐久性有一定的影响。本研究选用宣纸、桑皮纸和连史纸等代表性的传统手工制纸,在它们的表面分别涂敷不同浓度的胶矾水,经干热老化后,对比分析它们的酸碱度、白度、耐折度和抗张强度的变化,揭示胶矾水对这几种手工纸张性能的影响,进而探讨其影响机理。研究结果表明,胶矾水将增加纸张的酸度、降低纸张的白度,明胶水能提升纸张的机械强度,而不同浓度明矾对纸张机械强度的影响存在差异。  相似文献

We have investigated change in subsistence during the transition to agriculture in the site of Jiahu, Henan Province, China, using stable isotopic analysis of collagen and apatite in human bones. Millet agriculture is well documented at drier high latitudes of the Yellow River Valley, while rice agriculture predominated at wetter lower latitudes of the Yangtze Valley region. The early Neolithic site of Jiahu lies near the boundary between the drier north and wetter south. Archaeobotanical evidence shows that rice was a significant component of diet at Jiahu, but its δ13C value is similar to that of other foods, and therefore cannot be conclusively identified by carbon isotope analysis. Foxtail and broomcorn millets are the only C4 crops known for the Chinese Neolithic. Because of their high δ13C values, their consumption can be evaluated by stable carbon isotope analysis of human bone. Collagen reflects mainly the δ13C value of dietary protein, and apatite accurately records that of the whole diet. Isotopic analysis of 15 well-preserved samples from three periods shows that collagen δ13C values were very low for almost all individuals, suggesting C3-based foods dominated their diets. However, apatite carbonate δ13C values and δ13C spacing between collagen and apatite (Δ13Cap-co) indicate that millet may have been a minor component of the diet in this region. Individuals, who consumed the smallest amounts of animal protein, as indicated by low δ15N, generally had the highest apatite δ13C values. Archaeobotanical evidence for millet at Jiahu is needed to support this interpretation.  相似文献

本文探讨了有关唐代越窑青瓷刻划花的若干问题。作者以有明确纪年的唐代越窑刻划花青瓷以及相关的同一时期的有代表性的墓葬、窑址、遗址、沉船中发现的越窑刻划花青瓷为依据,总结了唐代此类瓷器工艺的演变规律和技法特征,分析了其与金银器的关系问题,并推测出此类瓷属于对外贸易的外销产品。  相似文献

明万历年间所修<永泰张氏宗谱>,对研究南宋著名词人张元干具有重要的史料价值.二十世纪八十年代,福州市文化局的曾意丹先生和福州市文物管理委员会的官桂铨先生曾先后撰文,披露过宗谱的有关内容,曾先生撰有<张元干生平及其思想渊源考辨>①,据谱中所收张元干之子张竑墓志铭,考出张元干的卒年是绍兴三十一年(1161).官先生所撰<词人张元干世系>②,则据宗谱资料,弄清了一向混沌的张元干家世.十几年前我撰写<张元干年谱>时,主要参考的就是官先生文中提供的宗谱资料,而未能见到宗谱原书,谱中很多珍贵的资料未能采用.1989年<张元干年谱>在南京出版社出版后,我才与官先生取得联系,他慷慨地将<永泰张氏宗谱>全谱复印一份寄赠给我.我如获至宝,一直珍藏至今.  相似文献
