关于考古出土纸质文物保护利用的若干思考

19世纪末,我国西北地区开始有纸质文物的考古发现,其后纸质文物在多地考古发掘中均见出土.它们品种多、数量大,加工工艺、写印材料独特,时代自汉代至明清,其中的早期文物尤为珍贵.因其出土环境复杂,保护修复工作难以直接借助传统技术和现有科技,特别是潮湿环境和干燥潮湿交替环境下出土纸质文物的保护修复往往遭遇瓶颈.目前学界在科学分析检测、造纸工艺研究、科学信息提取等科学化研究方面取得了一定成就,但对糟朽类文物的病害机理、保护修复技术等研究还远远不够.因此,当务之急是开展本体材质、劣化与粘连机理研究,探究多因素协同作用对本体的长期影响和作用方式,研发新材料与新技术,并致力于探索这类文物的活化利用.     

新疆额敏县出土红铜器的保护与修复

文物修复是一门严谨的学科,随着科学修复技术的快速发展,社会审美观念的变化,选择更好的修复材料（具有可逆性）和方法,是今后文物修复的重要手段,通过这次的修复工作实践,结果表明,不仅复原了红铜大桶的外观形貌特征,而且恢复了原始的红铜色彩及特征,摸索出一套全新的红铜器修复技术和工艺流程。同时对修复理念和多学科交叉应用有了新的领会和提高,也是未来文物修复的研究方向。     

试论数据采集与虚拟修复在大足石刻修复中的应用

文物作为一种不可再生的宝贵资源,其本体上的保护修复工作均需慎之又慎,需遵循国际上规定的“最小干预”及“可逆性”基本原则.为此,虚拟修复成为对文物动手修复时的重要辅助手段.然而,多数文物具有复杂立体结构和色彩,传统的虚拟修复技术难以实现逼真效果.三维激光扫描是近年来飞跃发展的一项高新测绘与信息技术,具有无损、空间精度高、速度快等突出优势,在文物数字留存及相关保护应用中发挥了重要作用.三维激光扫描技术与高清摄影技术相结合,为文物的虚拟修复带来新的契机.本文结合文物虚拟修复基本需求分析,提出了基于三维激光扫描技术的文物虚拟修复关键技术与工作流程,并以国家一号石质文物保护工程——大足石刻宝顶山千手观音造像的保护修复为例,进行了应用实践,综合历史资料和现有数据的分析,实现了三维形态及色彩的虚拟修复.结果表明,基于三维扫描的虚拟修复能够提供更为逼真的三维虚拟修复模型,供修复专家研究参考.     

西汉绛紫绢地“长寿绣”丝绵袍制作工艺考析

笔者对马王堆一号汉墓出土的绛紫绢地“长寿绣”丝绵袍进行了保护修复。为了更好地复原文物,达到适宜展示陈列的状态,在修复之前针对此文物做了材质鉴定、织造工艺、材料老化判断及裁剪工艺等系列研究。在对其制作工艺进行细致、全面的信息采集与数据分析之后发现,这件丝绵袍的裁剪制作工艺与发掘报告所述裁剪缝纫秩序不同,是先刺绣好面料后,再裁剪制衣,证实了马王堆一号汉墓出土曲裾丝绵袍制作工艺的多样性。

干冰清洗技术应用于陶瓷文物清洗的探索研究

在文物修复的过程中,首先的工作就是对器物进行清洗,虽然现阶段清洗工艺的效果不错,但使用的试剂与手段造成污染较大,对人体与环境都会造成损害.因此,寻找新的清洗材料与清洗手段,对于文物修复工作的持续发展非常重要。为此,本研究应用干冰清洗技术,工业级清洗机器对在一件晚清胎质较厚、釉质较好的瓷器上进行了清洗实验,并对清洗工艺进行了实验与评估。实验结果表明,干冰清洗技术应用在清除瓷器表面的环氧树脂及污迹效果显著,可谓立竿见影,对瓷器的釉面未造成损害,并且整个清洗流程非常的环保、无污染,清洗完毕只剩下污迹。虽然深层次的环氧树脂清洗效果不明显,但随着今后进一步改善操作技术与清洗工艺,为最终实现环保而可持续的文物修复流程提供经验。

Rivers of dreams: on the gulf between theoretical and practical aspects of an upland river restoration

This paper is concerned with development and application of a conceptual model of the river restoration process and, through a specific case study, a demonstration of the challenges that arise when combining ecological and geomorphological principles with social and economic issues. Thus, it demonstrates the difference between the ideal goals of river restoration and the practical determinants of the nature of a river restoration that derive from individual and community goals. It begins by exploring theoretically what a river restoration project might involve. It then introduces the options developed for restoration of a particular case study river and the associated decisionmaking process. As a result of strong community involvement, institutional and financial regulations, the location of the restoration site in a National Park, and the influence of governmental and non-governmental organizations, the actual decisionmaking process resulted in a practical river restoration that departed significantly from the idealized goals of a restoration defined in purely scientific terms. It is argued that these practical limitations are likely to remain the dominant influence upon the nature and scope of river restoration projects.     

湿热加速老化法降低古籍修复用纸伸缩性的研究

纸张在浸湿和干燥过程中的伸缩性是影响古籍修复用纸使用性能的重要指标。为了改善新制修复用纸的伸缩率,实验采用湿热加速老化法处理6种修复用纸样品,测定和分析老化过程对纸样伸缩性的影响。结果表明湿热老化可以显著降低纸样的伸缩性,尤其是能明显降低修复用纸的横向伸缩率和干缩率,短时间的湿热老化就能将新制修复用纸的伸缩率降至接近老纸的水平。     

No Net Loss: Wetland Restoration and the Incomplete Capitalization of Nature

The practice of restoration ecology (the creation and restoration of ecosystems)has important implications for theorizing nature in the traditions of O'Connor's'capitalized nature,' Haraway's hybrid socionatures, and other recent work in poststructural approaches to political ecology. The prominent US environmental discourse of 'no net loss of wetlands' has spurred the rapid expansion of restoration practices, which promise to open a new frontier in the commodification and capitalization of nature. Through wetland mitigation and banking, restoration science is representing entire ecosystems as abstract, mobile, and fungible entities; however, a simple reading of a restored landscape as fully capitalized is unsatisfactory. Close attention to the wetland commodification process reveals two important points: 1) the commodification and capitalization of nature is never automatic; rather, the crucial steps of abstraction and valuation are composed of negotiations between and within differentiated segments of the state and civil society, in which there are many spaces for resistance; and 2) the materiality of restoration sites provided important challenges to the commodification process, which are not contemplated within critical approaches to nature as currently constituted. The transformation of restoration sites into sites of commodity provision is incomplete at best. A major challenge for poststructural political ecology will be to specify ecological phenomena and their important role in the social construction of material environments, without falling into an ontological commitment to the primacy of ecological data.     

Diary

Abstract

The Temple of the Tooth Relic of the Buddha is the most sacred Buddhist site in Sri Lanka. The Temple complex is on the World Heritage List. It was bombed on 25th January 1998 by Tamil terrorists who are fighting for a separate state within the country. As an actively used monument belonging to a living religious tradition, comprehensive restoration was considered necessary. Yet the restoration process became much more than a technical job, guided by professional conservation ethics. Because of its symbolic value within the Buddhist community, the conservators were faced with negotiating a host of political, social and religious issues. The author, who was the Conservator in charge of the project, describes how underlying cultural values affected the restoration process.     

Between Mumford And Marx: Anatomising Imperial San Francisco

The practice of restoration ecology (the creation and restoration of ecosystems) has important implications for theorizing nature in the traditions of O'Connor's 'capitalized nature,' Haraway's hybrid socionatures, and other recent work in poststructural approaches to political ecology. The prominent US environmental discourse of 'no net loss of wetlands' has spurred the rapid expansion of restoration practices, which promise to open a new frontier in the commodification and capitalization of nature. Through wetland mitigation and banking, restoration science is representing entire ecosystems as abstract, mobile, and fungible entities; however, a simple reading of a restored landscape as fully capitalized is unsatisfactory. Close attention to the wetland commodification process reveals two important points: 1) the commodification and capitalization of nature is never automatic; rather, the crucial steps of abstraction and valuation are composed of negotiations between and within differentiated segments of the state and civil society, in which there are many spaces for resistance; and 2) the materiality of restoration sites provided important challenges to the commodification process, which are not contemplated within critical approaches to nature as currently constituted. The transformation of restoration sites into sites of commodity provision is incomplete at best. A major challenge for poststructural political ecology will be to specify ecological phenomena and their important role in the social construction of material environments, without falling into an ontological commitment to the primacy of ecological data.

微生物诱导碳酸钙修复汉白玉石梁裂缝试验研究

石质文物劣化后产生裂缝等病害,需要恰当的修复方法。本研究应用微生物诱导碳酸钙沉积技术修复汉白玉石梁裂缝,模拟石质文物裂缝修复。研究对象为带V型槽的非贯通和贯通裂缝的汉白玉石梁(尺寸为40 mm×40 mm×160 mm),修复方法为先注浆后自由下渗。通过对比石梁修复前后破坏荷载和强度的变化以及CT扫描技术可视化非贯通裂缝修复过程来评价修复效果。结果显示:修复后石梁裂缝表面致密光滑,颜色与母材相近,整体美观性好;非贯通裂缝修复后破坏荷载均有所增加,贯通裂缝修复后的抗折强度能恢复到原有强度的35.12%,均值为3.684 MPa,最高能达到5.234 MPa;CT扫描结果定性和定量均表明胶凝体密度随修复进行而增加,接触面修复质量弱于其他位置。     

由“乾隆大阅甲”的修复谈文物的修复原则

本文针对在“乾隆大阅甲”修复过程中所涉及到的种种问题进行了详细地分析和论述,深入探讨了对文物修复原则的理解,同时,列举实例阐明国内、外的文物修复惯例和要求。在遵循文物保护的基本原则———“不改变文物原状”的前提下,制定出修复方案,得到了满意的修复效果。最后,在理论探讨与实际修复的基础上,得出这样一个结论:要综合考虑所修文物的时代、文化背景和传统习惯等,并结合现代科学技术与手段,具体问题具体分析,目的是体现文物的三个价值。对于修复标准来讲,是没有绝对和唯一的,一件文物的修复只有最适宜的方案,而无标准方案。

乾隆时期宫廷瓷器修补

陶瓷修复史是中国陶瓷史和手工艺史重要内容之一。随着制瓷的发达和藏古瓷之风的盛行,陶瓷器修复在明清时期发展出适用各阶层需求的多样工艺。至乾隆时期,酷爱陶瓷的清高宗更是直接指示了宫廷陶瓷的修补、修复和修整。本文界定了乾隆时期清宫瓷器修缮的范围概念,试图分析以《活计档》为主的清宫档案,与传世实物相印证,还原当时陶瓷器修复的工艺方法、步骤过程,以及修复地点和工匠的情况。通过修补痕迹和工艺细节,修正和补充了对部分清宫藏高古瓷器的认识。乾隆皇帝对不同的陶瓷器选择了迥异的处理方式,体现其审美好恶、品鉴素养和性情意识。
