仿生合成石质文物二氧化硅保护膜的研究

由于二氧化硅仿生材料具有优越的耐候性,与基底石材相容性好,合成条件的温和性及对环境无污染等优点,为此制备了二氧化硅防护膜。室温下利用CTAB自组装体为模板来调控Na2SiF6水解,在石材表面制备出具有优良性能的SiO2膜,并对膜进行了XRD、SEM分析表征。经过保护处理的石材表面清洁、透明,具有突出的抵抗酸碱性能。生成的保护膜具有良好的透气性,而吸水性有所下降。另外,该保护膜还显示出优良的抵抗高、低温,耐磨,及与基底结合紧密等性能。上述研究表明,仿生SiO2膜将会对石质文物起到更好的保护作用。     

故宫古建筑内温湿度问题初探

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。

馆藏壁画的历史信息与现状调查

馆藏壁画是博物馆藏品中一类特殊的文物。在馆藏大召寺壁画、陕西唐墓壁画等现状调查研究的基础上,本文分析馆藏壁画区别于原址壁画的特殊性,并提出针对馆藏壁画特点进行历史信息与现状调查的内容框架。强调壁画揭取历史、修复史、搬运史和保存环境等历史信息的调查对于认知壁画的重要性：壁画的现状调查包括本体调查和病害调查两部分,能够帮助保护工作者以科学的视角综合评价壁画保存现状。本文分别论述调查各个方面的意义、具体内容和方法。调查结果无疑对于制定保护修复方案具有重要意义,为合理实施保护修复提供科学依据,并为后续研究和档案记录提供基础信息。     

领略贵州古村落风韵

引言：最近,受清华大学陈志华、李秋香两教授的邀请,我参与《中华古村落》大系的编撰工作。每省一卷,我承担贵州卷。每卷收录20个古村落,每个村落3000字,20幅照片。另外,写一篇一万字的《分卷序》。在此基础上,我撰写了《领略贵州古村落风韵》一文,主要介绍贵州古村落的自然环境、历史流年、地域特点、民族特色、美丽外观、鲜明个性、丰富的内涵等等。     

Railway development as Symbolising ideas of social construction: (With Special Reference to Railway Development in Australia)

The townscape of “old” Lerwick reflects its traditional focus on the sea for its economic base. The major elements in this cohesive visual character are the closely clustered houses in the steep hillside district of the Lanes, the narrow, winding principal commercial street, and the lodberries projecting out into the harbour. The latter were constructed to meet the needs of the prosperous expanding trade period of the latter half of the 18th century and first half of the 19th century. Harbour improvements in the final quarter‐century of the 1800s ended their commercial usefulness. After a century of declining use and of neglect they are being restored as part of the renewal of “old town” Lerwick.     

Selective woodland exploitation for charcoal production. A detailed analysis of charcoal kiln remains (ca. 1300–1900 AD) from Zoersel (northern Belgium)

A detailed study of charcoal burning activities has been made for the Zoersel forest (Northern Belgium) based on an inventory of charcoal kiln remains, the analyses of wood charcoal and other charred botanical macroremains and radiocarbon dating of 10 of these kilns. Age determination of the youngest kilns was refined by dendrochronological analysis of trees growing on top of these kiln sites. The results show that, although many kilns were found, charcoal was produced in Zoersel only at certain moments during late and post-medieval times suggesting that charcoal burning was not a part of the regular management practice of these forests. The wood used for the production of charcoal mainly consists of taxa of alluvial (alder) forests while the kilns are situated on sites that currently are rather dry, with an oak dominated vegetation. For the older kilns, this contrast could be explained by an important change in local soil conditions. The younger kilns may be related to the conversion of alder woodland to grassland in the lower parts of the domain, with the kilns being constructed in the nearby dryer woodland areas.     

The Conservation of English Cultural Built Heritage: A Force for Social Inclusion?

Debates about the socially inclusionary potential of heritage have to date focused principally on heritage sites and museums. Relatively little attention has been paid to the wider Cultural Built Heritage (CBH) that surrounds us in our everyday lives. This paper starts with a brief theoretical exploration of the social role of heritage and the key policy background. Then, based on an understanding of policy and action in England, this paper sets out a framework for considering how this wider CBH might contribute to social inclusion. A fundamental binary divide is made between the role of CBH as historic places and opportunity spaces in which regeneration may occur. However, in neither case is action necessarily socially inclusive. The paper concludes that a greater clarity of objectives and definitions is necessary if CBH is to meet its potential to be socially inclusionary.     

Collective Amnesia and the Mediation of Painful Pasts: the representation of France in the Second World War

This paper describes research that was designed to examine the assertion that historic designation of properties, under the heritage legislation in Canada's largest province, has a negative impact on the values of those properties. The actual selling price of subject properties was used to establish their value history trends, which were then compared to ambient market trends within the same communities. Almost 3,000 properties in twentyfour communities were investigated, in what is believed to be the largest study of its kind ever undertaken in North America. It was found that heritage designation could not be shown to have a negative impact. In fact there appears to be a distinct and generally robust market in designated heritage properties. They generally perform well in the market, with 74% doing average or better than average.The rate of sale among designated properties is as good or better than the ambient market trends and the values of heritage properties tend to be resistant to downturns in the general market.
