也谈义县奉国寺大雄殿大木尺度设计方法——与温玉清先生讨论

在近期公布的中国文化遗产研究院等单位关于辽宁义县奉国寺实测数据和研究成果的基础上,结合笔者对该寺木结构几何解析关系的认识和调研,本文尝试从斗栱设计、屋架结构设计和材分与营造尺配合等方面进行反思,逆向寻求和推算原始设计的方法。     

紫外荧光成像技术在馆藏壁画保护研究中的应用

应用光学成像技术对文物进行科学诊断与分析,是一种非接触的、非破坏性的、直观和快速的方法。本文介绍在馆藏壁画修复材料、修复痕迹及修复评估方面,通过利用紫外荧光成像技术的实验研究,实现了对馆藏壁画修复加固材料、修复痕迹的鉴别和诊断,对馆藏壁画加固、清洗效果的有效评估,此技术在对壁画进一步保护修复中发挥重要作用。     

孙殿起《贩书偶记》的史料价值

从表面上看,《贩书偶记》只是书商出身的文献家孙殿起先生在经营古书时编录的一部图书目录,但它在著录图书之时,对与各图书相关的重要信息或多或少地作了一些抄录,这些信息包括撰者的生平传记、著述情况、书籍本身的刊刻、序跋等等,尽管零零总总,却有着十分重要的史料价值。     

浙江余姚田螺山遗址室内与现场加固试验研究

田螺山遗址是我国第一处实行原址保护和展示的南方古遗址,发掘后打破了遗址原来所处的稳定环境,导致遗址出现了一些病害。为了使得该遗址较好地保存下去,本文分析了该遗址土壤的理化性质,在此基础上,选用CB材料对该遗址土样进行了室内及现场加固试验。加固前后土样耐水性、PH值及强度等表征的对比表明,加固后的土样具有较好的耐水性,抗剪强度参数粘聚力有明显的增大,从而增加了土壤颗粒之间的粘聚力。现场小面积加固试验表明,保持了遗址原貌,渗透性好,未见表面开裂现象,同时强度也有很大的提高。     

甘肃省永登县连城鲁土司属寺壁画的科学分析和时代研究

本项研究主要是运用光学显微镜、扫描电子显微镜和共聚焦显微激光拉曼光谱技术,分析了甘肃永登连城鲁土司属寺中的妙因寺、感恩寺和雷坛中的部分壁画。分析结果表明感恩寺和雷坛壁画基本保持了明代最初的绘制风格和内容。其中感恩寺主要壁画的绘画颜料和工艺特点鲜明,表明绘制该壁画的画工不同于绘制鲁土司属寺其他壁画的工匠;妙因寺万岁殿壁画存在后期改动和重绘的情况,其中万岁殿外回廊壁画主要部分的最初绘制时间要早于万岁殿大殿内壁画的最后绘制时间;而妙因寺塔尔殿壁画则绘制于19世纪后期。     

Evidence of early medieval soda ash glass in the archaeological site of San Genesio (Tuscany)

The early medieval period marks an important turning point in the history of glassmaking, since it comprises the transition period between the mineral-based silica-soda-lime glass of the Roman tradition and the plant ash-based glass. With the aim of expanding the knowledge on the glass recipes and technologies of this period, 37 glass samples were analyzed, originating from the archaeological excavations of San Genesio (Tuscany) and dated from the fourth to the eleventh century. The major and minor element concentrations were measured with SEM-EDX, while the trace elements were quantified with LA-ICP-MS. The results were compared with published compositions of glass samples of similar age in order to highlight differences and similarities. The results offer a very interesting view on the glass circulation in the religious/residential/manufacturing center of San Genesio in the early medieval period. Most of the glass has a typical late-Roman composition, but some glass fragments are identified as soda ash glass. These are among the earliest medieval ash-fluxed glasses ever found in the Italian peninsula.     

一个展览和一个时代——“明永乐宣德文物特展”设计综述

"明永乐宣德文物特展"是一个全面展现明早期艺术的综合性文物大展。展览的最终目的是要激发大众对传统艺术的兴趣,令其得到文化的熏陶与艺术的启迪,因此,展览陈列设计所要考虑的是一个多层次的体系。首先提炼装饰元素作为视觉主题,将艺术品的美感尽可能展现给观众,同时还要向观者传递时代背景、皇帝的思想境界等信息。此外,设计者还精心挑选不同的装饰材料以营造新颖的展示环境,达到衬托文物高超工艺水平的目的。     

陕西出土明代漆棺制作工艺及材质研究

为了更好地了解亚浸水漆器的制作工艺及材质,为该类文物修复保护提供科学依据,本工作采用扫描电镜能谱分析、X射线衍射分析、红外光谱分析等技术对出土于陕西长安县明代墓葬一漆棺的制作工艺及主要制作材料进行了分析研究。结果表明,漆棺是按照木胎-纤维-灰层-漆膜-颜料的工序制作的,主要使用材料有麻、粘土类物质、生漆、金及朱砂颜料。漆棺制作工艺及材质与文献记载基本一致,是中国古代漆棺传统工艺制作的典型代表。     

Do municipal unions improve cost efficiency for the social function? A quasi-experimental endogenous stochastic frontier approach

Homogeneous national policies can generate heterogeneous effects on the territory. This paper aims to verify the impact of the entry of single Italian municipalities into an inter-municipal association on the unitary costs of the social services supplied to the local communities. Panel cost stochastic frontier model in the presence of endogeneity has been introduced based on two pillars: a counterfactual setting to verify the aggregation effects concerning a set of similar municipalities and the use of a cost efficiency estimation methodology which considers the endogeneity of output with respect to cost. The results of our analysis show that the effects of adopting associated forms of service delivery can be very multifaceted and diversified according to the typology and the degree of implementation of the Municipal Union itself. The analysis sheds light on the effects of municipalities' organisational choices, addressing the consolidation of small municipalities not in binary terms but also—and above all—suggesting that it is the type of union that impacts the possibility of convergence towards greater cost efficiency.
