安徽淮北烈山窑遗址发掘简报

烈山窑址位于安徽省淮北市烈山区烈山镇烈山村,2018年开始发掘,面积700平方米,分为三个区域:Ⅰ区金元窑址区域、Ⅱ区唐代末期至北宋窑址区域、Ⅲ区汉代窑址区。清理各类遗迹70余处,包括6座窑炉、52个灰坑、1条道路、14条灰沟,以及大量遗物,其中以白瓷、青釉瓷、三彩器为主,产品主要包括碗、盘、盏、罐、素烧建筑构件、黄釉印花砖等。烈山窑址很可能就是文献中记载的宿州窑,其主要受定窑、磁州窑和巩县窑的技术影响,时代划分为东汉、唐代末期至元代晚期。     

壁画酥碱病害研究概述

酥碱病害是壁画最为严重的病害之一,被称为壁画的“癌症”。因其受诸多因素的影响,使得病害产生机理复杂、修复材料匮乏和修复方法难度大等问题,严重制约着酥碱病害的修复与防治。本文系统梳理酥碱病害的成因、病害机理、加固材料、地仗修补材料,以及针对不同盐霜的保护修复方法的研究成果,客观评价酥碱壁画修复过程中的经验和教训,为古代壁画酥碱病害的防治与修复提供系统的技术参考和实践借鉴。     

Seismic Load Capacity of Historical Masonry Mosques by Rigid Body Kinetics

ABSTRACT

Kinetic analysis methods based on linear and nonlinear rigid body dynamics are used to evaluate earthquake safety of masonry structures. In this study, the formulas used to calculate the in-plane and out-of-plane load capacities of masonry load-bearing walls were evaluated and a procedure based on rigid body mechanism was proposed to calculate the out-of-plane load capacities of the walls of Ottoman period masonry mosques. New aspects of the method with respect to existing formulations is the inclusion of dynamic axial load and definition of the collapse limit spectral acceleration on the overturning wall. The calculated capacities of the mosque and individual walls were compared with the results of nonlinear pushover analysis and time history analyses performed under 1.0 and 0.5 scaled forms of nine different 3-component ground motion records. It was displayed that the seismic load capacity estimated by the proposed method is very close to the values calculated by pushover and time history analyses. The method was developed on Lala Pasha Mosque, and the reliability and applicability of the proposed methodology is verified on a different historical masonry mosque in comparison to finite element analyses results.     

WB1复合气相缓蚀剂对清代带锈铁质钱币文物的保护研究

气相缓蚀剂应用于带锈铁质文物保护是一种简单有效的方法。本研究通过对WB-1气相缓蚀剂处理前后带锈钱币的形貌检测,并结合XRD、XPS、SEM等手段对该缓蚀剂在带锈钱币表面的成膜方式进行了分析研究。结果表明,WB-1气相缓蚀剂能通过化学吸附作用在带锈铁质钱币表面形成一层保护膜,阻挡有害离子向铸铁文物内部的渗透,并促进带锈铁质钱币表面锈层组分向更为稳定的组成转变。WB-1气相缓蚀剂对带锈铁质钱币具有良好的保护效果,且不改变文物外观,符合文物保护要求。     

Do we have any genuine works by Aristotle? Francesco Patrizi da Cherso’s discussion of the corpus Aristotelicum

ABSTRACT

This paper deals with the scrutiny, as found in the Discussiones Peripateticae 1, 2–4, to which Francesco Patrizi da Cherso subjected the works of the transmitted corpus Aristotelicum, and those attributed to Aristotle outside the corpus. It explains why Patrizi rejected most of the transmitted ?uvre as spurious, and shows what would have been the most radical consequence of his hyper-critical stance, had it carried the day. Particular attention is paid to contemporary (i.e. sixteenth-century) scholarship available to, and used by, Patrizi.
