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

青海大通县出土汉代玻璃的研究 总被引:1,自引:0,他引:1
本文共对12件玻璃样品进行化学组成分析.其中,部分样品还进行了密度测定,X 射线衍射分析和显微镜观察.此外,还对一颗黄色玻璃珠的表面层进行 SEM-EDX 分析.结果表明,该玻璃珠表面有金箔涂层.根据分析结果,青海大通县出土玻璃的基础成分可归为三类,即铅钡玻璃(Na_2O-PbO-BaO-SiO_2系统玻璃),钠钙玻璃和钾硅玻璃(K_2O-SiO_2系统)。此外,还对玻璃的来源进行了探讨. 相似文献

城市居住区周边土地混合度对居民通勤交通碳排放的影响——以南京市江宁区典型居住区为例 总被引:1,自引:0,他引:1
建立低碳城市发展模式和都市空间结构是当前城市规划的重要实践内容之一。结合对南京市江宁区典型居住区的调研数据,文章初步分析了城市居住区周边土地混合度对通勤交通碳排放的影响。结果表明:①城市中心区土地混合度与通勤交通碳排放呈高度负相关;②在通勤交通碳排放中,私家车通勤碳排放占主导地位;③不同小区居民通勤交通碳排放呈现明显差别,城市中心区居民低碳排通勤交通方式特征显著,而城郊居民通勤方式呈现高碳排特征;④城市中心区土地混合度与低碳出行比例呈高度正相关。未来,应适当提高各城市功能区土地混合度,改善居民的通勤结构,进而减少通勤交通产生的碳排放,构建低碳城市。 相似文献

Boosting nationalism with non‐nationalist ideology: A comparative biographical analysis of the Chinese communist revolutionaries 下载免费PDF全文
Luyang Zhou 《Nations & Nationalism》2018,24(3):767-791
This article conducts a comparative biographical analysis to explain why the Chinese Communist Party's (CCP) revolutionaries used non‐nationalist Marxism to boost a nationalist movement. It argues that these people, based on their own observations of the precommunist Chinese nationalism, thought that China lacked structural conditions for making a solid nationalist movement such as cultural homogeneity, mass literacy, and a shared pride in modern history. They thus turned to seek a non‐national ideology that could still fulfil the functions of integrating leading elites, mobilizing the masses, and motivating the patriots themselves. Then, to explain why the CCP leaders particularly adopted Marxism, this article draws comparison with the Kuomintang (non‐communist nationalists) elites who advocated for more patience and insistence to develop regular nationalism. The comparison shows that the CCP's impatient jump stemmed from their disadvantaged backgrounds that had limited their ideological horizon: lower‐class origins, narrow overseas experiences, poor education, and weak attachment to traditional culture. To pre‐existing literature, this article makes three contributions: (1) provides a more detailed interpretation of the CCP's diagnosis of Chinese nationalism; (2) explains why the same structural dilemmas produced nationalist and non‐nationalist responses alike; and (3) draws a biographical database of the CCP and the Kuomintang. 相似文献
