中文摘要： 汉阳陵地下博物馆是迄今为止世界上最大的全封闭展馆，其空气质量监测空白，没有连续的观测数据研究这种新的文物保存方式对文物的定量影响。本项目拟在该博物馆建立室内空气质量观测系统，实时监测遗址区内对陶俑等文物有重要影响的微环境变化；开展微气候、腐蚀性气体、气溶胶理化成分为期三年的联合观测，并通过SF6示踪气体定量评价展室内空气密闭程度，获得关键空气污染物的变化特征及其化学反应机制；对比土遗址本体、返碱部位及陶俑表面风化物的物理化学组成和微结构特征，结合模拟实验结果，认识污染物化学反应机制与过程，并定量评估污染物对文物的损害程度，为探讨有效的控制对策和措施提供科学依据，也为国内外遗址类博物馆大气研究提供先导性研究案例。已发表项目资助论文9篇，其中SCI研究论文6篇（其中4篇为项目第一署名资助），中文核心期刊论文3篇。

英文摘要： The Museum of Yangling Emperor Mausoleum of Han Dynasty is the largest fully enclosed museum of the world. In the past, there was no real-time air quality observation system and no continuous record of the indoor air quality (IAQ) for us to do any quantitative evaluation on this new preserving method of the antique. To solve the problems above, this project aimed to three major research tasks. First, we developed the real-time monitoring system of IAQ on the fluctuation of the microclimate that has important impact on the pottery figurine. Second, we performed a three-years’combined observation of the microclimate, corrosive gas and the physicochemical characteristics of aerosol, and to measure air tightness of the exhibition hall by the tracing gas SF6, so that to gain insight into the variation and chemical reaction mechanism of air pollutants. Third, with the help of simulation experiments, we compared the microstructure features and physicochemical properties of the earthen sites (not only itself but also the alkali efflorescence position) and the weathering crust of the pottery figurine in order to understand the mechanism and process of the pollutants and make quantity evaluation on the erosion of antiques caused by them. This study will not only provide the scientific reference for studying on damage controlling measurements, but also serve as a case study on the indoor air for other relic-type museums in the world.During the implement of this project, we have published nine papers including 6 SCI papers (4 for first acknowledgement papers) and 3 CSCD papers.
