Due to the lack of effective environmental control systems, Emperor Qin’s Mausoleum Museum is facing problems of air pollution and excessive environmental fluctuations, which threaten the protection of the unearthed historical relics. Air curtain systems have proven to be a feasible way to improve the preservation environment, and will be applied to Emperor Qin’s Mausoleum Museum. In order to identify the design requirements of the air curtain system, a theoretical model was employed to analyze the isolation efficiency under different scenarios, and the suitable operation parameter range of the air curtain system of the stone armor pit was then proposed. Based on the geometric structure of the stone armor pit, a computational fluid dynamics (CFD) model was established, and the environmental control performance of the air curtain system was investigated in the case where the jet velocity and elevation angle are 6.0 m/s and 5^。, respectively. The results show that the air curtain system can effectively isolate the relics preservation area of the stone armor pit from the exhibition hall, ensuring the local environmental control of relics preservation. These results provide a basis for the design and operation of the air curtain system of the stone armor pit. Moreover, they provide an effective solution for the local environmental control of relics in pit structure sites.

由于缺乏有效的环境控制系统，秦始皇陵博物馆正面临着空气污染和环境过度波动的问题，这威胁着对出土文物的保护。事实证明，气幕系统是改善保存环境的一种可行方法，并将应用于秦帝陵墓博物馆。为了确定气幕系统的设计要求，采用理论模型分析了不同情况下的隔离效率，提出了石质防空洞气幕系统的合适工作参数范围。根据石材装甲坑的几何结构，建立了计算流体动力学（CFD）模型，^。，分别。结果表明，气幕系统可以有效地将石装甲坑的文物保护区与展厅隔离开，从而保证了文物保护的局部环境控制。这些结果为石材装甲坑气幕系统的设计和运行提供了依据。而且，它们为坑结构现场的文物的局部环境控制提供了有效的解决方案。
