| 摘 要： | 高效的防烟装置应具有绝对隔烟、人员能自由出入隔烟场所并不影响视野等功能，而防烟空气幕可以说是一种最有效的手段。本文在前人研究的基础上，通过对烟气流动的机理分析，用理论的方法建立流场，用数学手段推导出计算空气幕的方法。

| Abstract: | The effective smoke preventing installation should have the functions such as absolute smoke insulation, going into and coming off the smoke preventing place freely, no confinement of sight. The smoke preventing air curtain is the most effective. Based on the previous researches done by others, the flow field is theoretically analyzed and the calculating method for the smoke preventing air curtain of high rise buildings is inferred by means of mathematics in this paper. |
