摘　　要：综述国内外在中庭类建筑排烟补风方面的研究现状,包括中庭进行机械排烟时理论补风量的确定、补风速度对烟气沉降的影响、补风口位置对烟气沉降的影响、自然补风口面积对烟气层高度的影响及补风对排烟效率的影响等,总结中庭类建筑火灾时补风的理论研究成果及相关规定,指出不足之处,并对下一步研究方向提出建议。The current research situation of makeup air for smoke exhaust in atrium both in China and other countries wasoverviewed, including the theoretical calculation of smoke a- mount during the mechanical smoke exhaust in atrium, the in- fluence of velocity and vent location to smoke settlement, the influence of vent area to the smoke height, and the influence of makeup air to the smoke exhaust efficiency. The results of the- oretical studies and the related regulations about makeup air for atrium were also described. Then the shortcomings in previous studies were pointed out, and some recommendations for the main research content of makeup air were proposed.
