摘　　要：为研究出口单位流量与人流时间之间的关系,以某体育馆为例,进行对某一出口常态下的人流观测实验。通过理论计算和建立Cubic回归模型对采集数据进行了统计分析。发现:单位出口流量最大值为2人/(m.s),稳定值为0.8-1.2人/(m.s),最小值为0.2人/(m.s)。出口单位流量是人流时间的三次函数。研究结果表明:出口单位流量是随着时间的变化而变化,不是一个定值,而且单位出口流量稳定值分布在初期。本文对性能化防火设计有一定的参考价值。In order to study the relationship between export unit flow and personnel flow time, personnel flow of gymnasium exit in normal was observed by the experiment. Theoretical calculation and Cubic Regression Model were applied on analyzing collecting data. The results showed that the maximum value export unit flow was 2person/（ m·~ s）, the stable value and minimum value accordingly were 0. 8 - 1.2 person/（ m · s） , 0. 2 person/ （m·~ s）. Export unit flow was a Cubic function of personnel flow time. The result showed that export unit flow changed with the time and was not a fixed value. Export unit flow＇ s stable value was in the initial phase. It has a valuable role in performance based fire design.
