摘要：

Orthogonal experimental method was used to study the effects of some factors on the smoke layer interface in this paper. The results show that the effect of the volumetric flow rate of exhausted smoke is the most notable; the effects of the number of exhaust inlets and the heat released rate of fire source are less notable than the effect of the volumetric, flow of exhausted gases on the smoke layer interface; the effects of the interval between exhaust inlets, the interrelation between the number of and the interval between exhaust inlets and the location of exhaust inlets are notable; but the effects of the rest factors, the size of exhaust inlets, the interrelation between the number and the location, between the number and the size, between the interval and the location, between the interval and the size, between the location and the, size and so on, are not obvious. In addition, the temperature profiles and smoke layer interface profiles are explained.
