smoke shaft的意思|示意

Finally, it is shown that with proper design of the smoking shaft, dynamic smoke pressure can be enhanced and the efficiency of smoke ventilation improved.

最后提出，通过对竖井的合理设计，可以增大热烟气的动压，达到理想的排烟效果。

Therefore, it is very important to study smoke movement and its control in the stairwell and elevator shaft.

因此，研究楼梯间及电梯井中烟气运动规律及其控制具有重要的实际意义。

It is found that large eddy simulation could more accurately predict the smoke movement in pipe shaft and guide the fire fighting design of high rise building.

笔者的模拟和研究表明：大涡模拟可较准确地预测高层建筑管道井内烟气的流动状态，对高层建筑的防火设计具有指导性作用。
