中文摘要	Terrorist attack in buildings by chemical and biological agents could be a fateful event which can not be ignored in our lives. Traditional idea of emergency ventilation strategy to remove the smoke or other contamination, such as fire safety design, is to supply sufficient fresh air into rooms for diluting the indoor pollutant as soon as possible, without taking notice of the different roles of the different regions in the room. However, many investigations show that, the occupants only move in a limited region of the room for evacuating when they know such emergency event occurs. So that, the emergency ventilation should emphasize on the temporal development of contaminant in the coming finite period of time after contaminant generated, and just in the partly space which can influence the people. This investigation use an occupant evacuation model of fire science, standing on the occupants, gives a more rational objective function of emergency ventilation in a large, open space. The pollutant influence on the people is evaluated by Harber's Law.
