1·Pre-evacuation time for occupants and its effect on fire risk assessment;

火灾风险评估是减少和控制火灾的基本手段。

2·The crowd evacuation time in a fire includes the preevacuation delay time and the travel time.

火灾中人员的疏散时间主要包括疏散前的延迟时间和在通道上的疏散时间。

3·The distance between the two doors and the width of the door has little effect on the evacuation time.

两门之间的距离和门的宽度对疏散时间影响不大。

4·The results show that the mixture evacuation style by using stairways and elevators will decrease the evacuation time effectively.

采用楼梯和电梯相结合的混合疏散方式可以有效地提高疏散效率。

5·Also the relationship between the evacuation time lengths and the floor Numbers, as well as the people densities, was got from the analyses of office floors.

并针对办公区楼层进行分析，得出办公区楼层的疏散时间与人员密度、建筑层数成正比关系。

6·An evacuation time model for passengers from metro platforms is proposed from field data by considering crowd density and physical characteristics of stations.

在分析实测数据的基础上，针对地铁车站内乘客疏散时间计算问题建立了考虑人群密度、空间环境变化的数学模型。

7·The results obtained evacuation time and the number of stairs, corridor width, stair width, and pedestrians in the corridor, stairs bias strength of relationship.

结果得出了疏散时间与楼梯的数量、楼道宽度、楼梯宽度以及行人在楼道、楼梯偏向强度的关系。

8·The simulation model consists of stair component and elevator component, which are respectively based on the calculation of walking speed in stair and elevator evacuation time.

仿真模型包括楼梯疏散和电梯疏散两个模块，分别以人流在楼梯中的步行速度和电梯疏散时间的计算为基础。

9·We consider both time and space as resources, adopted the ideas of pre-allocating the resources, to avoid the congestion, and achieve the optimization of the overall evacuation time.

这些静态的方法难以做到充分利用路网道路资源，容易造成交通堵塞，从而难以达到疏散时间最优的目的。

10·Earthquake has a close connection with the evacuation status and time of rescuing, the writer of this paper sets forth the necessity of constructing an evacuation time model on campus.

本文从汶川地震中中学生的伤亡情况、人员疏散状态和疏散时间密切相关的特点出发，阐述了建立中学校园疏散时间模型的必要性。
