Through the survey, and from the size of the simulation scenarios, people share space, time, fire, smoke spread speed and moving speed of people do a reasonable proportion of the scale;

Through the investigation, and statistics from simulation scene size, were the size, timing, fire, smoke and the rate of spread, such as speed Movement made a reasonable proportion of the zoom;

Through the investigation statistics, and from the simulation scene size, the human occupied the area, the time, the fire hazard, the smoke spread speed and human's velocity of movement and so on has made the reasonable proportion reproduce by pantograph;

Through surveys and statistics, and the area from the emulation scene, people, time, fire and smoke spread and the people's movement speed, and so did a reasonable proportion of the scale;
