Abstract：
Simulates the air distribution in a building structure fire-resistance lab with Fluent software. Analyses the factors influencing pollutant distribution of the lab and compares the simulation results with actual test data. Puts forward several ventilation modes and chooses the optimal one to improve the working condition of the lab based on simulation results.
