zone phenomenon

The construction of fire zone modeling involves two crucial steps:: establishing mathematical model for every phenomenon existing in course of a fire, and calculating some fire parameters such as compartment pressure, temperature, and height of smoke layer by solving equations.

建筑火灾区域模拟的工作核心有两部分：建立火灾发展过程中各个现象的数学模型；通过求解数学方程式得到室内压力、温度和烟气层高度等火灾参数。
