摘　　要：采用一级多次散射近似的方法求解烟幕消光的辐射传输方程 ,获得了一种在 L ambert- Beer定律适用范围以外高精度计算烟幕透过率的数学模型 。The radiative transport equation of smoke extinction is solved by the method of first order multiple scattering approximation. The result which is more accurate than Lambert Beer law is used to simulate an infrared smoke transmission test.
