摘　　要：红外烟幕的光学性能测试一般依据Lambert Beer定律进行 ,但在烟幕的光学厚度较大时 ,按该定律计算烟幕的透过率会存在较大的误差。本文通过求解辐射传输方程得到烟幕透过率的精确解 ,将其与Lambert Beer定律的结果相对照 ,获得了用LambertIn the optical measurement of infrared smokescreen, considerable confusion exists regarding the applicability limits of the Lambert-Beer law of optical transmission. The exact optical transmission is solved from the radiative transport equation to compare with the Lambert-Beer law and the error of Lambert-Beer law is obtained.
