| 摘 要： | 根据污染扩散烟雾粒子的成像理论、粒子光散射原理和数字图像技术,建立了烟雾粒子非定常瞬态积分浓度与 其散射图像强度之间的数学关系,通过烟雾粒子散射图像强度的数字化分析和处理来定量测量非定常瞬态污染扩散相对 瞬态积分浓度场。并利用该方法对烟雾扩散的非定常瞬态积分浓度场进行了实际测量。

| Abstract: | Combined with Mie scattering of smoke particles, particles imaged theories and digital image processing, the experimental investigation on the instantaneous integrated concentration field is presented in this paper. The quantitative relationship between the scattering image intensity of smoke particles and the concentration is induced. By this method the untouched, unsteady, instantaneous concentration field has been measured. |
