摘要
提出了一种以粒子成像、粒子散射和统计光学为理论基础的污染扩散非定常瞬时浓度场的测量原理,设计了大范围瞬时浓度场测量系统,利用该系统对瞬时扩散的浓度场进行了实际测量,通过数字图像分析和处理得到污染扩散的非定常瞬时浓度场。
A principle for unsteady instantaneous concentration field of pollution dispersion is investigated based on particle imaging, light scattering and statistical optics. The structure of the measurement system is introduced in detail. With the device and digital image processing, the unsteady instantaneous concentration field of pollution dispersion have been measured.
