颗粒物最大落地浓度及其出现距离的求算方法

Solution for Maximum Ground Concentration and is Distance of Particles

本文利用迭代法计算出不同风速、不同稳定度下不同粒径颗粒物最大地面浓度及其出现位置 ,并对其与高斯扩散模式计算出的最大落地浓度及其出现位置的关系分别进行了探讨。

The Guidelines for Environmental impact Assessment suggests to make prediction on the concentration of particles(d≥15μm)according to the inclined plume mode.The author calculates different wind velocities,the maximum ground concentrations of particles with varied diameters under different stability circumstances and their distances through iterative method.These results have also been compared with those calculated by Gauss Mode.
