The result showed that the contribution of vapor phase was very important to the total PAHs emitted, while particulate phase contributed most of the total carcinogenicity.
结果表明 ：在室温下燃煤排放的多环芳烃总量以在气相中存在为主 ，但总体毒性则主要存在于颗粒相中 ；
Equations of mass, momentum and second moments for particulate phase are derived from a particle PDF (probability distribution function) equation in dilute turbulent sediment-laden flows.
从颗粒运动的PDF(概率密度分布函数)输运方程出发建立颗粒相的质量、动量和脉动速度二阶矩方程。
The soot particles are oxidized by about 70 ~ 80% in the late combustion phase. And then, the mass concentration of particulate equals to the concentration in the tail pipe.
在燃烧后期，约70 ~ 80%碳微粒被再次氧化，此后微粒质量浓度接近于排放水平。
