1) wind direction frequency weighted
风向频率加权
1.
A wind direction frequency weighted(WDFW) method based upon the atmosphere wind direction frequency characteristics,combining with solving the 3D Navier-Stokes equations,the mass and heat transfer equations as well as the standard k-ε turbulence models was proposed to model the local airflow and the dispersion of vehicular exhausted plume under real atmospheric conditions.
根据大气风向频率特征,提出风向频率加权(W DFW)方法,结合求解三维N-S方程、传热传质的对流扩散方程和k-ε湍流模型来预测实际大气条件下局地大气流动和污染物扩散规律,并与现场采样分析结果进行对比。
2) weighted frequency

1.
Both of attribute weight frequency and strong compressible set are used to simplify discernibility matrix so that computing complexity is decreased and reduction efficiency is.
同时利用属性加权频率和强等价集概念化简区分矩阵,既减小了计算复杂度又提高了约简效率。
补充资料：风向袋
常设在机场的指示风向和大致表示风速的装置。为悬于一定高度杆顶的圆锥形布袋。有风时风吹进袋口，使锥底指示风的去向；布袋的倾角愈小，表示风速愈大。袋上有红白相间的条纹，便于空中飞行员和地面指挥员了解风向和风速。
