A mathematical model is proposed to describe the sampling bias in anisokinetic sampling of aerosols. The nozzle sampling bias is described as a function of the particle's free stream inertial parameter, P, and the particle's free stream Reynolds number, Re0, and the suction ratio, w0, of the sampling nozzle. Tables of experimental values for these parameters were developed from Badzioch's experimental data, and the proposed mathematical model was developed via trial and error fitting of the results to many possible mathematical models.
提出了一个数学模型来描述气溶胶等速采样中的采样偏差。喷嘴采样偏差被描述为颗粒的自由流惯性参数P、颗粒的自由流雷诺数Re0以及采样喷嘴的抽吸比w0的函数。这些参数的实验值表是根据巴齐奥赫的实验数据编制的，所提出的数学模型是通过将结果反复试算拟合到许多可能的数学模型而建立的。
