摘　　要：严重事故下,气溶胶是放射性物质的重要载体。在气溶胶沉积机理试验平台上开展的气溶胶重力沉降、扩散泳等试验,重点关注气溶胶浓度的测量,因此需确定浓度测点的位置。本试验设计了容器中心和壁面附近两个测点,将两个测点的试验结果分别与理论计算结果对比,发现中心测点的试验数据与理论计算值符合较好,且离散度较小,单独中心测点测量。Aerosol is the main carrier of radioactive product in severe accident conditions.In order to carry out experiment on gravitational settling and diffusiophoresis on the facility for aerosol deposition experiment and focus on aerosol concentration measurement,it is necessary to determine the aerosol concentration measurement point position.Tw o measurement points in the container center and near the w all are designed in the experiment,and the experimental results of the tw o measurement points are compared w ith the theoretical analysis data respectively.It is observed that the experimental data of the center measurement point are in good agreement w ith theoretical calculation and its dispersity is small,so single measurement point in the center is determined for the aerosol measurement.
