摘　　要：为了获得清晰、稳定的低温冷凝图像以更深入地研究低温冷凝的传热与流动机理,提出了一种面向对象的光-摄同轴同侧可视化方法。该方法采用环形光源内置、高速摄像仪外置的同轴布置方式进行低温系统深井结构的可视化观察,借助双轴滑轨使高速摄像仪精确定位,以研究不同工况下的低温流体冷凝流型。An object oriented visualization method with light source and camera applied ipsilaterally and coaxially was proposed to achieve clear and stable images. Three built-in ring lights and an external high speed camera are applied to achieve visualization investigation of deep well frame in cryogenic system. A biaxial slide assembly with a heavy base is used to position the high speed camera and analyse the condensation flow patterns of cryogenic fluids at various conditions accordingly.
