摘　　要：对鼓泡流化床中的气泡进行了图像处理方法研究,提出了气泡尺寸与气泡上升速度的图像测定方法。将图像测定的单个孤立气泡的上升速度与气泡的当量直径进行关联,并与Davidson＆Harrison公式进行比较,发现两者吻合较好。本文的意义在于提供了一种研究鼓泡流化床气泡特性的新的方法。The bubble parameters in the bubbling fluidized beds are studied based on image processing technolo- gy. The method of measuring the bubble velocity and equivalent diameter of single bubble is put forward. The ex- perimental data of bubble velocity and equivalent diameter of single bubble conform to the empirical formula put forward by Davidson & Harrison. The purpose of this study is to provide a novel method for investigating the bubble characteristics.
