摘　　要：并流下行式循环流化床是一种具有气固接触效率高及轴相返混小等优点的反应器，有广阔的应用前景．本文从下行床结构、流动特性及传质３个方面回顾总结了近２０年来有关下行床反应器的研究成果，对进一步的研究提出了一些建议．Cocurrent downflow circulating fluidized bed is a new type of reactor possessing more effective gas solids contact, lower axial backmixing etc. Research results concerned in CDCFB in the latest twenty years are summarized in three aspects of bed structure and accessories, flow characteristics, mass transfer. The future research about CDCFB is suggested. 
