摘　　要：回顾了滴流床流体分布研究的历史和技术进步，分析了测量液体分布大尺度和小尺度均匀性的方法，讨论了改善流体分布均匀性的措施，指出了滴流床操作特性的非线性与小尺度不均匀性的关系，最后对值得深入的工作提出了建议。Research on uniformity of liquid flow in trickle beds is reviewed.The methods for determining large-scale and smallscale nonuniformity of flow distribution and the measures to be taken for improving flow uniformity are addressed.The correspondence between the nonlinearity of performance characteristics and the flow distribution is ascertained. A few suggestions for futrue study of flow distribution are also presented.
