摘　　要：利用有机玻璃、排水管、水阀染料容器板等制作了流线演示仪,采用对工作液体染色的方法,避免了工作液体和有色液体的压力差.利用本仪器,对圆形障碍物、流线体和机翼模型周围的流线进行演示,流线稳定、清晰.The streamline demonstrator was made by organic glass,drain-pipe,dye,etc.The pressure difference between working liquid and colored liquid was avoided by dyeing some working liquid.Using the streamline demonstrator,the streamlines of circular obstacle,streamline body and wing model were demonstrated,and the streamlines were stabile and clear.

关 键 词：流线 染料 圆形障碍物 流线体 机翼模型
