摘　　要：文中针对声学多普勒流速仪单点测量中存在的几个问题,提出应用虚拟仪器技术实现声学多普勒流速仪的自动测量,并建立了声学多普勒流速仪自动测量和分析系统。该系统在提高了实验精度的同时,极大地缩短了工作周期,减少了工作量。将声学多普勒流速仪自动测量和分析系统应用于紊流边界层时均流速分布的测量,取得了较好的实验成果。Aiming at the problems existing in the course of the Acoustic-Doppler Velocimeter measurement the virtual instrument technology is proposed to acquire automatic measuring of ADV.In this paper,automatic measuring and analyzing system of ADV is built.The system improves experimental precision,shortens work period and decreases workload evidently.The better experimental results are acquired using the ADV automatic measuring and analyzing system to measure the time average velocity distribution in turbulence boundary layer.
