摘　　要：流速测试技术是研究流场中气流流动特性的重要手段,了解现代流速测量仪器的原理和应用特点,对选择合适的仪器进行实验研究至关重要。本文介绍了国内外现代流速测试技术的原理和应用特点,并对各种测试仪器进行了流动速度测量的参数比较,依据比较结果给出了选取测量方式的若干原则,为气流流动实验选择合适的测量工具提供了有力的指导。The flow velocity measurement technology is an important means during researching the flow characteristic in the flow field. To understand the principle and application characteristic of the current flow velocity measurement instrument is very important for selecting suitable instrument to be used. This paper introduces the principle and application characteristic of the internal and extemal current flow velocity t technologies and the comparision of the measured parameters for various measurement instruments with each other. According to the comparision result, some principles for selecting the measurement method are given. That provides important guide for selecting suitable instrument and has important significance.
