摘　　要：本文简述了相关测量技术的原理及特点，探讨了该技术用于流量测量所必须解决的同步信号的并行采集及相关测量数据的辅助分析等问题。在标准风洞内对气体流速进行了标定实验，在现有的水试验台架上对单相液体的相关流速测量进行了可行性研究。证明这种方法将能够比较好地解决难测流体的流量测量问题。This paper introduces theory and characteristic of correlation measurement technique anddiscusses techniques which were used to satisfy the Parallel sampling of synchronous signal andto design computer aid-analysing system for data of cross correlation measurement. We makeuse of the techniques and system for complete two researches, one is of measuring air speed inpipeline by means of hot-wire sensor, the other is of measuring flow speed of liquid in pipelineby means of thermorcouple. The experiment result proveds that this method will be used tothe measurement of the some fluid.
