摘　　要：本文结合单倾斜热线和五孔探针测量方法，使用周期多点采样及集平均技术，自行研制开发了一套适合于流体机械内部流场动态测量的数据自动采集和实时处理系统，并将它应用于流体机械叶轮出口三维流场的测量。文中给出了两个测量例，验证了本方法和测试系统的实用性和可靠性。In this paper, based on the measurement methods of single slanted hot wire and five-hole probe, a set of automatic data collecting and real time processing system with the periodic multi-sampling and ensemble average techniques has been developed. The system which is suitable for the dynamic measurement of internal flow field of fluid machinery has beed used to measure the outlet three dimensional flow field of the impeller. With two measurement examples presented in this paper, the applicability and feasibility of the system and its measurement method are verified.
