摘　　要：激光多普勒测速仪（LDV）的应用日益变得广泛，由于环境条件、物理和几何上的可达性以及流动的复杂性，使人们在每个具体应用中，需要对仪器参数合理地设置和实验装置全面地考虑．通过对一个轴流压气机转子尖区内流场的反复测试，比较精细的流动结构被揭示出来．这里所阐述的LDV测量技术，在其它方面的应用中，也具有一定的普遍意义．The applications of Laser Doppler Velocimeter (LDV) for fluid flow measurements areever increasing. Because of differences in environmental conditions, physical and geometrical accessibility and the complexity of the flow, each application requires a comprehensiveconsideration in order to ensure proper set up of the LDV parameters. Through a numberof measuxements of the internal flow field in the rotor tip region of an axial-flow compressor,more details of the flow structure were revealed. The LDV measurement techniques describedin this paper are useful for other applications of LDV also.
