摘　　要：粒子图像测速技术(Particle Image Velocimetry,PIV)能够无接触、实时地获得全场瞬态流场信息,经过后处理能够清晰展示流场结构,是一种常用的流场测速手段。在本科生实验教学中引入激光诊断测试技术,使枯燥的流体力学类课程变得形象可观,帮助学生更深层次理解流场结构及流动特征,提高学生学习积极性。Particle image velocimetry(PIV)is a measurement technology to obtain full-field transient flow field information in real-time without contact.After post-processing,it can clearly display the flow field structure,and it a popular flow field velocity measurement method.The introduction of laser diagnostic testing technology in the experimental teaching of undergraduates makes the boring fluid mechanics courses more vivid,helps students to understand the flow field structure and flow characteristics in a deeper level,and improves students’enthusiasm for learning.Since the curriculum reform,classroom attendance and student activity have increased significantly,and the average student achievement has also increased significantly.
