通过几个例子讨论和量化了用于粒子图像测速（PIV）的合适示踪剂粒子的尺寸规格，特别是其流量跟踪能力。对最近液体和气体 PIV 实验中使用的各种示踪材料的审查表明，通常使用适当尺寸的颗粒。重点介绍了气流，描述了产生种晶颗粒和将颗粒引入气流的方法，并讨论了它们的优点。
The size specifications for suitable tracer particles for particle image velocimetry (PIV), particularly with respect to their flow tracking capability, are discussed and quantified for several examples. A review of a wide variety of tracer materials used in recent PIV experiments in liquids and gases indicates that appropriately sized particles have normally been used. With emphasis on gas flows, methods of generating seeding particles and for introducing the particles into the flow are described and their advantages are discussed.
