立体粒子成像速度用于测量在氩气直流辉光放电等离子体中1.2微米氧化铝粒子尘云的形成。这些测量显示了云形成过程中粒子速度的重新分布。此外，这些测量表明，由于中性阻力效应，粒子云在比预期慢100倍的时间尺度上达到平衡。
Stereoscopic particle image velocimety is used to make measurements of the formation of a dust cloud of 1.2 microm alumina particles in an argon dc glow discharge plasma. These measurements show a clear redistribution of particle velocities during the cloud formation process. Furthermore, these measurements suggest that the particle cloud reaches an equilibrium on a time scale over 100 times slower than expected due to neutral-drag effects.
