instantaneous particle velocity

基本解釋

"We've now observed the instantaneous velocity of a Brownian particle, " says Raizen.
Raizen說：”我們現(xiàn)在已經觀察了布朗粒子的瞬時速度。
In this paper recently developed Particle Image Velocimetry(PIV)was used for instantaneous measurement of the full field velocity distribution in four stroke engine.
本文將粒子圖像測速技術用于研究內燃機缸內流場，可以測定某一瞬時的缸內流場全場流速分布。
Particle-image Velocimetry (PIV) system was used to measure the instantaneous streamwise velocity and longitudinal velocity in turbulent boundary layer on a flat plate.
應用粒子圖像測速（PIV）系統(tǒng)對平板湍流邊界層內流向和法向的瞬時速度進行了測量。
