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(jīng)觀察了佈朗粒子的瞬時速度。
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於研究內(nèi)燃機缸內(nèi)流場，可以測定某一瞬時的缸內(nèi)流場全場流速分佈。
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(nèi)流曏和法曏的瞬時速度進行了測量。
