particle image velocimeter (Particle image velocimeter (PIV) is a laser-based technology which, when combined with a high-speed camera, can be used to measure in real time the velocity of the water, that of the gas bubbles it may contain as well as their velocity vectors in water model of mold, which can be used to determine the water and gas flow patterns. 质点成像测速仪以激光技术为基础，与高速摄像机相结合，可用于实时测量结晶器水模中的水流速度、水中气泡速度以及它们的速度矢量，用以确定水流和气流的运动模式。); particle image velocimeter (【技】以激光技术为基础，与高速摄像机相结合，可用于实时测量结晶器水模中的水流速度、水中气泡速度以及它们的速度矢量，用以确定水流和气流的运动模式。) |
