本文提出一种利用脉冲激光产生可重复的宽带标准声源、对超声换能器的速度灵敏度进行标定的新方法—激光超声法。
A new method for calibration of velocity sensitivity of ultrasonic transducers with a wide band standard acoustic source generated by a pulsed laser is proposed.
模拟结果表明，在本研究所用的几何布置和换能器与时间相关的速度入口边界条件下，反应器中形成了一个稳定的驻波声场；
The simulated results show that a stable acoustic standing wave is formed in bubble column under the geometric arrangements and the transducer boundary condition employed in this study.
