A thermoacoustic engine converts thermal energy into acoustic power by thermoacoustic effect without any mechanical moving parts.
热声发动机利用热声效应把热能转化为声功,系统中不存在任何机械运动部件。
The second acquisition protocol USES an output acoustic power sufficient for causing destruction of the contrast agents during ultrasound image data acquisition (10).
第二采集协议采用在超声图像数据采集(10)期间足以导致造影剂破坏的输出声功率。
This paper also studied the influence of acoustic power density, temperature and other parameters on the ultrasonic cleaning through experiment.
通过比对实验分析了驻波和清洗介质的性质对清洗效果的影响。
The complex sound field distribution of the focused transducers was calculated by the coordinate transform method, and the acoustic power was measured.
