随着工业和医学研究技术的发展,必须精密测定声能量。采用古典的超声流测量技术比较困难,因为比较复杂,又要使用昂贵的设备,而且由于非线性效应和空化使读数困难。量热法没有这些缺点,又能为不熟练的实验员所掌握。长期来,由于超声产生的热效应为测量绝对功率提供了简单直接的方法,若对超声流进行总的测量,它能具有高的精度。量热法依据总的声功率转 With the development of industrial and medical research techniques, the sound energy must be precisely measured. Classical ultrasonic flow measurement techniques are more difficult because of the complexity and expensive equipment used, which makes reading difficult due to non-linear effects and cavitation. Calorimetry without these shortcomings, but also for inexperienced laboratory staff to grasp. In the long run, the thermal effect of ultrasound provides a straightforward and straightforward way to measure absolute power, which can be highly accurate if the total ultrasonic flow is measured. Calorimetry is based on the total sound power transfer
