通过量热法测量了几个因素（超声波的振幅、外部静压、介质的温度和粘度）单独或组合作用于在超声处理期间转移到液体介质的功率（功率输出）的量的影响。在恒定振幅（150 μ m）和压力（200 kPa）下，功率输出随温度升高而降低。温度的影响可以通过增加压力来补偿。由于提高压力而增加的功率输出的幅度取决于压力范围和处理温度。在所研究的所有温度和压力下，当振幅线性增加时，功率输出呈指数增加。该功率输出的大小不取决于治疗的温度或压力。在40摄氏度时，由于增加压力而增加的功率输出的幅度不受声波振幅的影响。功率输出随着介质粘度的增加而增加。这种效应的大小不取决于振幅，而是取决于静压。(C)1999 Elsevier Science B.V.保留所有权利。
The influence of several factors (amplitude of ultrasonic waves, external static pressure, temperature and viscosity of medium) acting, either individually or in combination, on the amount of power transferred to a liquid medium during ultrasonication (power output) was measured by calorimetry. At constant amplitude (150 mu m) and pressure (200 kPa), the power output decreased as the temperature was raised. The effect of temperature could be compensated by increasing pressure. The magnitude of the increase in power output due to raising the pressure depended on the pressure range and the treatment temperature. At all temperatures and pressures studied, the power output increased exponentially when the amplitude was increased linearly. The magnitude of this power output did not depend on the temperature or pressure of treatment. At 40 degrees C the magnitude of the increase in power output due to increasing the pressure was not influenced by the amplitude of sonic waves. The power output increased as the viscosity of the medium was increased. The magnitude of this effect did not depend on the amplitude but on the static pressure. (C) 1999 Elsevier Science B.V.
