摘　　要：水的过冷受到诸多因素的影响。本文对800 kHz超声波作用下的水的过冷度进行了实验研究,发现超声波能够大幅度降低水的过冷度。超声的这种作用与由空化导致的压力波动有关。The supercooling of water is influenced by many factors. The effect of 800 kHz ultrasound is investigated experimentally in this paper. It is found that the degree of supercooling of water can be decreased greatly by the ultrasound. The effect of ultrasound is related with the pressure fluctuation induced by the cavitation.

关 键 词：超声波 过冷 水
