摘要
对水的过冷度的研究在冰蓄冷和低温生物等许多领域都有重要意义。通过引起压力场的波动 ,超声波能够对水的过冷结冰过程产生影响。经对 80 0kHz超声波作用下 ,水的过冷度进行实验研究 ,发现超声波能够大幅度降低水的过冷度。超声的这种作用与空化现象有关。
The research on the supercooling of water is important in the fields of ice storage and cryobiology.The pressure fluctuation brought by the ultrasound will influence the supercooling and nucleation process of water.In this study experiments are carried out to investigate the supercooling of water under 800KHz ultrasound.It is found that the ultrasound can markedly decrease the supercooling degree of water.This effect is thought to be related with cavitation.
