| 摘 要： | 本文简要综述在超声作用下，液体中空化气泡快速闭合瞬间所产生的放电、发光、高温、高压、高能量密度、冲击波、微冲流、微聚变、高精度时钟等奇特的理化效应。这些效应构成了近年来迅速发展的超声治疗、超声手术、超声美容等的物理机制，也为设计、改进及合理应用这类超声治疗仪提供了科学依据

| Abstract: | The rapid collapse of cavitation bubble in liquid under ultrasonic action can produce many peculiar physicochemical effects,such as electromagnetic radiation,light emission,high temperature,enormous pressure,shock wave,micro jet flow,micro fusion,energy amplification and extremely high stability of the luminescing bubble.These effects constitute the mechanism of ultrasonic therapy,and provide scientific basis for design,improvement and clinical application of suchlike ultrasonic therapy equipments. |
