工业超声波使用的频率为10KHz～10MHz,其强度为10~(-3)W/cm~2～10~5W/cm~2,大多数大功率超声设备为20～60KHz。延迟线路与控制器、医用超声设备使用的频率多为兆赫(MHz)和功率密度毫瓦(mw/cm~2)的范围。 大功率超声辐射动物实验可引起各种不良的生物学效应。如生物物理学的热效应,组织裂解机理,耦合腔穴作用,以及超声对耳、眼、睾丸、神经系统,畸胎,遗传与细胞方面的生物效应。
Industrial ultrasonic frequency of 10KHz ~ 10MHz, the intensity of 10 ~ (-3) W / cm ~ 2 ~ 10 ~ 5W / cm ~ 2, most of the high-power ultrasound equipment is 20 ~ 60KHz. Delay lines and controllers, medical ultrasound equipment, the use of more than the frequency of megahertz (MHz) and power density milliwatts (mw / cm ~ 2) range. High-power ultrasound animal experiments can cause a variety of adverse biological effects. Such as the thermal effects of biophysics, the mechanism of tissue lysis, the action of coupled cavities, and the biological effects of ultrasound on the ears, eyes, testes, nervous system, teratology, heredity and cells.
