摘要
超声波具有机械传质、加热和空化作用。高强度的超声会破碎生物的细胞,降低酶活性等;合适的低强度超声波可以促进鱼卵孵化,提高鱼类的生长速度,去除有害藻类,并能增强鱼类的免疫功能,有利于鱼病防治。
Ultrasonic wave has some functions of mechanical mass transfer, heating and cavitation. The bio- logical cells are destroyed and enzyme＇s activity is reduced by high intensity uhrasonic wave. The appropriate ultrasonic wave with low intensity has some advantages of shortening the time of hatching eggs, accelerating the growth rate of fish, eliminating the deleterious algae, and enhancing the immune function of fish.
