【摘要】 <正> The enhancement of cavitation yield by bi-beam irradiation of pulsed ultrasound has been studied using eletric detection method. The cavitation yield of bi-beam irradiation of pulsed ultrasound has been obtained under the peak intensity of higher than 5 W/cm2 with frequency of 1.06 MHz to be about 3 times of the sum of the yield of two separate single irradiations. This result is of significance for sonochemistry technology.
