前言早在1964年,Fassel便采用了超声雾化技术,这种雾化是超声能量在接近于液体表面处空化作用的结果,况且,依据超声成雾的波动机理,其雾量与超声功率有关,而雾滴的大小却与超声频率f的2/3次方成反比,即d∝(2πσ/ρf~2)~(1/3)。因此,频率愈高,雾滴愈细,功率愈大,雾量愈多。显 Foreword As early as 1964, Fassel used the ultrasonic atomization technique, which is the result of the ultrasonic energy being cavitated near the surface of the liquid. Moreover, according to the wave mechanism of the ultrasonic fogging, the amount of fog and the ultrasonic power The size of the droplet is inversely proportional to the 2/3 power of the ultrasonic frequency f, ie, dα (2πσ / ρf ~ 2) ~ (1/3). Therefore, the higher the frequency, the finer the droplet, the greater the power and the more the mist. Significantly
