对超声雾化过程中的液滴粒径分布和浓度特性进行了实验研究。样品为甲醇、乙醇和正丙醇的水溶液。雾化液滴的粒径分布服从正态分布，其中值粒径和标准差由超声条件和液体性质来表示。对超声雾化液滴分别采用壳核模型进行了分析，壳核模型中的溶质和溶液分别为溶质和溶液。液滴表面溶质量与分子体积的乘积随溶质摩尔分数的增加而增大，与醇类无关。根据液滴的直径分布和表面溶质量估算了伴随液的比例和伴随液中溶质的摩尔分数。
The droplet diameter distribution and concentration characteristics in ultrasonic atomization were experimentally studied. The samples were aqueous solutions of methanol, ethanol and 1-propanol. The diameter distribution of atomized droplets showed the normal distribution, and the median diameter and standard deviation were expressed by means of the ultrasonic condition and the liquid properties. The concentration characteristic in ultrasonic atomization was analyzed by using the model of shell and core to the atomized droplet, where the former and latter consist of solute and solution, respectively. The value, which was surface solute amount in droplet multiplied by the molecular volume, increased with increasing solute molar fraction in bulk liquid and was independent of alcohol kinds. The rate of accompanying liquid and the solute molar fraction in accompanied liquid were estimated from the diameter distribution and the surface solute amount in droplet.
